aa15fb558ed656209ba42235bb36967f boot0.rom.old
Same behaviour with those 2 BIOS

warm oasis
#

The WIP DB has been updated with the newly named 3 BIOS files, if people using that want to check that things are working as expected

tropic rock
#

Memtrack should be off and remain off. Enabling it currently can break things.

sterile moss
#

Enabling that is the only way I can get the red jaguar bios screen to load (at core launch and when loading a ROM)

#

without that enabled (after deleting the jaguar files in /config) its just a black screen, unless 'CD Enabled' is enabled, then I get the CD BIOS

#

was just going through all the settings to see if any made a difference
Doesnt matter if boot2.rom is present or not, enabling the setting lets the red BIOS screen show

warm oasis
#

Hmm, so using these 3 new BIOS files and the new dual ram (one versions back, not the count 0 one) I get a black screen on core launch and loading cart game also gives black screen

sterile moss
#

same for myself and Jesusfish

warm oasis
#

memory track is set to No

sterile moss
#

try enabling that and save settings, reboot core

warm oasis
#

Setting it to Yes and reset gives me the red jag bios logo

tropic rock
#

You have cd off?

sterile moss
#

if you enable CD enabled, CD inserted and set CD tracks to 2, then CD games load normally and you now get CD bios at core launch

#

correct

warm oasis
#

CD enabled is defaulted to No

sterile moss
#

reset settings, deleted all jaguar files in /config

#

behaviour above still the same with CD enabled off and Quick CD off

warm oasis
#

So is the issue that the default settings need updated?

sterile moss
#

i have the same behaviour as you moondandy, with both the K and M BIOS revisions as boot.rom or boot0.rom

warm oasis
#

Loading a cart game just boots the red BIOS again

sterile moss
#

yep, unless you disable 'memory track', then its always black screen unless 'CD enabled' is on

warm oasis
#

So is there no combination of settings that enables loading carts and CD games, currently?

sterile moss
#

CD games work well, I've not found a combination that lets the normal BIOS load fully / ROMS to load

tropic rock
#

Not sure why you are having problems. It works for me with both builds. I just reset my settings and did a cold boot.

sterile moss
#

ill play around with it some more, last did an update all a few days ago

#

misteraddons stack from 2022

tropic rock
#

What cd bios did you use?

sterile moss
#

6e844759720226e58d55ecaf33608a13 boot0.rom
aa15fb558ed656209ba42235bb36967f boot0.rom.old (sorry that's one of my modded ones, BCFE348C565D9DEDB173822EE6850DEA is the same)

tropic rock
#

boot1

sterile moss
#

my bad
77cd95c7ad06a39f4c59995094aa10f9 boot1.rom

#

CD games load OK with that under both of today's builds and Jaguar_ReworkDual_20250730.rbf

tropic rock
#

Yeah. Those are the two I am using. (I tried deleting boot2, didn't matter for me)

sterile moss
#

i tried having boot0.rom / boot.rom / both of them just in case, all the same here

warm oasis
sterile moss
#

most odd

warm oasis
#

That's the 3 added to WIP DB

tropic rock
#

What SDRAM? 2 128s?

sterile moss
#

yeah 2 128MB sticks from misteraddons

warm oasis
#

Yeah, dual 128 for me as well

tropic rock
#

Can try putting the BIOS back in BRAM...

#

What game are you loading? Tempest 2K works for me

sterile moss
#

AVP, air cars, atari karts, tried a fair few others

warm oasis
#

Just tried that and get the red BIOS again, I was trying AVP before

sterile moss
#

the red bios screen is still meant to launch when the core is loaded yeah?
Unless CD Enabled is on, then you get CD BIOS/CD player

tropic rock
#

yes

sterile moss
#

really odd that enabling 'memory track' brings that back

tropic rock
#

I get a red screen if I turn on memory track. It loads correctly if I leave it off.

sterile moss
#

black screen on core launch and after loading ROM here with memory track disabled

warm oasis
#

Yeah same here

tropic rock
#

Um...Whoops. I just realized I am not running 2 128s. I am using 1 32 and 1 128.

sterile moss
#

Im ignorant of how that'd impact it but it sounds like it would šŸ™‚

#

tested jesusfish's single SDRAM build just in case, its the same

tropic rock
#

I thought I coded this to handle both anyway. Must have messed it up.

sterile moss
#

fixed šŸ™‚

#

works with stock/modded K BIOS also

tropic rock
#

Ok. I need to spend more time to figure out why it doesn't work in SDRAM on 128. But not right now.

sterile moss
#

Thanks for looking into it, appreciated

warm oasis
#

Nice one, thanks!

