Atari Jaguar

[keen zealot]

Nothing (black screen) on AvP.
Fight for Life works.

[sudden palm]

thanks 🙂

I'm glad because I finally have one core working for my two Misters 🤣

[waxen terrace]

Wish I went for a dualram setup so I could help with testing this core waits patiently for the single ram core that's in development

[mental briar]

same for me

I’m getting real close to setting up my machine so I can build my own core until I get a working one :p

[keen zealot]

For me, the 2025-01-09 build from GreyRogue is the most compatible so far.

Fight for Life works, AvP too.
Doom is reaching full speed, Rayman too.

[ashen spoke]

Nice!

Rayman in the Jaguar doesn’t have many sound effects, I assume that’s correct?

[keen zealot]

Flashback works too.

[keen zealot]

Normal on Jaguar, limited space in ROM chips.

[mental briar]

there are quite a few games that I think are ready to put up against original hardware

[keen zealot]

Flip Out! is broken.

[mental briar]

cybermorph too

[keen zealot]

If we have a core with Rayman, Doom, Tempest 2000, AvP & Flashback, I'm satisfied.

[ashen spoke]

but what about Club Drive? 😭

[keen zealot]

NBA Jam & Pitfall work.

[keen zealot]

No dice.

[brittle zinc]

Ok I'm not sure why but Cybermorph DOES work on @tropic rock latest core but only revision b, not revision a 🤷‍♂️

[hot rune]

The new test build breaks AVP for me, the 20241231 rework works fine with AVP and fight for life

Forgot to test the 20250105 build but AVP and fight for life is broken for me on that too

[brittle zinc]

Club Drive is working too

[ashen spoke]

It’s such a COOL game

[low dome]

Pitfall (Mayan Adventure) for the Jaguar is the worst version of all the consoles in its era for some reason (FPS - lags)

[tropic rock]

This is the only one I currently have

cksum Cybermorph\ (World)\ (Rev\ 1).j64
2273735954 2097152 Cybermorph (World) (Rev 1).j64

[hot rune]

no good for me

AVP, club drive black screen. Fight for life works though

[brittle zinc]

I'm guessing that's rev a in my set. Does it work for you?

[tropic rock]

yes

[mental briar]

weird, on mine, rev B does not work...

I don't think I have REV A

MD5 (/Volumes/Mister/games/Jaguar/1 World - A-Z/Cybermorph (World) (Rev B).j64) = 81dc55f1abaa89f4b3d510cb4c2e5fe8

checksum: 3033680922 1048576

[tropic rock]

That is only 1mb

[mental briar]

it definitely worked before hrm

[tropic rock]

That is certainly possible

I dont know what versions exist or their sizes

The one I have is 2mb

[mental briar]

checking my sources

[brittle zinc]

To be honest rev a did work on every other build, never tried rev b before but it works

[tropic rock]

It is also worth reloading mister menu and then the core and the game. I (infrequently) get something to come up that failed at first. Most failures are likely just the build inconsistencies though

[mental briar]

I’m redownloading the games. I dunno what happened but something seems fucky

[tropic rock]

The build works very well for me. Air Cars, AvP, Club Drive and Cybermorph all work for me for the versions I am running

Barkley crashes after the licensing logo for me

Iron Soldier 2 also doesnt work for me

I am trying to remember what the other non working ones were. Attack of the Mutant Penguins, this is the first time I successfully tried it...

[mental briar]

yeah, that one works and is completely playable

Arena football I think is also running at the correct speed

[tropic rock]

The DRAM was known to be running slowly before this build. With it fixed all known differences are fixed. The rest of the issues should be mistakes made or wrong documentation or failed timing slacks. If the games are stable, I would expect them to run very close to expected speed

[forest tartan]

Bit further on Kuba and Greys latest builds, FFL works fine. Club drive starts, plays the music, but no graphics displayed.

[mental briar]

Ahh, found it in another folder: 2273735954 2097152 /Volumes/Mister/games/Jaguar/4 Betas, Prototypes, Revisions, Demos/Revisions/Cybermorph (World) (Rev A).j64

Grey, what is your AVP cksum?

3240832904 4194304 /Volumes/Mister/games/Jaguar/1 World - A-Z/Alien vs Predator (World).j64

[tropic rock]

cksum Alien\ vs\ Predator\ (World).j64
3240832904 4194304 Alien vs Predator (World).j64

[mental briar]

There is a weird bug with some games that I think is related to the DV change. I can take a video of it, but the screen starts flashing...green (it's faint) and you lose all video

(aside from the flashing)

I couldn't reproduce on any non Direct Video setups

[forest tartan]

JUst to add, both are standard DE10, 256meg, HD out.

[grim ferry]

So no-intro AVP w CRC DC187F82 is incorrect?

[tropic rock]

crc32 Alien\ vs\ Predator\ (World).j64
dc187f82

[grim ferry]

Ok cool. Just making sure mine is right

[tropic rock]

crc32 and cksum are different

[grim ferry]

ah

[tropic rock]

cksum is runnable on the mister

[forest tartan]

PCN Showing off the single version of ram live now. I've asked for FFL and Club Drive, not shown it yet - https://www.youtube.com/watch?v=oFhVUsSm0Uc

[mental briar]

Air cars is so weird. It boots and does the demo loop fine. But starting a game crashes only on my misteraddons mister

[mental briar]

Did he have any time table for release?

[forest tartan]

FFL doesn't go ingame on the single core version

Club Drive works!

[brittle zinc]

I'd expect it to have the same issues GR's core does, could just be his stack or the compile

[regal rain]

I'm not finding a single RAM version anywhere to download here in the Discord...is it available, or does Pixel Cherry Ninja have a core build that's not available to the public?

[echo valve]

I believe he has a private core provided by mazamars

[regal rain]

cool, just wanted to make sure I wasn't missing anything...cool to hear a core for single RAM might be coming in the future!

[mental briar]

With every core release, the Jaguar tower of power grows…

Need to get red screws….

[marble holly]

what about red screw covers

[mental briar]

could work too

[carmine wedge]

It's missing the toilet addon

[ashen spoke]

Damn that looks so cool

[mental briar]

if grey adds CD support, I was thinking of doing a zaparoo reader shaped like the toilet bowl

[gaunt wind]

Defender 2000 has the best version of classic defender included. Is support for the six button controller on the horizon? Much needed for playing Defender as intended.

[mental briar]

the 6 button controller should work fine now

the 5 extra buttons are just mapped to existing buttons.

shoulders are 4 and 6

X Y Z is 7 8 9

[gaunt wind]

Yep. That works. Cheers.

[urban mango]

@tropic rock It was a nice surprise that backup ram is saving - I can use my keys on T2k 🙂

[spare idol]

The progress on this core is amazing to read. Worse case scenario, I'll switch out the Analog IO on my second Mister if the Single RAM implentation doesn't quite get there. Does anybody know if the Mister-Multi system can have it's Single module replaced with Dual?

[remote pecan]

AvP, Trevor McFur, Club Drive, and Power Drive Rally are broken for me with the new core. AvP, TMcF, and Club Drive are displaying a black screen with the background music, and PDR cannot go past the copyright screen.

[mental briar]

The good news is that now that grey can rule out ram timings, he can dig into the other reasons why some of these games may not load

it’s a major hurdle to get over

[dense ravine]

Or just nail varnish if you’re being lazy

[warm oasis]

Have used old Games Workshop/Warhammer black paint on screws before. I personally would go with black over red.

[mental briar]

Did black on the bottom

Gonna print out some screw hole covers in red and see how I feel

[frigid dock]

grab some black bumpons from amazon and use those

[mental briar]

how much money can I spent on bespoke shit to model my mister off a goddamned jaguar

challenge level: irresponsible

[fresh urchin]

At that point you can probably just buy a new jaguar shell?

[frigid dock]

The 3d files might even be available

https://bitbuilt.net/forums/index.php?threads/atari-jaguar-console.6252/

[covert pivot]

I'm sorry if this has been mentioned here somewhere but, is the single ram core available and where can i download it from? I know its still WIP...

[sudden palm]

There is no version for a single sdram yet.

[covert pivot]

https://www.youtube.com/watch?v=oFhVUsSm0Uc

[sudden palm]

Of course I have seen it, can you download it somewhere and play? nope. It was only a test. The core was made available by the author only for testing. That someone is trying to do it is known.

[covert pivot]

OK thank you for clearing it up...

[ashen spoke]

We’re all very optimistic and I do think it’ll happen but it’s still not a given it’ll work on single sdram.

So it’s just wait and see until then. But the dual ram version is getting better by the day which is also exciting.

[dry cedar]

Yeah please no compromise on the core

[mental briar]

The games that are running right now are running real well

[ashen spoke]

I have no concept of how fast or slow Jaguar games should be running so it would be awesome if anyone who has an actual Jaguar can verify that

To me they run great!

[mental briar]

yeah, I should really get a ram cart and take my jaguar out of the box

[ashen spoke]

that would be awesome!

Oh hey the Jaguar CD is just a disc drive right? No specialized on-board hardware?

[mental briar]

oh is it?

[ashen spoke]

I have no idea

I should probably look shit up before asking questions lol

From wikipedia:

The drive fits into the ROM cartridge slot atop the console, with its own pass-through cartridge slot to optionally run software that uses cartridge only or that uses cartridge and CD in tandem. The Memory Track cartridge stores saved game position and high scores. The Jaguar CD has a double-speed (2×) drive and built-in VLM (Virtual Light Machine) software by Jeff Minter, using a spectrum analyzer for a sophisticated video light show for audio CDs. Jaguar CDs can store up to 790MB, more than conventional CD-ROMs. Its proprietary CD format is based on the audio CD format, instead of standard CD-ROM data formats.

Seems like it uses a standard rom connection, is double speed, and has a bios with a fancy spectrum analyzer.

I wonder how it handles full motion video.

[fallow salmon]

i'm guessing megaCD level

[ashen spoke]

I found that from the Atari forums. Who knows if it's real and who knows if I can distribute it?

[mental briar]

looks like the gamedrive supports CD games

hmm

I'm cleaning out the storage room this weekend. Let me make sure I still have the jag - I am pretty sure I do.

Do I have a tv I can hook it up to? WHO KNOWS

[grizzled mantle]

Some schmatics and info on Jag CD: https://wiki.console5.com/wiki/Atari_Jaguar_CD

[ashen spoke]

you are badass, thank you!

[uncut atlas]

jag cd is all fine and dandy but really it's pretty distant right now. The core alone can't even compile stably

[fallow salmon]

i thought we had the jagCD stuff working like, years ago first time someone tried to make this core

[fresh urchin]

I mean, you can just have an option to load cds and have the core not work if that happens. It would mirror the real jag cd.

[mental briar]

yeah, I'm just thinking of future proofing (if I'm spending 200 dollars to play jaguar games, I want to make sure I can test the complete library)

[fresh urchin]

Failure rate on those things is astronomical.

[uncut atlas]

emulators exist you know

you dont NEED hardware

[mental briar]

yeah but if word got out that we used emulators....

dogs and cats, all that

[fresh urchin]

Yeah, Robby uses a pi, and look at the respect he gets.

[uncut atlas]

there's some logical breakdown in "I know this library is absolutely mediocre but I need to buy the most ideal rare and fragile hardware to play it instead of just trying the terrible games in a software emu"

I like the unity of having all the emulators on mister too, but it's not the end of the world for a system like jagcd

[mental briar]

I didn't put a lot of points into "sound financial decisions" when I made my character sheet

[still aurora]

bigpemu plays them all

jag cd , cart

no need for real hw anymore

[ashen spoke]

BigPEmu is awesome

[ashen spoke]

Yeah you’re right.

Apologies for the distraction

[still aurora]

Shame he cant open it but its based off the commercial work he did for the atari thing on steam

[outer veldt]

It handles FMV rather well, much better than the Mega CD. There is a game for the Jag CD called 'Vid Grid' which is a sliding puzzle game where you rearrange titles into a music video. It may have been a pack-in title.

[timid snow]

Def better FMV than Sega CD, but not as good as 3DO.

https://m.youtube.com/watch?v=Kmy3ERs-U4o&pp=ygUZRHJhZ29u4oCZcyBsYWlyIGphZ3VhciBjZA%3D%3D

[ashen spoke]

Oh duh, I completely forgot that game. Yeah I think it was really impressive on a technical level.

[frigid dock]

Jaguars, are they fast?

[frigid dock]

If he ever makes the source code open it would be sweet to port the emulator to other systems. And bonus if it's portable you can rename it to BigPPEmu

[mental briar]

Arena football is definitely faster in BigPemu

It also crashes on BigPemu :p

[hot rune]

He releasing BigPemu on Steam soon so I doubt the source code will ever be open
It's probably tied to the Atari 50 Devs too

[frigid dock]

Oh I'm aware I just needed a very thin pretense to lead into my PP joke

[hot rune]

It's a decent emulator of a terrible system ....

[brittle zinc]

It's open source, the core is looking real viable now, it'll happen when someone has the inclination

[uncut atlas]

not really

it's not a matter of effort but rather capacity

the reason we have all these issues with avp and things working for some people isn't a logic error, like a typo or a bug, it's the fact that the hardware itself is being asked to do more than it is capable of

so we have to try to find ways to shave stress off it and make it more efficient so the hardware can handle it stably

adding an entire additional system on top of a design that already struggles to run doesn't seem super realistic at the moment

we've learned to never say never, but realistically it would take some pretty exceptional feats to make it work

[urban mango]

The Jag I have is PAL - not sure what the state of that is in the core to make a fair comparison.
But happy to do so!

[urban mango]

Yes, it’s a nice option to have - my JagCD won’t spin discs reliably any more. The VLM was what I used it the most for! BigP is great for that as you can feed it audio from the computer.

[warm oasis]

Could Jag CD play any other formats? My assumption is it is pretty basic on that front, I assume it can play audio CDs, but probably not CD+G, VCD, Photo CD etc.

[urban mango]

It supported Audio and CD+G

[warm oasis]

Ah, so it can play CD+G as well, funny what can and can't play that format.

[uncut atlas]

the real question is: why do we care

cd+g is so meaningless

in fact, playing cd's with a 20 year old console is also pretty meaningless

IN FACT cd's themselves are totally worthless now

rotting plastic discs

[glad flame]

Always hated how finite discs are. I'm glad these SD mods for older consoles exist so you don't need to deal with the discs inevitably wearing out.

[uncut atlas]

lasers and drives being mechanical themselves of course are on a clock

but the discs too fail relatively quickly

[warm oasis]

I was confirming that it was fairly basic in what it did, the fact it only plays CDs and not other exotic formats removes extra complexities if it is ever supported.

[uncut atlas]

and I was just pointing out how unnessesary it is to even waste a thought on that

[thorny swift]

Wait till the AI robots call us all rotting meat bags

It was only a matter of time until someone thought “AI is cool. I want to bang it” 🤣

[mental briar]

finally

sexy robots

[thorny swift]

Already happened

The Crushenator exists

[warm oasis]

This feels like off topic content...

[thorny swift]

Umm…the AI bot can play Jaguar with you? Player 2!

Half the time I don’t read what channel I’m in

[warm oasis]

Something I was thinking about, if we think that maybe down the line, be even years in the future, Jag CD support is a possibility, then we would need a second BIOS for it. What would be the ideal naming convention for having two BIOS files in the core? Would it be boot0.rom and boot1.rom, or boot1.rom and boot2.rom?

If so, would it make sense to rename the BIOS file to that now while it is in development so there isn't a need to have people do this swap after it is live? Or avoid a clunkier naming convention like boot.rom and boot1.rom.

[still aurora]

its always boot.rom boot1.rom for 2

just like in every other core

[warm oasis]

I thought it was numbered when there were multiple, if that is the case then ignore my comment

[still aurora]

psx is boot.rom , boot1.rom, boot2.rom

[warm oasis]

Yep, you are right, I was sure it was boot0.rom

boot.rom => US BIOS
boot1.rom => JP BIOS
boot2.rom => EU BIOS

Cool, that's not a thing then 🙂

[warm oasis]

Has anyone tried booting the Jag CD BIOS? It is probably looking for something missing, but maybe it does show something.

[frigid dock]

It doesn't look realistic in the photo so I already have doubts

[thorny swift]

If we could turn back time (Cher) I’d have wait “boot.rom and cd.rom” for systems that have a cart and CD based rom. Spell it out literally for users

But that ship has sailed

So when users are wondering “which is which” they don’t need to remember 1 = CD…they see “cd = cd”

[warm oasis]

That does seem more user friendly

[still aurora]

they should just be called the mame names

then no changing names to boot.rom etc

[still aurora]

wrong channel ?

[warm oasis]

Oops, yep, nobody wants Photo CD chat in here 🙂

[fresh urchin]

Cd+g is definitely important- how else am I going to enjoy those two information society tracks?

[warm oasis]

Apparently the Mega CD core can play them, but the big issue with CD+G is getting working dumps, as (my understand is) the redump format doesn't support the needed sub channel data

I have the Jimi Hendrix best of CD+G disc and it is fun to play with the crude, trippy animations

[mental briar]

I got my reflex adapt and jag controller today. How can something be so cool and so dumb at the same time?

[vernal arrow]

Just got mine too…love it!!!

[still aurora]

its good to have if a thief breaks in

you can kill them with one swipe

its still one of the worst controllers in History though !

[mental briar]

I don't think we could with these cheap ones

they don't have the same heft

[still aurora]

I got a boxed Atari one a few years ago

I did use it with the adapt on bigp Emu

[mental briar]

Those 1st or 2nd run controllers are definitely higher quality. but these work in a pinch

[minor solstice]

Oh they make 3rd party Jag controllers?

[mental briar]

well, there is a pro controller, but no these are official jag controllers. but as the years progressed, the components they used to build the controllers got cheaper (and worse)

[spare idol]

When I lived in the UK circa 99 Electronics Boutique had a surplus stock clearout on Atari Jag's, games and peripherals. The clerk said that they were on a crunch to clear the stock that was sitting in a warehouse. I changed my mind buying one brand new for 40 quid as I didn't wanna haul it around the City of London all day. Where's Doc Brown when you need him? lol

[ashen spoke]

Not saying you should do this but I wonder how the repro overlays feel/look versus authentic ones.

[mental briar]

https://tenor.com/xHki.gif

[cursive cape]

I was reminded of this. https://www.youtube.com/watch?v=uhGn9KpBaBM Jaggers!

[thin sky]

Hey All. Trying to get the Jaguar core running on my setup and could use some help. Currently using direct video with an HDMI adapter to VGA to component breakout cable for my crt. This setup works fine with nearly every other core except this one and the cdi core, I get a rolling image or just a bunch of garbage. Do I need to add a video mode to the mister.ini for the core to work on crt?

[ashen spoke]

Just a heads up, both of those core are heavy in development and still has ways to go. Use straight HDMI to ensure maximum compatibility.

And even then it working is still not guaranteed.

[warm oasis]

I don't think he latest core from GR has DV video in it, does it?

Someone added the line in to enable it, and it will be added to next core (unless this happened already and this is another issue)

[ashen spoke]

Right, it doesn’t. Good memory.

[warm oasis]

There is a build somewhere in this chat that the latest build with DV video though

[mental briar]

It does

Latest core from grey has the dv update

[ashen spoke]

Oh weird, then I wonder why @thin sky couldn’t get it to work. Amigo, you’re using this core build right?

#test-builds message

[mental briar]

It’s likely something with the hdmi > vga > crt thing. We need a tubeman to help

[thin sky]

Let me know if you guys need any video, I have multiple crts.

[mental briar]

All other cores work fine? I think @brittle zinc is using a crt with the core. Maybe they can help. I imagine it’s a setting somewhere but I am a simple digital boy

[frigid dock]

What a time to be alive. Jaguar, CD-i and Saturn, all 100% complete.

[ashen spoke]

All the best game consoles!