#

Have deleted the previous cores from WIP and added this new dual ram one

mental briar
#

Iā€™ll build a single ram core when Iā€™m up and caffeinated

mental briar
#

i updated the sys and am building a single and dual ram core

#

once I confirm they work I will push them back to main and update the WIP database

#

I will never not think the jaguar bootup sequence is some homebrew thing

mental briar
warm oasis
#

Ah, cool. Maybe worth doing a PR so GR can merge in the update for future builds

mental briar
#

yep, thatā€™s my plan

humble bluff
warm oasis
#

That could be useful if Co-Jag arcade support is ever added, that has at least one lightgun game

#

Oh, lightgun support was actually added in branch? I misread and assumed that was a feature request issue. Any reason not to merge that in?

humble bluff
#

I added it shortly after cheats. It's probably not a priority since there is only two pieces of software that supports it and they are just demos.

warm oasis
#

Ah, nice. Maybe we can get a test build run off

uncut atlas
#

if it works, ill merge it

humble bluff
#

"Works for me" šŸ™‚

uncut atlas
mental briar
#

shit, I think the single core version has the 9.2 audio issue

#

dual sounds fine

warm oasis
#

Are people OK with the other menu changes in the lightgun PR?

mental briar
#

@tropic rock apologies, I pushed everything back into the main branch rather than you cdlatest branch. let me know if you want me to do the PR over

tropic rock
#

No worries. I did not mean to create that branch there. I just wanted it checked in somewhere so I didn't lose it (failed hard drives last year made me more cautious). I will likely delete it and do it correctly at some point later.

tropic rock
#

It doesn't really matter though.

ashen spoke
#

Whatā€™s the build I should pin?

#

Ok I found both the single and dual

#

I know how you feel but any progress is exciting, even if itā€™s lateral. Weā€™re all here to help test but also to cheer you on dude. Youā€™ve made countless people happy with your core work and turned a lot of people into new fans of the Jaguar, myself included.

Keep on kicking ass, we all appreciate what youā€™re doing no matter how minor you feel it is.

#

I just started dinner but will give it a test in a bit. Thanks for the work.

dim sundial
tropic rock
#

Great. Looks like I found it.

mental briar
#

let me know if it's in a place where I should build a single core build

vernal arrow
#

Am super excited to see all the progress and collaboration!!! Keep up the amazing work.

Never thought Id see the day I actually enjoy the Jag and CDI but here we are, lol

Looking forward to the 3DO core at some point too

Jaguar_Rework_dualram_sdrambios_20251118.rbf is loading reliably with M bios
K BIOS seems to need a reset after loading a ROM sometimes or it stays on red jaguar screen

midnight robin
#

@tropic rock Is it a good time to ask for the "Vertical crop" option that all other console cores have?
It allows to have big screen area + good scanlines.

tropic rock
#

I am working on other things right now (I got the freed up BRAM to add a third cache for single RAM last night=3/8 of the the total DRAM space). Feel free to make an issue (or a PR) so it gets done eventually.

gentle bobcat
#

Finally got a chance to test out the new build this morning as my older son was hogging the TV playing a Wii U game after dinner last night. No loss of functionality noted.

ashen spoke
#

What Wii U game

gentle bobcat
#

Legend of Zelda... whichever one they have for the Wii U.

#

He has a lot of them.

dim sundial
#

There were 2 on the Wii U, Wind Waker and Twilight Princess

warm oasis
#

And Breath of The Wild

#

There was a Hyrule Warriors as well

and the virtual console games

And the CDi games

Ah yea, I forget botw was on wii u too

Do the latest rework cores posted do Jaguar CD too?

hi all. what do i nae the bios file to and do i put it in /games/jaguar?

#

is it boot.rom?

dim sundial
quasi hill
#

ah ok so it not cd_bios for cd

#

ty much

#

hmm I get a red juagur screen on bootup

#

do you have the crc32 for the bios by any chance?

dim sundial
#

You will need the most recent core posted yesterday in this channel to autoload the cd bios.
A red jaguar screen on boot is normal I believe, it means you have no cart inserted. Try loading a game.

quasi hill
#

FB731AAA

#

tat looks correct for the crc32?

#

I see. I did grab the latest singlerework, ty

mental briar
#

boot1.rom for the cd bios

#

And you need to enable 2 cd sessions, enable cd, and cd loaded

quasi hill
#

ty. I'll try again

#

working, thanks all!

#

If the files in the WIP DB are all the final ones for the core to run they could magically find there way into the BIOS DB

Updated the Jaguar CD Setup pin - #1055574003810578503 message

I got lazy and edited my MGLs for the Jaguar CD games to use <setname same_dir="1"> so I have the CD options set automatically.

#

I have the correct CRC32 for the Jaguar CD bios, named correctly in the right place, and the latest core, but when I try to load the .cdi extension CD games, with the 2 CD sessions, CD enabled, CD Inserted, I get the CD with a question mark on it upon loading attempt. What ight I be doing wrong here?

mental briar
#

I had that issue too for a while. Is this on a fresh boot of the core?

pseudo salmon
#

Just turned on the MiSTer and launched it, yeah. Iā€™ve never run this particular core either; just grabbed it. I had the previous build before though.

mental briar
#

This core, yeah? #1055574003810578503 message

#

also, single or dual ram?

#

I will try to boot it right now and see what I have to do

#

anything to avoid doing real work

pseudo salmon
#

November 18th's release above, yeah.

#

The one from single ram.

mental briar
#

ok, lemme poke at it quick

pseudo salmon
#

Thank you.

mental briar
#

something to keep in mind: there are a couple of single ram builds from the 18th. so unless you're sure it's the one in that message, I would grab it again in case

#

with that said, let me see if cds boot

pseudo salmon
#

Let me try to verify.

mental briar
#

ok, here is what I did:

  • booted core
  • Changed CD sessions to 2
  • changed CD enabled to YES
  • changed CD inserted to YES
  • selected a .cdi image

I did not select the bios (as long as it's named boot1.rom, you're fine)

This booted baldies without issue

pseudo salmon
#

Yeah, itā€™s that one for certain.

#

Trying your steps now.

#

Youā€™re choosing ā€œLoad CD *.CDI, and not ā€œLoad Bin *.BIN,CDI right?

#

It loaded Baldies just fine. I didnā€™t try this game previously. Is there a compatibility list? I tried three others.

mental briar
#

all games should work

pseudo salmon
#

Well, itā€™s working this time around, which is nice. Thank you.

mental briar
pseudo salmon
#

Odd. Baldies loads each time, but I canā€™t load VidGrid.

#

Maybe itā€™s a bad dump, Iā€™m not sure.

#

Vid Grid does one of three things:
1 - Loads the spinning wheels loading screen, then goes black
2 - Loads the square behind the logo that grows, then shows the CD controls screen
3 - Just loads a black screen

mental briar
#

there was something funky about vid grid

#

I think there was a specific dump that was needed

pseudo salmon
#

So far, all games load except Iron Soldier 2 which behaves like Vid Grid

#

Ah, makes sense.

#

Vid Grid is my favorite haha. Iā€™ll have to figure it out.

mental briar
#

#1055574003810578503 message

pseudo salmon
#

Okay, final results: Primal Rage loads the ? CD, Vid Grid does the three different fail types, and Iron Soldier 2 fails. The rest seem to load most times, with occasional games I have to load 2-3x and it works. I love the core so far, as I enjoy this weird piece of gaming history, so thanks for making it.

mental briar
#

it may be that the single ram core can't play those games yet as well. it's not 1:1 with dual ram

#

grey is working on that

gentle bobcat
#

If I remember, I'll test both of those CD games tonight on a single-ram system.

mental briar
#

vid grid loads on dual ram (but it crashed while playing the game)

#

Iron Soldier 2 boots

#

I cannot get primal rage to boot, which seems like a regression

#

Maybe another dual ram person can confirm that

#

oh wait, on reset it booted

#

ok, all three boot. it's fussy but they all are playable

#

definitely feels a little more unstable than normal, though. seeing crashes in cd games

pseudo salmon
#

Odd, I actually managed to get Primal Rage to boot on single RAM.

mental briar
#

oh I was on dual ram. it was finicky

#

all the cd games were

#

maybe related to things being moved around

frigid dock
#

My god how hilarious would it be if you followed this up hours later saying "....it's great!"