[tropic rock]

If the option for VSync is listed then it has support for dv1 (it needs to be set to the default of vvs)

(I have not looked into how dv1 works myself)

[mental briar]

My need for a working version of AVP has crossed the rubicon of sanity

[ashen spoke]

I wonder if you had a repro of the AvP overlay how it would be

[mental briar]

Robby, I have to save things for my wife to get me for valentines day or she gets very angry

and "robby made me do it" didn't work when the jag controller showed up

[ashen spoke]

That’s what I tell my wife too, “Robby made me do it”

She looks puzzled at me and that’s when I know I’ve already won

[mental briar]

jesus by the time this installs grey will be done with the core

[mental briar]

Shhh. She’s sleeping

[brittle zinc]

Got to be a setting. I'd assume @thin sky is using RGB? If other systems work fine I can only imagine he's not using the latest version of the core. It does occur to me though I've not tried straight RGB since I'm using Composite. The sync shouldn't be any different for RGB though. Of course nothing with work without the bios in place

[remote pecan]

AvP, Trevor McFur, Club Drive, and PDR are broken for me with this core. AvP, Club Drive, and TMcF show a black screen with background music after the Jaguar sequence, and PDR freezes immediately after the copyright screen. Also, I noticed that upon the jaguar roar, the screen goes black for a couple of seconds. This wasn't happening before. Weirdly enough, Fight for Life is working for me. I'm able to load a fight and play the game.

Also, both Cybemorph roms are playable with this core, as opposed to earlier ones which only allowed for booting the one labelled Rev. B.

Arena Football loads, and the game can even be started, but after a few seconds it completely crashes.

[thin sky]

Yup, all others work fine. I bet it is the bios, don't remember me putting one on specific to the Jaguar. I'll check and follow up in a bit.

[mental briar]

I’m cooking a bunch of builds. Will post a zip in a bit

[thorny swift]

Nice

Uploaded a jag vid this morning. Very Jaguar Sunday to you all

[ashen spoke]

It’s Jagday

[thin sky]

Success boys! Confirmed working on crt with direct video conversion to component, latest core, dual ram version.

[ashen spoke]

Awesome!

[thin sky]

I forgot to rename the bios file, rookie mistake

[graceful oracle]

How many Jaguar games use a 6-button controller?

[graceful oracle]

Single core?

[thin sky]

Dual ram on a Mister Pi.

Can't wait for the core to get snac support busted out my Jaguar controller just to see lol.

[graceful oracle]

@thin sky Once the single RAM core is working well, I'm gonna get the Reflex adapter

[forest tartan]

Whare are you altering mate? THis whole Jaguar builds seems so hit and miss, great though!!!

[ashen spoke]

All the Jaguar games that use the keypad. ZYX is mapped to 789 and LR is mapped to 46.

[mental briar]

I’m just running errands. I think I have cooked 15. I’ll share em here when I get home 🙂

[graceful oracle]

@ashen spoke good to know. I was considering a Jaguar pad with 6 action buttons but not sure if it is worth it

[rotund portal]

I would for sure recommend more people give Quartus a try...

If only to see what a PITA it can be sometimes. lol

But also, just to see the process of compiling a core, and hopefully encourage new peeps to try tweaking some code.

@brittle zinc Allo.

[brittle zinc]

Bonjour 😗

[brittle zinc]

It's a lot more straightforward than I think people realise. Those who use wildcards though have a booth reserved for them in hell

[thin sky]

@mental briar will we get snac support in a beta build?

[mental briar]

I think grey said that would be hard but I can’t remember

[rotund portal]

You know I couldn't agree MORE, about the wildcards thing. lol

It's pure evil.

Also - single-letter signal/bus names.

[mental briar]

(I’m not a dev, I installed quartus irresponsibly and am now mad with power)

[rotund portal]

But yes, doing some basic tweaks probably isn't half as scary as people tend to think.

I think the majority of the cores are in Verilog, which is quite close to the syntax of C.

[thin sky]

I have both snac and reflex. Reflex works great with everything, including retroarch on a PC.

[brittle zinc]

Yeah I have to admit, I tend to run away screaming when I see vhdl

[rotund portal]

Anyone can be a "dev". I just don't consider myself an "uber dev". 😛

The uber devs include the wizards like Jotego, Sorg, Srg320, Robert, etc.

[rotund portal]

Honestly, I have tried with VHDL, many times.

But I was trying to do quite a "simple" tweak of ASCAL the other day, and I still haven't managed it.

I mean like something I reckon would have taken me ten minutes in Verilog. I tried for over an hour to wrap my brain around the VHDL, and still didn't manage it.

13 builds. LOL

Dayum.

Having said that, I've done probably 12 Quartus compiles, just today.

[sudden palm]

at the moment only two games do not work for me, Iron Soldier 2 and Barkley Shut up and Jam! core is completed 😛

[rotund portal]

I tried tweaking the Jag core earlier, to see how far I could get with some Jag CD stuff...

The build was SO unstable, it would often only show the BIOS logo once, and then never again.

Sometimes even after reloading the core, it wouldn't show the logo. It's incredibly frustrating.

I have no idea how people ever learn how to do proper timing closure either.

I read quite a few white papers and PDFs on using TimeQuest, still don't get it.

[mental briar]

@forest tartan #1055574003810578503 message

[rotund portal]

You can tell TimeQuest to "Report Top Failing Paths", or "Timing Closure Recommendations" but it's very hard to learn how to actually fix what it suggests.

Also, the Jag core is just haunted.

The worst part about trying some Jag CD stuff, is I just needed the core to work a FEW times. lol

And I could have done a SnargleFlap capture, to see if the Jag CD BIOS was doing anything at all.

But nope... haunted core.

Oh yeah, and I even tried the Design Space Explorer on the Jag core last night...

Even that broke. lol

I hadn't used it in years.

It's basically a tool that gets installed alongside Quartus.

That lets you run multiple compiles, but with different seed values, etc.

To try to find the "best" overall core.

You can tell it to optimize for Area, Speed, or Power usage, like in Quartus.

The Jag core didn't even let one compile finish, without breaking DSE.

Even when a core did show the logo, it randomly started corrupting the graphics.

https://cdn.discordapp.com/attachments/1315008851874938948/1327850040663867482/IMG_1705.jpg?ex=678538f7&is=6783e777&hm=e10076ff84316301c45b1492f012142f24445a8260258cfbda1b8dc14b1359ea&

I don't think I'd even tweaked anything in the code at that point. lol

I just finished watching VGE's vid on the Jag core.

"Fight For Life" seems like an Alpha tech demo.

I can't believe they used to charge people actual money for that cart. lol

[mental briar]

dude

that's every game (aside from a couple of ports and tempest)

it's WILD that people were expected to pay money for some of these games

I love it

[sudden palm]

https://tenor.com/view/im-watching-watch-you-eyes-on-you-kid-cute-gif-16282723

You are going in the wrong direction, turn around. This is Jaguar's sacred ground 😅

[mental briar]

Hey, you can love things that are bad. I love The Core. Have you ever seen The Core? Terrible movie. I love it

[rotund portal]

Don't get me wrong, I love the jank, too.

I also love the movie The Core.

2003, I think?

Swank.

[mental briar]

such a bad good flick

[rotund portal]

And the guy from Deep Blue Sea. Aaron Arronheart, or whatever he's called.

I think it was great. lol

[mental briar]

and tucci!

[rotund portal]

It even has the "mole" kid, from Road Trip.

[mental briar]

and lindo!

[rotund portal]

Yeah.

[mental briar]

and the guy that always plays a french dude in american films

[rotund portal]

It's one of those films I wish I'd seen at the cinema.

But I'd barely heard of it, until years later.

The guy who was in the Space Station in Armageddon? lol

[mental briar]

no no, and not the professional

the third tier french guy

https://en.wikipedia.org/wiki/Tchéky_Karyo

[rotund portal]

Always forgot his name, and get him mixed up with Jean Reno.

Oh yeah, him

[dusty pollen]

I haven't been keeping up on the jap core, the Single SD ram core shown on PCN chan is private still right?

[mental briar]

yeah. a lot of work to still do there

[dusty pollen]

coo ty much

[mental briar]

I wouldn't hold your breath, but anything is possible :). It's in good hands

Maz is one of the devs that could pull it off for sure

[rotund portal]

Now I want to see a meme, with the movie "The Core", but with the Jag logo.

[dusty pollen]

with ram prices dropping with the clones not to bothered by doubling up

[ashen spoke]

I would say it’s not worth it considering the prices. Now this is just my opinion but I think having to use the keypad is a better experience because of the overlays.

[rotund portal]

Yes, I think now that Maz is also looking at it, the combined forces of GR, Kitrinx, and Maz might finally get this core up-to-snuff.

(I take credit for none of it. I haven't really tweaked the core much, since the initial port. lol)

btw, if any devs on here do know about how to do Timing Closure, please let me know.

I probably shouldn't say this (again), but - Jag CD...

There isn't a whole lot in the CD drive itself.

And not too many commands.

If those were forwarded to the main MiSTer process via the hps_ext thingy, I don't think it would be too bad to implement.

[thorny swift]

New task haha

[rotund portal]

But... that's all assuming the core timings can be made more stable first.

Which is quite a giant problem atm, because I'd NEED to use SignalTap to debug it.

(and enabling SignalTap can also affect timings, when the core is already marginal.)

https://github.com/mamedev/mame/blob/fb60da7510c3d7295762d68b7372b7ea920c388c/src/mame/atari/jaguar.cpp#L1132

[lyric pelican]

CD-Rom emulation, chip codename Butch (the HW engineer was definitely obsessed with T&J somehow ...)

[rotund portal]

Only one small address range for the commands / status, too.

[brittle zinc]

It seems to me newer de10s seem to fare better with this core. Oddly 128mb + 32mb also. But yeah the slack is horrendous

[rotund portal]

And an IRQ hookup.

[rotund portal]

Wish I knew how to actually do this...

https://cdn.discordapp.com/attachments/1315008851874938948/1327850581728952401/image.png?ex=67853978&is=6783e7f8&hm=8c0d70fc44e7a0a14aebc7417a19a71ee4bb71b7f18575abfe4f6c8dad713d6c&

[brittle zinc]

IMHO worth it just for Jeff Minters VLM

[rotund portal]

I sort of get what TimeQuest is saying, overall.