mental briar
#

i still haven't opened mine

dreamy hinge
#

good idea. keep that collector's item sealed

mental briar
#

My kids need something to retire on. God knows I will have nothing left

dreamy hinge
#

but they'll have all these misters and crts and controllers

mental briar
#

exactly. need to keep them boxed

dreamy hinge
#

surely they won't just give it away to a MiSTerDolch

mental briar
#

gonna get a super station founders edition graded and then return it if it doesn't come back a 10

#

they will extract full value from your collection

#

@pseudo salmon I have a guide on playing Jaguar CD games pinned if you ever need to reference it in the future - #1055574003810578503 message

gentle bobcat
#

Ok, I tested both the Dual RAM and Single RAM cores (1118 built by TheJesusFish) and everything worked for me.

#

So, things others had reported problems with, for whatever reason, worked fine. Including Iron Soldier 2 CD, Vid Grid, and Primal Rage.

#

I think I have the lesser preferred BIOS as when I loaded carts, I often had to reset the core.

mental briar
#

I wonder if itā€™s because Iā€™m loading over the network. Maybe some instability with that in the core

#

I may have time to test loading via sd card later today

#

Iā€™m using the M bios

warm oasis
#

Do we know what the difference between the M and K bios actually is? Is one better than the other in some way? Is it just the two out there?

ashen spoke
#

I didnā€™t even know there were different bioses.

tropic rock
shut night
#

Undoubtedly a silly question, but if I want to use MRA's for all the CD games (Robbie I think you posted yours previously), is it at all possible to have my cdi files live in an "Atari Jaguar CD" folder on my USB ssd? Ie, will the core be able to find them and the bios etc?

mental briar
dim sundial
#

<setname>Atari Jaguar CD</setname> don't use same_dir="1", You'll have to copy bios files to that dir as well.

shut night
dim sundial
#

You would have to set those options up and save settings after launching the MGL core for the first time

shut night
dim sundial
#

yes, the setname setting in the MGL file makes it use completely different configuration files

Super glad we have the core now https://youtu.be/9ZaYlVGxTZ4?si=gPyXyIRM1tzWuWiQ

#

I tried launching Tempest 2000, but I just see a blank screen?

mental briar
#

Sounds like a bios issue. Are you getting the red jaguar screen when you boot the core?

raw stream
#

Do I need a Jaguar bios? All I have is the tempest .jag file. I don't see anything when booting

dim sundial
#

wait, does update_all get the bios files for the jaguar yet?

warm oasis
#

It doesn't, but if the files in WIP DB are fine then they could find their way into the BIOS DB

gentle bobcat
#

Wasn't there a bios in the pinned items?

#

Yes there is... the MiSTer-kun one.

#

Not the CD BIOS though.

ashen spoke
#

yeah, I dunno about the copyright on that. What will likely happen is we'll talk about it, @uncut atlas will come in and correct us that it's all been open sourced. Someone else will point to a news article reinforcing that and I'll add it to the pins. And then in about five months someone else will ask about some sort of bios, which will initiate the same song and dance for the fourth time.

Are .jag roms compatible? I dunno if I have tried those

Oh good catch

#

I have a qmtech mister. I'll try the single ram tomorrow

warm oasis
#

Is anyone able/willing to stake that the three BIOS files in the WIP DB are all working with the core as expected and it would be good if they magically moved to the BIOS DB so we're distributed to everyone via update all?

mental briar
#

I can tell you that they work for me. But I will delete them and test again in a bit

#

just to be sure

mental briar
#

I deleted and installed direct from the WIP database

warm oasis
#

Ah, what does 2 do again?

mental briar
#

memtrack (saving cd games)

#

it's the right file

#

but it hasn't been added to the core

tropic rock
#

I am currently trying to figure out why the memory track cart seems to be failing the copyright check in CD mode. You should be able to hold option and have it boot the save manager menu. You can load it like a normal cart and it does boot correctly to the menu. Or just turn on memory track without cd on and it should treat it like loading it from the OSD and go to the manager.

mental briar
#

So I have noticed that, since the last update, CD seems real unstable for me. Games will boot, but they will crash after a while. I cannot finish a match of Primal Rage, for example. I'm wondering if other folks are seeing this because, if so, it may be a matter of the images being stored on a nas

nova portal
mental briar
#

ok, so maybe not just a "me" problem. @gentle bobcat sorry for the ping, but can you also look at this when you get a chance? Absolutely no rush. Just looking for another point of confirmation šŸ™‚

gentle bobcat
#

How long would I need to play any given game? On VidGrid, I cleared all but to of the videos on the first level. In Primal Rage, I just did one match.

mental briar
#

that's more than long enough. and that's using the latest build from [here](#1055574003810578503 message)? (dates aren't going to to be a good judge because there are two single ram cores with the same date)

gentle bobcat
#

I'm out of town and I don't have all my stuff with me but I can do some testing.

mental briar
#

you're single ram, yeah?

gentle bobcat
#

That's all I have with me at the moment. A MiSTer Multisystem 2.... and a MMS1 as well.

#

I have two dual RAM MiSTer Pis back at home.

mental briar
#

let me try single ram

gentle bobcat
#

I didn't bring my Jaguar controller. šŸ™

#

I'm primarily focusing on testing out the MMS2 with the 4-port N64 SNAC cart so I brought 4 N64 controllers... and ran out of room.

mental briar
#

love it

#

no crashes on my mister pi single ram stack so far...

midnight robin
#

What I have noticed is that, at least with latest version of the core on dualRAM, loading a cart game and the loading a different one, the video stays black forever until chosing the RESET option on the core.
In other words, the auto-reset that the core does when loading a new cart causes black screen.

mental briar
#

Single Ram still going strong

#

played matches, let it go back to the attract loop

#

dual ram crashed after about 3 minutes of attract loop...

#

I'll try it on a different dual ram setup too

mental briar
#

Ok, I think the dual ram issue is my fault. I think the build I built has issues - might be a timing thing. The sdrambios core is in better shape. Gimme a second to fix things

#

I can't edit Robby's pin, so @ashen spoke, when you see this, can you update the pin

#

I'll get this in the WIP repo

warm oasis
#

I've chucked those in WIP now

mental briar
#

thanks buddy, got pulled into a meeting

#

it was just dual that was different. it's the core grey posted that I just renamed

#

Also, if you guys haven't played with Zakk's controller stuff, it's super cool. I played AVP on an M30 last night and it was glorious

#

I also played it on an NES controller....it was less glorious, but it worked

warm oasis
#

Do these cores have the lightgun PR in them?

mental briar
#

no

#

that's been sitting for a while

#

I got the impression that grey would look at it after the cd stuff was buttoned up (and the core was "done"). but I don't want to put words in his mouth

#

playing AVP for an hour last night reminded me how thankful I am for this core. terrible system, wonderful core

warm oasis
#

I think the guy who did it was quite keen for some testing, maybe worth a test build for it

#

The 3 BIOS files are now in the BIOD DB btw and removed from WIP DB

#

So anyone who needs them just needs to run update all with BIOS DB enabled

humble bluff
#

I have test builds in the PR.

midnight robin
#

@mental briar With these, using the DualRAM build, I still see that loading a second game without resetting hangs the console, causes black screens, etc

mental briar
#

vidgrid doesn't like it when you open the menu, though

midnight robin
mental briar
#

oh ok, lemme look

mental briar
ashen spoke

mental briar
#

Sorry, my build was bad. These builds don't yet meet timing, and mine was probably further off than grey's (I updated the sys, that's why I built a different one)

gentle bobcat
#

So, what is the preferred most recent build?

mental briar
#

The ones I posted today. Itā€™s the same single core build

gentle bobcat
#

Ok, thanks.

hidden blade
#

The latest WIP single core causes a lot of trouble. still a build issue?

mental briar
#

The one I posted today should be fine. I was futzing with it

#

Primal rage ran on a loop for hours

hidden blade
#

Tried games like Flashback and others (Pinball Fantasies, Bubsy) and mostly got a black screen, screen flashing or when it worked without sound.

mental briar
#

Iā€™ll take a look in a little bit. I didnā€™t test roms, so itā€™s possible those arenā€™t working. Do we know if they were working before?

hidden blade
#

Most roms work fine with an older test version. Iirc one from July with cheat support was the last one i tried some month before.

mental briar
#

All three of those are working here (insomuch as I loaded them, got into a gamed and then moved on)

5.jpg 6.jpg 7.jpg
hidden blade
#

Strange. But it is what it is. Tried the one from yesterday.