But no idea what to actually move around.

I tried for about three hours last night. All I wanted to see, is if the CD BIOS would access the Butch registers.

And I don't mean the till, at a lesbian bar.

[brittle zinc]

I tried timequest's suggested seed generations and every one was worse 🤷‍♂️ maybe feed the suggestions into gpt and see how much that's suggested changes fucks it up 😂

[rotund portal]

I never thought of asking ChatGippity.

I've been using Claude AI a fair bit recently, to help with some Verilog.

It's been pretty good, but obviously have to be careful for it's dumb mistakes.

I don't get why, with most AI language models atm, they seem to know exactly what's wrong with the code if you mention it.

But they don't seem to do that kind of error-checking "offline".

ie. if it knows what the problem is, why not fix it to begin with? lol

Maybe I'm not understanding how the whole process works.

Jag CD does only use EINT0

(External Interrupt 0)

[ashen spoke]

Ok no @rotund portal has escaped containment! Were the #1315008851874938948 guards asleep!?

[rotund portal]

The implementation in MAME for Jag CD definitely isn't finished, btw.

But it implements just enough (register readback), to allow the BIOS to start on MAME.

lol

I think I need a break from Dreamcast... for a few months.

It's killing my brain.

Right now, the renders on MiSTer are looking terrible again, and I could swear I did another git commit last night.

[ashen spoke]

I think it’s cool as hell regardless, I love following your updates.

[warm oasis]

If we can keep your tinkering in the Dreamcast channel Ash, it is just going to confuse people in here. Let's keep this channel for Greyrogue's and Kitrinx's work on getting the instabilities fixed in the core.

Appreciate you looking into what it would take to get the Jag CD BIOS to boot, but realistically the core is a long way off being stable enough for anyone to look at adding in Jag CD support

[brittle zinc]

That's a bit derogatory. There wouldn't be a Jag core without Ash and it's interesting and related. To call it "tinkering" is a bit insulting

[warm oasis]

It wasn't meant to come across that way, hopefully you didn't take it that was Ash, you know I appreciate the work you do - especially on digging into the Jag CD BIOS stuff

[rotund portal]

90% of what I said was Jag-related. I can't imagine a better place to post it.

[remote pecan]

Tried AvP on all 13 cores from the archive. Here are the results:

1, 2, 6, 10, 12, 13 - black screen with background music;

7, 8, 9 - working without any noticeable issues;

3, 4, 5, 11 - black screen without any activity.

[brittle zinc]

Yeah that seems to be the 3 states everyone else has reported

[remote pecan]

Fight for Life, Flashback, and Arena Football '95 seem stable to me with ## 8 and 9 as well. With # 7, Arena Football hang in a few seconds after a match was started.

[mental briar]

check Club Drive and trevor mc fur

[thorny swift]

Never before have this many people played Fight for Life at once. Even back when it was new haha

[remote pecan]

Both are working without any noticeable issues on ## 7, 8, 9. I'll recheck them on the rest of the cores just in case.

[thin sky]

So I just tried avp on real jag hardware, retroarch virtual Jaguar and Mister. Ironically overclocking the Mister core with turbo is most smooth fps.

[warm oasis]

I know last night @rotund portal you mentioned you were surprised to see so much old code in the Jag core still, are there areas you know of that could benefit from being refactored and maybe help get the core stability improved?

[remote pecan]

I've checked the rest of the cores. Only ## 7, 8, 9 are functional. Some are able to play music, but most of them are only displaying a black screen.

[mental briar]

sounds like 8 or 9 are your winners

so far for me, 4 on my mister pi loads everything. 2 on my retrocastle loads everything. I need to figure out the misteraddons stack next

[remote pecan]

Yep, 100% correct. I'll try a few other games to check if anything is still broken.

[remote pecan]

What batch are your Mister Pi from? Mine is from the 2nd one.

[mental briar]

I'll try to do this every time grey does a build (until the build is more stable). Save Kuba some cpu cycles :). It's ~12 minutes a build, though, so it will take time to get this many for the next build

[mental briar]

the dual ram build I have is a batch 2 mister pi (I have a batch 1 single ram as well). but keep in mind that the core is very finicky right now, so it's really about finding a seed that works with your specific hardware configurations. even though mine is a batch 2 doesn't mean it will work with the same build as yours (thats why I built so many)

[remote pecan]

Ok, I see. So there's even more randomness in the core than I thought.

[mental briar]

Which cybermorph is working for you?

[mental briar]

ok yeah, that's the same one working for me. It's weird that the other one just doesn't work anymore

[remote pecan]

For the record, Iron Soldier is working for me, as both Cybermorph roms are.

[sudden palm]

Iron Soldier 2 ?

[remote pecan]

Ah, didn't notice that you mentioned the sequel.

[sudden palm]

No prob👍

[mental briar]

yeah, shut up and jam and iron soldier 2 are the current white whales

not sure we have seen a build that loads either

[sudden palm]

what version dosen;t work ?

[mental briar]

Mine is labeled “REV B” and is only 1mb. It worked with older versions of the core, but not the latest

my REV A works fine

[sudden palm]

for me works fine A and B

2 and 1mb

[mental briar]

well poop

[sudden palm]

first time I have the same compatibility on two MiSter and everything works the same , except IS2 and Barkley

[mental briar]

What is the checksum of your 1mb cybermorph?

#1055574003810578503 message

that is mine

oh shit, just got a seed to load it

lets see if it loads everything else 😄

[sudden palm]

81dc55f1abaa89f4b3d510cb4c2e5fe8

same as yours

[mental briar]

so this is real weird

if cybermorph is the FIRST game I load, it loads fine

but I can’t load it after loading AVP

[sudden palm]

let;s see

[mental briar]

testing some more to make sure that’s reproducible

yeah, if I load the rom and reboot the core, it loads fine

but if I load AVP and then load cybermorph, it doesn’t work

[sudden palm]

for me it does not matter, it works every time

[mental briar]

the 1mb cybermorph?

[sudden palm]

yes

[mental briar]

weirdddddd

kuba, when you’re making builds of this, do you ever not get the timing warning?

its my first core, so i dunno what’s normal when it builds

[sudden palm]

with this core , it is not possible that there is no warning

you can only get worse or better results

[mental briar]

breaks my brain

Yup, fucking weird. all 13 load cybermorph rev b no problem

but if I load AVP and then cybermorph, no dice

[sudden palm]

I have checked several demoscene productions , all work well

nice to have jag core ❤️

[pallid gulch]

with the build 01/08/2025, ASVP have sound but no picture. It is ok with previous build 01/05

[mental briar]

Try one of these #1055574003810578503 message

[pallid gulch]

thank you I will keep 01/05 and 01/08 for the moment ^^

[mental briar]

Oooo, what’s in the new build, grey?!

[tropic rock]

Check the title

[mental briar]

Oh shit!

[swift breach]

Is this first single ram build?

[mental briar]

You madman

[tropic rock]

https://github.com/greyrogue/Jaguar_MiSTer/commit/7d7b92bf9e19c2e29083aeda96ce76222c8fc5a4

(Untested is no longer true)

[spare idol]

Is the above Single only available uncompiled? thanks.

[tropic rock]

#test-builds message

[spare idol]

Thanking thee!

[mental briar]

sound but no video in AVP on my qmtech stack. I am already cooking builds for folks

[swift breach]

How far can this single sdram build go tho

[tropic rock]

AvP works on mine

[swift breach]

Or at least, what are estimated limits?

I'm still debating if to get a new SD RAM stick for this core for full compatability in the future

[mental briar]

@thorny swift Single Ram just dropped

[thorny swift]

Oh wow

[keen zealot]

Just wow.

[tropic rock]

Section running with several sdram accesses

[mental briar]

No Fight for Life or AVP for me

[tropic rock]

Each square pulse is 4 clocks long. If the current bank of 2048 bytes is the same as the last access, hardware should take 2 pulses to read.

The single ram access requires 3 pulses

I commandeered 256KB of BRAM to use in place of SDRAM in single mode. This allows 1/4 of the address space to work at 2 pulses speed like dual sdram. If the BIOS were moved to the SDRAM it might be possible to cover another 1/4, but that might make the build less stable as it would be using a large percentage of bram

The 3 pulses speed is only a problem for reads. Writes happen at the required 2 pulse speed

[thorny swift]

Thanks for waiting til after the vid 🤣 unintentionally of course. Makes my life much easier

[tropic rock]

The net affect of running slow can be pretty much anything: slowdown, screen tearing, graphics glitches, crashing, or no difference

[mental briar]

takes longer to build too, it seems. amazing work, grey

[tropic rock]

But again, it should be running as well or better than builds based on January 5 or earlier. (Just missing the speed fix on January 8 that lets it match real hardware for all sdram access)

(Also not counting build instability)

[brittle zinc]

Picked a good time to untangle my mess of DV cables 🙂

[brittle zinc]

Just means it's trying harder

[mental briar]

effort

[mental briar]

wish quartus had a mac client. my m4 pro mini would love to compile this

gonna be a little bit before I have a handful of single ram cores for folks having trouble loading games

[spare idol]

Lay question:are any of the recently available AI's viable/useful in refining these FPGA cores?

[still aurora]

AI is a useful idiot

[uncut atlas]

not particularly, in my experience

[tropic rock]

Kitrinx actually tried that while we were trying to reduce the slacks on a piece of code I was manually trying things on

I seem to recall some were broke and the rest made it worse

[uncut atlas]

it tended to obliterate nessesary nuance in the behavior

[dusk slate]

Someone should port Wizardry to the Jaguar so it can be played on this single-ram wizardry.

[mental briar]

https://tenor.com/s1yE0FCvsqJ.gif

[spare idol]

Seems like the same problem with diapraxis that skips presups, it's a matter of time before the foundations crack.lol

[brittle zinc]

It's useful sometimes as a sanity check for a code snippet or at least to open your eyes to a new path but otherwise it does more harm than good. It certainly can't do it for you

[tranquil cape]

Single RAM v2.5 user here. Just tried and I can only hear the Club Drive theme with a black screen, so the core is perfect!