#

For me the games are locked up, the core is frozen completely. Only a reset helps.

#

Tried the older core from July, and all games are fine. Maybe it try to delete the configs.

mental briar
#

swap your bios for the one in the bios DB if you haven't already

#

the old bios was...K? The new one is M. the core is built for M

hidden blade
#

Do you have it? I don't know which one, from no-intro?

mental briar
#

if you delete your bios and then enable the bios database in update all, it will grab it

hidden blade
#

The update_all.script doesn't redownload the Jaguar BIOS files for me. Will try it later.

#

Guys. It didn'T work. I'm not THAT stupid.

#

That all was discussed with TheJesusFish above. I will try it later. The script got tons of updates lately. Maybe i delete it and try again later.

mental briar
#

I think jack is right. it didn't pull it down for me either. let me try unmounting and remounting cifs

#

yeah, it's not pulling them.

hidden blade
#

Thank god. I thought i'm getting old. Ran the script 20x times. No errors, no Bios downloads.

mental briar
#

i think we need to do a full check. I just have to remember how to do that

hidden blade
#

Ah, now it's grabbing something.

#

Now the games are working. Another x-file solved. Don't know why it took so many atempts, but the correct Bios is downloaded now.

warm oasis
#

It may be that you need to run update all to update its self and then run again to get the files, there was a bug that @wraith kiln fixed yesterday that meant the files weren't being grabbed. If in doubt run update all twice and see if that fixes it.

hidden blade

Update_all doesn't like to check again once it does that

Downloader was updated recently and changed the way it handles file checking. You might need to add this to your downloader.ini if it's not pulling certain files:

[MiSTer] file_checking = 'exhaustive'

mental briar
#

what's weird is that it worked fine in the arcade folder when I deleted a few MRAs this morning to test something

#

so it's something with the bios db (and maybe others)

warm oasis
#

I think @wraith kiln will need to have a look under the hood again when he has a few

wraith kiln
#

The ā€œbalancedā€ option trigger an exhaustive check when it detects more tham 2mb that have been deleted

#

Which is lower than the size of any core

#

Mras are usually smaller tham 2mb, so deleting just a few of them wonā€™t trigger an ā€œexhaustiveā€ update

#

If you are the kind of guy that deletes few mras often, just opt into file checking exhaustive

mental briar
#

well what was weird was that I deleted 3 MRAs, and it pulled them back down without issue. I deleted the 3 bios files, and I had to trigger an exhaustive check for those to come back down

(speaking of MRAs, I pinged you on a weird MRA github issue that relates to the 3 I deleted)

Finally. Still need to hook it up to save and load to sd card to make it persistent across power off and probably need to move it to different memory (DDRAM?) so it can be transferred without disabling the core.

boot2 is actually the save file?

so is boot3 the cd bios then?

mental briar

Jaguar Bioses (and what they mean to you)

  • boot.rom - The Cartridge bios (you need this play carts)
  • boot1.rom - The CD bios (you need to play CDs)
  • boot2.rom - This is the CD save cart (Memtrack - you need this to save your CD games)
warm oasis
#

I added the extra line to my download.ini and still not grabbing the files, something definitely is up

slender valley
#

Huh, why not just have a .sav file per game? Most cores do it that way

ashen spoke
#

I think it needs to read the hardware to save.

#

No internal memory at all, needs a cart.

#

But to your point that could still be saved on a per game basis, I assume

tropic rock
#

boot2 is the ROM on the Memory Track cart that contains common code for games to use when accessing the save eeprom on the cart. There are actually 3 different models: 2 different eeproms and the romulator which uses RAM instead of eeprom but is only a development device. The code for using all 3 is in the ROM and it autodetects which is being used. I implemented the romulator as it is easiest. The actual save data is in the ram or eeprom and will be a separate file when it is hooked it up to the sd card.

Should also be in the readme if anyone is so inclined to add it. Not me!

Let us know if it grabs the BIOS files for you OK, there seems to be issues

#

Since these are public domain, here are the three BIOS files that update all (should) grab if you use the BIOS DB (but is being temperamental currently).

šŸ“Ž Jaguar_BIOS_Files.zip
slender valley
#

So I guess I can delete my CD bios I have been using since boot1.rom is going ot take it's place?