But seriously awesome work!❤️

[uncut atlas]

I used it to catch a typo once

that's about the extent of my good experiences

its helpful sometimes to interpret datasheets

it cant take all the lingo and break it down for you

[spare idol]

So there's no Danger of devs being made redundant anytime soon? lol

[brittle zinc]

I'd definitely not take it's word for that 😂

[still aurora]

I had an enjoyable 10 mins when the AI suggested a code improvement, that broke the code. I explained it to the AI. it said I was right I asked it to go again and it did the excat same thing

[uncut atlas]

I would say not good devs

[uncut atlas]

no, very grain of salt

it halucinates a lot

[spare idol]

Go home Computer, you're drunk! lol

[still aurora]

Its amusing though that i see on code review clear ChatGpt code

still if it works and is reasonable I cant fail the reviews

[brittle zinc]

It takes the shortest possible path and mostly ignores what you ask. The fact people use the code it generates blindly is insane

[still aurora]

yep by all means use it to start but for god sake check what its doing

[mental briar]

I was trying to use it to set up a downloader script for my kid's mister (the documentation says to use !'s but then it also shows !!s which made it confusing). I told chatgpt what I wanted to do and it generated something that I knew was not correct.

"I think you forgot to add the exclamation points"

"You're right, TheJesusFish! Here is your updated code"

And then, I shit you not, it just put exclamation marks at the end of each line of code...so then the script was just yelling at me

I stopped using it for anything serious after that.

[tranquil cape]

This is awesome

[still aurora]

Tempest 2k is the best Jag game

All hail Minter

[spare idol]

Did CHATGPT build that minisub that imploded? 🤣

[still aurora]

only the controller !

[spare idol]

lol

[brittle zinc]

Yes

[brittle zinc]

Just the HID protocol

[still aurora]

chatgpt I have stubbed the emergency surface code. Add it if needed

[mental briar]

chatgpt made some changes to the sub and now every time I plug in this gravis gamepad it loads magic carpet instead of letting me control the sub

no big deal though, who wants to see the titanic!?

[hidden siren]

oooh, thanks for the single sdram build! I just this afternoon decided to put my mister pi into it's case, with a single ram as I have no means of audio out with just HDMI in my current setup, so this an excellent birthday gift for me 🙂 Thakns!

[mental briar]

happy birthday 🙂

[rotund portal]

That's... very clever.

[rotund portal]

Possibly some register(s) aren't being reset properly? I can't imagine it would be a problem with it seeing some leftover ROM stuff in DDR.

[mental briar]

What’s weird is that it’s not happening to kuba. I dunno, my brain hurts

[hidden siren]

Thank you!!

[rotund portal]

Anyone have a new RBF yet? I'm doing constant Quartus compiles for other stuff atm. lol

And I'm lazy.

Oh, test builds.

Thanks, @tropic rock and @uncut atlas

Oww. AvP black screen, for me.

[hidden siren]

lol. First thing I tried was rayman. It has been very VERY long since I had seen the intro of it. During the intro I thought - hm, maybe a glitch on the combo of my mister and this build, as rayman has no head. Sight. Then the intro continued....

I felt dumb and silly 🙂

[uncut atlas]

well you're using a Jaguar, the rest of us feel dumb and silly too

[hidden siren]

... I also own a real one still, so not sure what that says about me 🙂

[rotund portal]

I don't think MiSTer will ever quite reach the pinnacle of FPGA retro gaming... until we can get the Casio Loopy printer hooked up.

[mental briar]

I'm cooking builds right meow

[rotund portal]

Music in Pinball Fantasies is still awesome.

I'm also cooking a build... for... other reasons.

[hidden blade]

The new single SD Ram version works very good so far. Tested a few games. But AvP indeed not. Black screen, and music/sfx playing in the background.

[sacred narwhal]

MiSTer Multisystem build here, and i've only been able to get as far as either the BIOS looping itself or the game booting/freezing into a black screen; not sure what version of SDRAM my board has, though i do know i ordered the MMS back in Nov 2021

[hidden blade]

Make sure you use .j64 versions, not .rom. Same for the Bios.

No-Intro Rom Set

[sacred narwhal]

the bios definitely works at least! i know that was the .j64 version

[hidden blade]

Had the same problem. Bios and Roms in .j64 format fixed it for me at least.

Some games are still not working properly, like Dragon - The Bruce Lee Story, Barkleys Shut up and Jam, or Iron Soldier 2. But the games that work are running fine in full speed as it seems.

[mental briar]

Here are 7 builds folks can try. I'm going to build 8 more, but this should get you going (i'll delete this after I have the rest of the builds done)

[void quartz]

Can someone grant me access to Grey's core so I can join the test party?

[hidden blade]

https://discord.com/channels/647909397477195803/737506076806611064

[void quartz]

How do I get past the 'No Access'?

[hidden blade]

Huh, never had such an issue.

[sacred narwhal]

thanks! everything it working as it should now

[void quartz]

Got it figured out...had to change my role to 'I want it All' and then I could see the channel's full content. Thanks.

[mental briar]

if you're having trouble lading any games on the single ram core, you can try these alternative builds here: #1055574003810578503 message

[brittle zinc]

You must have a decent machine 😂

[ashen spoke]

WOW we have a single ram build of Saturn?

[mental briar]

yes robby, it’s in update all

[ashen spoke]

What seriously

Oh uhh

I meant Jaguar

[hidden siren]

Been playing it for a bit, for me, AVP works with av (hdmi output), as does club drive, but fight for life crashes as it enters combat. Flip something did not get past the startscreen. Super impressive, this. Very cool. Much appreciated, thanks!!

[tranquil cape]

I am very surprised that most games work on my old single MiSTer Addons v2.5 ram, but I think I got lucky since I never had any Saturn issues (including Grandia textures (even with a Samsung EVO sd card))

AVP, Club Drive, and FfL don't work, but everything else has loaded up

[mental briar]

Did you try one of these builds: #1055574003810578503 message

[mental briar]

~13 min build

I wish there was a way to automate this

[tranquil cape]

nope, but I will - thanks!

[brittle zinc]

Pretty much same here. FFL starts combat and crashes shortly after. But I'll say this, the speed I'm getting (with turbo on) is on par I think with the last accurate SDRAM timing core. I use the high score screen web rotation on T2K as a milestone and it's looking good to me @tropic rock

AvP works great. The 32mb ram is going in the drawer possibly to live out it's days

[void quartz]

I figured out the issue...you have to use the No-Intro ROMs

[tranquil cape]

number 03 is a good one! Fight for Life crashed once, but worked OK after a reload. Dragon working good too!
Some more testing and everything has worked that I've thrown at it. Any glitches or crashes get ironed out after a reload

[regal tapir]

AVP and Club Drive works on build 04, with some grafical glitches on the menu. In game works fine. Dragon Bruce Lee also works, but with grafical glitch on the background. This is getting too much good!

[hidden blade]

Nice, thanks for testing

[mental briar]

I’m, cooking up another 3 or 4 builds. Then I’ll post 2 packs, one for dual ram and one for single - there should be a good build for most folks in there

[ashen spoke]

It’s a build buffet!

[mental briar]

I AM A DEVELOPER NOW

[hidden blade]

Oh Jesus!

[ashen spoke]

[tranquil cape]

THESE GAMES SUCK - I LOVE THEM! ||jk - there is some awesome stuff here, but I really like the bad ones too||

[mental briar]

I can push the play button in quartus and wait 13 minutes for a build.

[hidden blade]

Bob the Builder

[mental briar]

i'll just stand on Grey's shoulders here

[serene widget]

Robby, you're tired. Go to bed.

[tranquil cape]

Wow - Iron Soldier is cool

[mental briar]

Ok, here is your Core Buffet. If you're having trouble loading any games in either the single or dual ram cores, try one of these.

You can just unzip these into /media/fat and it will create a directory that has the test cores in it. Will be on the top of your MiSTer menu

[grizzled bloom]

Build 08 seems to work best for me. Avp, fight for life, club drive all boot.

Does iron soldier 2 work for anyone?

[mental briar]

No. So far we haven’t seen any builds that boot iron soldier 2 or shut up and jam

[grizzled bloom]

Has anybody beaten any games on these cores yet? I’m thinking of playing through Atari karts… for science

[mental briar]

I started an avp playthrough last night

Now that we can save 🙂

[ashen spoke]

I’ve been slowly starting to appreciate AvP

Gotta put myself in the right mindset.

Like DOOM for SNES hadn’t even come out yet and the Saturn/PS1 was still a year away.

Considering all that and ignoring PC, game is pretty impressive.

[mental briar]

For the time, it was pretty wild

[grizzled bloom]

I find snes doom hard to appreciate in any era

Except from a technical aspect

[thorny swift]

It’s a well made game. It has atmosphere. Challenge. Bit of an anxiety inducing vibe. Interesting “soundtrack”

Dev story comes with a metric crap ton of controversy and weirdness but oh well

[ashen spoke]

Oh that’s bad

[grizzled bloom]

It must have been the best console fps at that moment in time. Better than anything on 3do if memory serves

[thorny swift]

Yes. Jane Whitaker has told some very interesting tales about their work on it. And on 3DO M2. And their history in gaming

They went by a diff name back then but I want to avoid deadnaming them as they go by Jane now

[ashen spoke]

Yeah I think you’re right. I think Genesis has Zero Tolerance which came out the same year,

[grizzled bloom]

3do and jag had pretty good versions of Wolfenstein

And I like escape from monster manor a lot, but Avp has a more next gen feel compared to any of those

I can’t get into jag doom, even when I owned it. I have a hard time when a game doesn’t have any music at all. Like at least Avp has a soundscape.

[ashen spoke]

I like all versions of DOOM because I am a crazy man lol

There were work reasons too but mainly the crazy

[grizzled bloom]

I played through it once but the lack of soundtrack pulled me out of it

[ashen spoke]

Yeah, that’s a big downgrade for sure

[grizzled bloom]

But I guess it’s better than having bad music I suppose

[ivory basin]

@mental briar you son of a bit*h! The first Dual RAM one finally loaded AVP for me

First time on my MiSTer Pi

[grizzled bloom]

It’s a good podcast game

[ashen spoke]

Yeah I gotta try those builds. So I can give AvP another shot

[ivory basin]

And Bubsy loads too, damn! It's like Second Christmas

[mental briar]

[ivory basin]

Very excited to start testing this core!

[grizzled bloom]

Played through all the courses on beginner in Atari Karts. There’s 3 other difficulties higher though. So I’ll probably slog through those too.

6/10 kart racer was hoping to like it a bit more.

Game worked fine, some minor graphic glitches that sporadically appear in the middle of the screen where the track meets the horizon.

[rotund portal]

Latest single-SDRAM core seems quite stable, so far.

I compiled from source, too.

I'm gonna try not to touch the Quartus settings. lol

[minor solstice]

Kinda looking forward to the Single Ram build. That way I can put my analog daughter board back in. Err wait did CDI require dual ram? If not i could rock single ram on all cores I think

[mental briar]

nope, cdi is single ram

single ram a little more unstable for me. can't get fight for life to load on any of the 15 builds

[minor solstice]

Well regardless, I use HDMI more than analog video, so its not a huge deal but would be nice to have the flexability

[rotund portal]

No, it doesn't load anything yet. lol

That was simply patching the CD BIOS, to make the main BIOS read it as 32-bit wide.

(as that's how it gets loaded into SDRAM on the core atm. The actual CD BIOS chip is only 8-bit wide, so the cart header needed a tweak.)

https://cdn.discordapp.com/attachments/1315008851874938948/1328219421495263262/image.png?ex=6785e83b&is=678496bb&hm=ef267a85e5e1647bad5310a7c66d7cd0719a492a78deda86b426aeab739a4003&

Just change those four bytes (in red) from all 00, to all 04.

As long as the CD BIOS filename then has the extension .ROM, .BIN, or .J64, it should show up in the MiSTer file browser.

Then you can load it as if it's a "cart".

But yeah, nothing else happening with it yet, just Jeff Minter's fancy visual display.

You have to enable the Cart Checksum Patch option, too. Not sure where the checksum is in the cart header.

Oh, I should probably mention - I do have some Butch (CD drive chip) registers in the core atm.

So not sure if the CD BIOS will still "boot" on the virgin core.

OK, I tried the (patched) CD BIOS on the latest RBF, and it still boots.

Again, not too useful atm, just for fun.

[uncut atlas]

[fickle folio]

What % hope are we placing in a single SDRAM full-speed Jaguar implementation?

Asking for a friend

[marble holly]

69%

[sterile moss]

Nice

[frosty pike]

Funny answer...but honestly, throwing spaghetti at the wall

That's probably pretty accurate

[warm oasis]

Great work Ash getting the Jag CD BIOS booting, that is cool to see.

Does anyone know if Atari open sourced the Jag CD and BIOS the way they did the Jaguar?

[pure bridge]

I think it was Hasbro who did the open sourcing. And I assume they included everything Jaguar related. (Or rather didn't exclude anything.)

[rotund portal]

Something like this...

//assign cart_q1 = (!abus_out[2]) ? DDRAM_DOUT[63:32] : DDRAM_DOUT[31:00];
assign cart_q1 = (abus_out[22:0]>=23'h00400 && abus_out[22:0]<=23'h00403 && status[17]) ? 32'h04040404 :     // Patch the Cart ROM, to force reading as 32-bit wide.
                                            (!abus_out[2]) ? DDRAM_DOUT[63:32] : DDRAM_DOUT[31:00];        // Allow reading of Cart data (as 32-bit wide).

Maybe a bit more human-readable...

wire cart_patch_32_cs = ({abus_out[22:2],2'b00}==23'h00400 && status[17]);  // Patch 0x400-0x403.

wire [31:0] cart_read_32 = (!abus_out[2]) ? DDRAM_DOUT[63:32] : DDRAM_DOUT[31:00];

//assign cart_q1 = (!abus_out[2]) ? DDRAM_DOUT[63:32] : DDRAM_DOUT[31:00];
assign cart_q1 = cart_patch_32_cs ? 32'h04040404 :     // Patch the Cart ROM, to force reading as 32-bit wide.
                                    cart_read_32;    // Allow reading of Cart data (as 32-bit wide).

If it wasn't for Discord, wrapping the text

"OH,Patch Cart reading 32-bit,Off,On;",

Slight tweak...

wire cart_patch_32_cs    = (abus_out[23:0]>=24'h800400 && abus_out[23:0]<=24'h800403 && status[17]);  // Patch 0x400-0x403.

'cos the Cart ROM is mapped starting from 0x800000.

But can go up to 0xDFFFFF.

So the way I was decoding the bits originally wouldn't have worked properly.

It would have been stomping on other Cart data.

Now it looks at a full 24-bits of address, to patch only 0x800400 to 0x800403.

(anything higher than 0xDFFFFF wouldn't decode to the Cart range anyway, in theory.)

Would still to enable the Cart checksum Patch as well, for the Jag CD thing.

Unless somebody can find the info on the Jag cart header, and how to re-calculate the checksum.

[warm oasis]

Cool, would be good if there was a way to confirm this but guess we can operate under the assumption it is unless someone comes along and tells us otherwise.

If I understand right the source code for the Jag BIOS was released, so it could be compiled (and someone added MiSTer Kun image). Is source code for Jag CD BIOS released as well?

[rotund portal]

Yep. I was showing it earlier.

I went from not finding much at all, to finding the motherload. lol

On the same Facebook group I found stuff years ago.

There's also a thread on Atariage, with the source code for quite a few games, including Where Did YOU Learn To Fly?

Oh, I thought I was in the other channel.

Compiling now, to test the new ROM patch option.

The source for Tempest 2000, was actually what helped me get sound working in more games in the core, way back when.

It had a counter thingy for the I2S block, which was out-of-sync with another counter.

So it was often missing the trigger to grab the new audio sample(s) from the core.

    "O2,Cart Checksum Patch,Off,On;",
    "OH,Patch Cart reading 32-bit,Off,On;",

Hard to know how to name the menu option, without taking up too many chars.

The checksum thing patches ONE instruction in the main BIOS, to bypass the error if the cart checksum fails.

The cart reading 32-bit thing, patches those four bytes in the Cart ROM, to force reading it as 32-bit wide.

(which changes how the Tom chip increments the address bits. The 68K won't really notice the difference, AFAIK.)

[serene widget]

Imagine if some crazy person hacked the game, just to optimize it and improve the controls.

[south locust]

what a good news that this core is coming to single ram

i tested the test build and i could play tempest 2000, so happy

there are games that don't boot, like AvP, I suppose it's reported.

[keen zealot]

I've tested the Single RAM builds on my Mister Pi.

The best results are build 05 and 06, build 01 and 07 refused to boot AvP at all, and the other ones failed on video but only sound (02-03-04).

Build 06 seems a little bit faster (Club Drive, Fight for Life work too on it).

So I'm keeping that build.

[ashen spoke]

Thanks for reporting in!

I need to skim through chat to see what dual ram build worked for people.

[waxen bough]

I see this core getting good recently

[serene widget]

I hope that, by this year, whether it's single-ram or dual-ram, the Jaguar core reaches the same quality as BigPEmu.

[timid snow]

Making excellent progress so far!

[urban mango]

Its likely to be different for different folks though isn't it?

[mental briar]

It is

[upper lodge]

I'm excited about the progress being made if only because then more folks can try out Ultra Vortek, the oddly pretty good jaguar fighting game

[ashen spoke]

what really

[unreal siren]

Thx for the Single build, amzing stuff!!
all games Ive tried works great!?
AvP,Doom,Wolf3d and rayman.
I dont even perceive the performance to be bad?!

[south locust]

which build ? AvP doesn't work for me, only sound.

[unreal siren]

Grabbed the one from the test -build channel

[mental briar]

Try the builds in the single ram zip: #1055574003810578503 message

[waxen bough]

Does this need any setup?

Ahn bios

I see

[mental briar]

yeah, but I think the bios is in the channel

because it’s open source

ooo it’s even pinned

[waxen bough]

I already had it nvm

AvP works for me on Single SDRAM on #test-builds

[thorny swift]

is there a reason Dual Ram core sees all my game files but single ram core sees nothing? same folder, diff result

wait I reloaded again and they appear

well that is weird

just loaded the DUAL core, then went back to the single core and it was all there

[thorny swift]

sometimes it truly is

ok well its running and capturing now so

[mental briar]

The single ram core is definitely more finicky than the already finicky dual ram core

[thorny swift]

I am always impressed by a purely digital device producing such oddly organic results

[mental briar]

Breaks my brain

I compiled 15 single ram cores yesterday. All of them were different sizes

Breaks my brain

[thorny swift]

the world may never know

[keen zealot]

Build 06 on Single and Build 08 on Dual are the best results for me, in terms of speeds and compatibility.

"Your mileage may vary."

[thorny swift]

AvP has just gone audio no image on two of the cores

but I am not hunting too much to find a working one...just notating in video form it may be less likely to boot

Fight for Life is the same...character select then done for

testing Skyhammer next

that always feels like a heavy hitter hardware wise

works

[tranquil cape]

#3 from this worked with everthing for me(some games needed the rom reloaded)
#1055574003810578503 message

Still need to try out the builds from later that night though

[uncut atlas]

probably a typical compromised single stick full-functionality dual ram situation like saturn

we'll see

[ashen spoke]

In core devs we trust 🫡

[dusk slate]

That's because much like Johnny 5, MiSTer is alive!

[waxen terrace]

Just out of curiosity is saving disabled on the Single Ram cores? The options are greyed out for me

Ohh wait now they are not, only whilst AvP was running

[keen zealot]

It does work, I've played Rayman and saved without any issues.