#

Their bios files are public domain? Neat, so then does update download these or still only update_all?

warm oasis
#

Only update all right now

slender valley
#

(Though I can't imagine anyone here not using update_all)

wraith kiln
#

These 3 roms are quite small, so deleting them won't trigger to redownload them with the current 'balanced' file checking logic

#

I think I'll have to add something for the files that have overwrite: false, like the bios ones, since the program asks you to remove them if you want to download the new version.

#

And that's not happening if the bios files are too small.

#

So for now, I'll lower the free space diff check, to just 512kb instead of 2mb

#

But later I'll add specific logic to check the overwrite: false files when the file checking is set to balanced.

#

That being said, I don't think that caused the problem to that user

#

Just to @warm oasis

#

I'm unsure he reported that correctly, would have to verify that with a log to be sure.

slender valley
#

Would they re-download I I temporarely set it to re-verify all files?

wraith kiln
#

In general, the tip when someone suspects exfat corruption should be now to try file_checking = verify_integrity in downloader.ini as it's described in the readme, that will check that all installed files have the correct signature

You have to remember that 3D gaming was new at that time and the PSX didn't come out for another year... nor was the N64 out either.

#

PCs were the only place for 3D at the time... until they came out with StarFox on the SNES... which basically had a graphics GPU in the cartridge.

#

(and the Saturn wasn't out yet either)

#

But Checkered Flag is a horribly flawed game and it should be considered a form of torture.

sudden pelican
#

dunno. when the jaguar was available in stores here I had already played NFS for over a year I think.

#

consoles were too expensive anyway

#

there was always a gap of a few years between 'release' and 'widely available in stores' in Europe

#

except for warez of course

#

around 2002 or so a store in my neighbourhood had a whole stack of new-in-box jaguars for cheap (50 euro or so), and I was kind of tempted to buy one. did not do it after all,

Atari wanted Virtua Racing with Checkered Flag... but their development tools and development teams just weren't enough resources... and Atari was broke... so they just released it before it was fully baked... because that is the best they could do at the time.

Oh wait, I think @nova portal is correct. Looks like tdelage built new cores with the mouse/keyboard stuff

#

I didn't realize that got merged

#

hmm, hold on @nova portal does your version have the ability to load cds? I'm wondering if they built the core based on the main branch, rather than the CD branch

#

Either way, there is new stuff in the CD branch since nov 18th, but I usually wait for Grey to šŸ‘ a new build

#

I got mouse speed stuff confused with lightgun stuff

#

I asked Tdelage what branch they used to build those cores

nova portal
mental briar
#

ahh, then yeah, I would use it for the time being. Grey has been moving stuff around (something about bram and sdram and ram ram ram ram ram ram) to make more room on the single core, so it could be that it's an older build before that, or if his latest changes smoothed that stuff out. Won't know until tdelage tells us which branch they used

warm oasis
#

I think GR needs to get his reworks finished off so Kit and people can get their merges and fixes in and hopefully it will be about ready for prime time

mental briar

confirmed it's the latest build. If grey is already with it being posted here, we can

gentle bobcat
#

Have any of the OSD options collapsed / been combined yet? For example, the load bios and cd bios options can go away since they (I believe) are auto loading now. It would be nice if the load bin images items were removed as they are likely not needed anymore... and lastly, it would be amazing if all of the options related to CD settings just became "Load Game .cdi file" and "Load Audio .cdi file".

humble bluff
#

There are alternative bios that you may want to load. OSD cleanup is planned.

warm oasis
#

How are we looking more widely with homebrew on the core now, does anyone know? Seems there are issues with mutant penguins in latest build, but are other things running OK?

slender valley
#

We don't need to manually load the CD bios anymore? What about setting cd sessions or cd to enabled and all of that? Or can we just load a disk image now?

dusk slate
slender valley
#

Thanks

It's like two options you need to set. I just forget exactly what they're called off the top of my head. CD inserted, and enabling the CD mode. Something along those lines without booting up my MiSTer to check.

slender valley
#

IIRC soemthing about setting session to 2

nova portal
#

I've noticed that with the new boot.rom bios we use now with latest versions of the core, the option in the OSD to patch cart index that allows Soccer Kid to boot is not working anymore. If i replace the current boot.rom with the previous version of the BIOS, then the option works again but loading carts with this old BIOS becomes very sketchy as it requires frequent reset (tested on single RAM core but i guess it's the same with DUAL) šŸ¤”

But seriously, Video Game Esoterica would really like the arcade mode implemented (the CoJag) as there was an arcade machine made from the Jaguar but that thing had either a 68020 CPU (rather than the 68000) or a MIPS R3000. I don't think either of those CPUs are publicly available as free FPGA implementations. I think there were two games?