[waxen terrace]

yeah I got it working now, it was just strange that they were greyed out whilst I was in game in AvP, just to let people know I was using build 8 for AvP, Fight for Life is a no go, got passed character select, showed arena then went black

[rotund portal]

Genuinely don't think I've ever seen that happen. Haunted. lol

And I've owned at least six DE10 boards, with different SD cards, and mismatched SDRAM modules.

The menu stuff is pretty much all handled by the main MiSTer process on the ARM.

It's possible that a core could have marginal timings which could affect the communication between the ARM and FPGA side maybe.

But that would generally cause a problem with the overall OSD appearance, not just the file browser.

Hopefully just a random glitch. Cosmic Rays, Space Bats, etc.

[thorny swift]

yeah I couldnt repeat it so just ghosts in the code

[glad flame]

When in doubt, just blame the sun having one of it's plasma attacks.

[thorny swift]

I even backed out of the folder, confirmed I was in the Jaguar folder, entered back into the folder...one rom...Rayman beta. Quit, launched dual ram core, all files intact...relaunched single ram...all files intact. Rebooted single ram to confirm I hadnt just hit dual ram twice...all good to go

[mental briar]

Local files?

[thorny swift]

yep. MicroSD

I am sure its just core weirdness

[mental briar]

Computers 🤷

[thorny swift]

after that I went and fought Sound Blaster IRQ in DOS so yeah...one of those days

[rotund portal]

SET BLASTER=A220 I5 D1 T6

[shadow trail]

never tried out the jaguar core until today but things seem quite playable on single ram, curious how much of a performance increase fullspeed will be

[grizzled bloom]

Tried Trevor Mcfur and it seems crazy to me that Atari released a shmup without music. If it isn’t like a space invaders/galaga era shooter it should really have music. Comes off really cheap.

I am liking most of the other stuff I’m playing though. Single ram seems to work really well.

Actually any game of any genre in that era that didn’t have a soundtrack (jaguar is the most guilty of this I think) it makes it feel more dated than it actually is. Games like Avp had atmosphere and that’s awesome, I’m talking about when the game is just completely silent. Like it starts feeling like 7800 game or something.

Zero 5 is completely insane. I think I like it.

[hidden siren]

So, playing Wolfenstein again - loved it as one of the few versions that had a flamethrower 🙂 on grey's single ram version, and i noticed the stereo channels are reversed ; a door closing on the left of me, sounds like it's closing on the right. On BigPEmu it does sound correct. A quick search does not reveal that it's supposed to be reversed - so: is this an issue with the core? I am using the analog(minijack) out

and an hdmi (well, dvi) screen

[deft spruce]

no luck on the singleram core with any configuration but ill be patient; im very excited for this core to come along

is the bios supposed to be named anything particular or in any particular directory?

[flat glade]

Same on my end currently. MiSTer Pi, FWIW.

Edit: Nevermind, I can get into game on a couple of the pinned cores. Looks like version 7 is the least glitchy for me. AVP displays perfectly as far as I can tell.

[hidden siren]

Also, i'm struggling to map the numpad in addition to my controller ; when choosing Define Jaguar buttons in the ui, whilst using a PS5/Dual sense controller, I skip the definitons of 1-0, star and hash, as I dont 'want' them on the controller. But then, I don't know how to define it on the KB. I can't define them on the keyboard when I pick yes on the question Do you want to setup alternative buttons?, for example. I tried searching in the channel, but that didn't reveal much. Any suggestions would be appreciated!

[hidden siren]

yes, bios.rom in the games/Jaguar folder

Also, ensure that you have the correct type of roms. See the pinned messages

(works great on my misterpi, btw)

[deft spruce]

that worked buddy thank you

i had to load bios manually but i am in game now

bubsy is now mine

[tranquil cape]

bios loaded automatically for me as boot.rom

[south locust]

I tested singlerework 15 and AvP works

[ivory basin]

I was able to get the Jaguar pinball game loaded up, but then I realized I don't have a Jaguar pad (I remain un-cursed) so I couldn't select a table since it used the keypad for that 😦

[tranquil cape]

If you have a Sony style controller with dual analog you can map the number buttons to the sticks and L3 R3

[ivory basin]

oh that's a great idea

I'm using a Xbox 360 controller since I have like 8 of them and the USB receiver

I'll get that set up tonight!

[hidden siren]

Will give that a go later too!

Thanks!

(oh, and for those who don't have a controller handy, the controller is numbered like a phone (1-9, * 0 # from top left to bottom right), whilst a numpad on a keyboard is not..)

Huh. TIL that robby's favorite store, the one who sells all those inserts, also in the past has created and sold (now sold out) a replica of the pro controller. Source:
https://www.youtube.com/watch?v=sXZduIBMUWQ
https://forums.atariage.com/topic/271862-brand-new-atari-jaguar-pro-controllers-for-sale/

Fun that it's the same guy/company 🙂

[mental briar]

I really don't think the pro controller is helpful tho. No 6 button fighters. the games were designed with the keypad in mind

although, TIL, if you hold A in AVP you can strafe left and right

Who needs 7 and 9!

[hidden siren]

no, same, but apparently, enough ppl want one

[mental briar]

I mean, I'd buy one if they were the same price

but I make poor financial decisions

[ashen spoke]

The pro controller is cool but I like the original requires the keypad for some games

I value the novelty more than accessibility for Jaguar but that’s not a sane take

[mental briar]

oh yeah, that controller is not about accessibility at all

that controller is the epitome of “you were too preoccupied with whether or not you could, you didn’t consider if you should” energy

[ashen spoke]

I want to build a controller with leds or displays in the buttons

[mental briar]

https://tenor.com/IeFy.gif

[ashen spoke]

Well yeah I mean I can’t argue that. But like a controller that’s versatile for retro gaming. Where the buttons display the inputs for each console

but yeah that’s a novelty with an insanely high price tag lol

[tranquil cape]

Trackball, knob and numpad!

[pseudo salmon]

I've always imagined/dreamed of the controller you're describing. Where each button visually changes to fit the console it's currently being used to play, right? That would be epic.

[ashen spoke]

Yeah! Glad to hear I’m not the only one who would see value in it. 🍻

[ashen spoke]

Thanks dude! I forgot which one worked for me but it worked and AvP, FFL, Club Drive are all playing wonderfully. 🍻

[mental briar]

I want the arcade stick they announced

[regal tapir]

Some of my tests on Single Ram Build 09. It works great, just a few games don't work on any build, like WHite Man Can't Jump, Iron Soldier 2.

https://youtu.be/9Z8o2jK79KQ

[ashen spoke]

I think those games consistently don’t work for anyone.

[mental briar]

yeah, I'm pretty sure white men can't jump is another one that doesn't work

[hidden blade]

White Men can't jump works fine for me with the current test core (single SD Ram). I'm using No-Intro j.64 roms and the "Mister" Bios version.

[mental briar]

Oh interesting. I haven’t actually tested it in a while. I’ll check it out

Barkleys shut up and jam and iron soldier 2 are the for sure no boots

[hidden blade]

Yep

[shadow trail]

Alien Syndrome didn't boot for me, which appears to be a homebrew conversion from atari st

[regal tapir]

Thanks, it works here too.

[deft spruce]

i know that jag emulation has been playable for some years now but as an old timer i must say once this is available on analog out its going to be like child-me won the lottery, thank you to any and all devs working on this

[grizzled bloom]

I wish Barkley’s shut up and jam gaiden: the hoops saga was on the jaguar

[pure bridge]

What does the "CPU Speed" option affect? Just the 68K? The GPU and DSP as well? All the system clocks?

[south locust]

Where did you learn to fly

[glad flame]

I question the location that you've obtained the knowledge of aviation.

[verbal coyote]

This is using a CRT with the single SDram core?

[south locust]

Yes

[verbal coyote]

Ok great! I wasn't able to get any signal using IO board 6.1

I have to double check the INI settings

I'm missing something

[mental briar]

Jaguar day again so soon!

[tranquil cape]

YO - I can get White Men Can't Jump to load on single ram
(but not Iron Soldier 2)

[ashen spoke]

I don’t know if you’re lucky or cursed lol

[uncut atlas]

why not both

[tropic rock]

Iron Soldier 2 makes it to the menu if I turn on turbo (but crashes when selecting game start)

[remote pecan]

Dual ram - this game is working for me as well.

[mental briar]

yeah, I was confusing white men and shut up and jam. it's shut up and jam that doesn't load

[remote pecan]

Arena Football '95 keeps hanging up after a few seconds in a match.

[south locust]

this console has a lot of ugly games

but tempest 2000 is awesome

[tranquil cape]

the Jaguar version of Wolfenstein 3D is really cool. Very unique

[south locust]

yes, it is

3do version and MacOs very good too

[upper abyss]

lol just got slightly startled by the core growling at me upon boot !

[uncut atlas]

I am inappropriately pleased by the mister-kun version of the bios

[upper abyss]

Word!

Well I finally got around to setting the latest unstable up ! Time to jagoff!!

[tranquil cape]

this new single ram test build seems very stable so far (and I'm on old v2.5 ram)
aside from Iron Soldier 2, every retail release is working great

[upper abyss]

Atari karts is exactly the kind of jank I’m looking for .. moving on to fighting game jank in a few

[mental briar]

Dual core seems real good on my mister pi. hasn't failed to load anything yet (I still need to reboot the core to get cybermorph to load, but it works)

Single ram seems real stable too, Grey. Really nice work

I started cooking builds as soon as this dropped...but we will see if we even need them...

[tropic rock]

I think I found and fixed the issue with instability. I isolated the root cause on Power Drive Rally and it likely fixed AvP and TMcF as well. Possibly other things too.

[royal cloud]

i thought that name of the game is sarcasm, when i watched avgn episode about jaguar

[tropic rock]

Although my change is forcing an undefined behavior in the netlists to one defined behavior, so it is hard to draw a firm conclusion

[sudden palm]

latest dualsdram test core works great !

[mental briar]

Is dual ram still faster?

[verbal coyote]

Avp runs at full speed now?

[mental briar]

its probably close on dual ram

[fallow salmon]

awesome !

[tropic rock]

Dual ram is still faster

[fallow salmon]

if you have a minute to write about it, what was the issue?

[tropic rock]

The registers are dual port, which means it can be accessed simultaneously by two different interfaces.
It can try and write different values to the same register at the same time
I dont think individual opcodes have the issue, but pipelining/scoreboarding can delay writes so they overlap
It was something like this
LOAD (R30),R31
MOVEI #00004018,R31
and r31 was being written at the same time (the first operation writes a value it reads from memory; the second writes an immediate value)
Because the first operation takes longer, they both try and write register-31 at the same time with different values.
Not sure why the first operation was being done at all, as it is overwritten without being read.

I changed it to write the second one.

[fallow salmon]

huh

i wonder if the same bug existed on real hardware but was concealed by consistent favorable timings in the actual chip

[tropic rock]

https://github.com/greyrogue/Jaguar_MiSTer/commit/c1389c22e83d736d677f9e230768add5fe617716#diff-9f1958c03c40037686b39ca64e04c2a6d13951bf6ffe6ec5687a0fba473120e6L52

[fallow salmon]

thanks thats really interesting

[tropic rock]

That is my assumption. And presumably it worked across three hardware revs of the chip

[upper abyss]

Jaguar port of cannon fodder is actually pretty good!

[sudden palm]

works great on three de10 nano , I'm glad I don't have to compile 16 cores anymore 😄 thanks @tropic rock 🍻

[uncut atlas]

it makes me wonder if avp working was a timing failure not success

it was effectively illogical behavior so probably it relied on extremely tiny differences in continuous logic to work

[tropic rock]

I guess it is possible the primitive they used for ram defined behavior for simultaneous writes to use channel b over channel a. Would need documentation on toshiba and motorola primitives to check.

[pure bridge]

I think this may be a known bug. "In any instruction where the destination register is written to without being read, the destination register will not be protected by the score-boarding mechanism of the GPU/DSP. This includes MTOI, MORMI, RESMAC, all MOVE variations, and all LOAD variations."

[gritty kestrel]

Many thanks to all professionals who delight us with their developments! The atari jaguar core is simply magnificent, I have never had such a console and I have not even heard of it, I have already tried the core on mister and everything is fine, the saves work, through YC too, I am very happy! If only the 3DO core would appear someday, my happiness would know no bounds! Thank you...👍

[tropic rock]

Yep, but apparently some games do it anyway and got lucky

[uncut atlas]

3do is what gets you boundless happiness? really?

[gritty kestrel]

If 3docore was on Mister, I would be very happy) I had this console as a child

[grim ferry]

100% I'm a huge 3DO fan!

[grim ferry]

Interestingly, for me the new Test build does the opposite as the previous one. Now I do get video on AvP but no sound. Previously it was the opposite.

[fallow salmon]

didn't we used to have a 3DNo sticker

the first step to getting a core made is getting a sticker about how its impossible. this is how we got an n64 core

[ashen spoke]

Sorry everyone, we had a development meeting on which future cores to work on and I very sternly disallowed the 3DO core.

I have a grudge against 3DO ever since Trip Hawkins cut me off at the taxi stand and stole my taxi.

[gritty kestrel]

On the contrary, we need to create a core and beat it to the point of holes, to spite it!

[gritty kestrel]

in this case it turns out that Trip Hawkins won

[brittle zinc]

Works gangbusters. The only game so far that failed is the perennial iron solder 2. Everything else is perfect

[ashen spoke]

That dumb joke is actually based on a true story. My friend was waiting for a cab at GDC and when it pulled up. Peter Moleyneux of all people, rushed ahead of him and got into the cab and said "SORRY, MATE" as he was closing the door. lmao

It's ok, we got the last laugh. We would go to parties and say our name was Peter Molyneux and when they asked for ID I told 'em it was a passport and I left it back at the hotel. ALWAYS WORKED.

..for the three times I did it...

[brittle zinc]

He always struck me as a bit of a dick

[ashen spoke]

I don't know but that was a dick move lol.

which was a constant source of clowning on my friend lol

[fallow salmon]

that whole saga with that curiosity game kind of ruined him for me

the person who won that got fucked over

[sudden palm]

Barkley works?

[brittle zinc]

Ah, yeah sorry fails after the licencing logo. All the usual suspects other than those two are fine though

[sudden palm]

Thanks for checking!

[mental briar]

I have been in meetings all morning. both builds looking ok? I have some single ram builds cooked if folks are having issues

[grim ferry]

I get video but no sound in AvP on dual ram build

[warm oasis]

Yes, I am sorry to report after my recent investigation, the 3DO is not able to play every type of Photo CD, so it has been deemed not suitable for development for the MiSTer platform.

[mental briar]

in the latest core?

from today?

[grim ferry]

Yeah

Test build

[mental briar]

ok, I shall cook some up then

I have only tested on one mister so far

[fallow salmon]

some people still having avp issues?

[mental briar]

i didn't on my mister pi, but I have one more meeting before I can test the others

[void quartz]

All the usual suspects appear to working during my testing using Jaguar_Rework_dualram_20250114.rbf

[hidden blade]

Ah, AvP works now with todays core. Nice!

Single SD Ram

[fallow salmon]

we need a "best of jaguar games" pin

anyone whose actually played the library got a top 10?

[still aurora]

There is just one Game Tempest 2K

thats the Jag game list thanks

[low dome]

I used to own a good amount of Jaguar libary. Here was my top 10:

1. Tempest 2000
2. AVP
3. Rayman
4. Iron Soldier
5. NBA Jam: TE
6. Flashback
7. Wolfenstein 3D
8. BattleSphere
9. Cannon Fodder
10. Super Burnout
    Bonus: Raiden

[mental briar]

I don't see Fight for Life on that list.....

[low dome]

It never grew on me, haha

[hidden blade]

Double Dragon V!

🤣

[mental briar]

For a lot of these games I just imagine 12 year old Fish walking out of Electronics Boutique excited to play my new game. Only to come home with White Men Can't Jump

luckily, my parents spared me from owning a jaguar

[low dome]

One game not on my list that I also like was Power Driver Rally. Here is a picture of my collection before I sold it (attached). There is some regret every time I see these pictures, but I needed to unload it. haha.

[hidden siren]

4! controllers! The CD drive too 🙂 Nice.

[low dome]

one thing I like about the CD drive is it can play CD-R games

[hidden blade]

More testing with todays core. Iron Soldier 2 starts, but black screen after pressing "Start Game". Power Drive Rally works fine now.

[mental briar]

I know the CD looks like a toilet, but there is something really appealing about the console shell itself

I love the way it looks

I wonder how much I could pay @tulip walrus to model a mister pi case after it

[grizzled bloom]

Has anybody ever watched the YouTube channel the leftover culture review? He had a series where he did jaguar reviews some years back. Unlike avgn and everybody else he’d talk about it with great fondness. Got me back into jaguar at the time.

[last crater]

Dental camera using the Jaguar casing

[dusk slate]

I'm still waiting for the dental camera core.

[last crater]

Same. Ash get on it

[mental briar]

don't tempt ash

[tulip walrus]

I don't think money can buy this.

[last crater]

I think he's used to doing ten projects at the same time

[upper lodge]

oh yeah, set it to turbo speed and it's a lot of fun

legitimately solid game

[low dome]

Don't forget the failed Coleco Chameleon, haha:

[last crater]

Why did you have to remind me 😅

[grizzled bloom]

https://youtu.be/iKR1XNsHKeU?si=s_vBIDZaao8f9Sjl

[mental briar]

it really is just a spray painted jag shell

[tulip walrus]

I should make a CD-i case.

[grizzled bloom]

Chameleon crawled so that Amico could run

[ivory basin]

Tommy Tallarico probably invented the Chameleon, too.

Remember When Play Again?

[grizzled bloom]

That slogan sounds like that moment when the dementia kicks in

[ivory basin]

It 100% does

[tranquil cape]

lol - the knock-off Wii U controller

[faint laurel]

Wth, Raiden is easily top 10 on the Jag whether you like shmups or not!

[grizzled bloom]

Everybody knows the Wii u had the ultimate controller for retro games of course. That’s why they picked it clearly.

It’s not like the dpad and face buttons are squished down in the middle out of sight or anything.

[low dome]

it was definitely a good port of Raiden. Probably the best cart port of its generation.

[faint laurel]

I see you added it as a bonus to the list, you are forgiven 🙂

absolutely one of the best versions, put 200+ hours in it back in the day..

[mental briar]

Has anyone aside from @grim ferry had trouble with this morning's build?

[tranquil cape]

I've had to reload roms a couple of times, but aside from that it's been great

[grim ferry]

That I didn't try. Let me try reloading AvP and see if it works. I was just launching it as normal

[upper abyss]

I agree .. only ran into one game that didn’t boot ..

Some football game ..

[mental briar]

arena football?

[upper abyss]

I think so

I got hung up killing nasiz and their dogs in wolfenstein to care

[mental briar]

evil fucking dogs

let me try arena football

[upper abyss]

Also I played more white men can’t jump ! The game more than anyone has since the game released lol

And not a single character from the movie is included in the game .. WTF!

[verbal coyote]

I have been trying some homebrew games with mixed results, but I don't know if this roms works on real hardware anyway

[mental briar]

arena works ok on both builds on my mister pi. going downstairs in a bit to see what's happening on the misters down there

[upper abyss]

Yeah a couple of homebrew games crashed my MiSTer so I stopped trying to load em

[upper abyss]

Hang on I’ll double check quick

It’s called brutal sports football.. still no load ..

Core just growls at me

[mental briar]

oh brutal sports. lemme look

that was working on dual a couple of builds ago

[upper abyss]

I’m on single running the latest unstable core

[tranquil cape]

brutal sports works here - single build, latest

[mental briar]

something to try real quick, taco. try to load brutal sports and, when it fails, go into the core menu and reload the core

thats the only way I can get cybermorph to load

[upper abyss]

Cybermorph worked fine for me .. but yeah trying a quick reset

[mental briar]

yeah, something weird about cybermorph for me 🤷