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

Atari CoJag

The Atari CoJag is an arcade board released in 1995 by Atari Games (a then-subsidiary of Time Warner Interactive that licensed the console hardware) before Atari Corporation's reverse merger with JT Storage. It was based on the Atari Jaguar chipset.

# gentle bobcat But seriously, Video Game Esoterica would really like the arcade mode implemente...

So yeah we have a 68020, and according to wiki maybe we have a MIPS R3000 in the PS1? This is a bit confusing:

Sony for their PlayStation and PlayStation 2 (SCPH-10000 to SCPH-700XX - clocked at 36.864 MHz for use as an I/O CPU and at 33.8688 MHz for compatibility with PlayStation games) video game consoles, and NEWS workstations, as well as the Bemani System 573 Analog arcade unit, which runs on the R3000A

fallow salmon
#

yeah psx is a mips chip

#

it had two different jobs later on, when sony used it in the PS2, thats what you're reading about there

warm oasis
#

Ah OK, nice. So when it says Co-Jag used MIPS or 60820, does it mean that some games were only on boards with MIPS and others with 60820, so you would only need to support one of them in the core, or you would need both to support the entire library?

#

Also wondering if there are any other chips on the board not on the Jag

Did you ever get pics of the board you got? Which one was it again?

thorny swift

#

Area 51 is 68020. Rest are MIPS

warm oasis
#

Ah, got you, so would need to support both

thorny swift
#

and I believe an extra DSP for low level IO shit

warm oasis
#

One issue is if Robert fully implemented all the features in the MIPS for the PS1 core or just the ones he needed to run the PS1

thorny swift
#

if he was smart only what he needed would be my guess

#

but yeah CoJag is just 68020 vs 68000 and the pivot to MIPS. Plus a little bit of extra silicon to handle IO and HDD not cart as you aren't directly addressing the games via a cart slot but a HDD

warm oasis
#

Yeah I expect that is probably the case, maybe @warped basalt can tell us a little about his PS1 MIPS 3000 implementation

#

I expect it is likely that more CPU features would likely need to be added to use it elsewhere

thorny swift
#

I can take a deeper dive into the board next month when we are at the new house

warm oasis
#

That would be interesting

#

More documentation there is, then more chance someone might want to try implement it

thorny swift
#

but I have all the documentation in the world on the 3DO M2 and nobody is banging down my door for THAT šŸ¤£

warm oasis
#

We have virtual lightgun support now, so assuming that can work on the co Jag games then that is one part done and ready

thorny swift
#

I am always surprised nobody has ever tried all the PSX arcade games

#

Especially the bone stock arcade boards that have exclusives

warm oasis
#

I expect that will be one thing we see on the next board, when there is room to breath for the PSX core. As it is, it doesn't sound like it would be easy to add anything to it or split it off and remove parts to make room for extra functionality.

Final note about the core and extensions. Currently all cart files are handled the same way and loaded into 0x800000 and assume the jump address is in the standard location for carts at 0x800404 regardless of extension.

Another thing it definitely needs is a simplification of the menu as it has a zillion options... and given all of the stuff he has working now, perhaps more than half of what's there could either be completely eliminated, or collapsed down. For example, you should not need so many options for CD stuff. Just have "Load game CD" which would just automatically set all of the settings one has to manually set now... and "Load audio CD", ditto... and "Load Game cart". Of course that is me talking... errr writing... and I know absolutely nothing about FPGA software development. But I can provide encouragement and thanks in abundance... and rewards if @GreyRogue accepted rewards of any kind.

slender valley
#

I assume the current CD options are just temporary since the core is still in development

#

Most of these options will probably either go away or we put under some kind of advanced or debug menu and you would just simply need to choose load CD like you said for the stable version

#

I assume the stable version would likely not be limited to CHD either and likely have BIN/CUE if not also CHD support

#

Just that clearly that kind of stuff is not a priority over getting the CD support itself ironed out first

gentle bobcat
warm oasis
#

If I remember Zakk said it is possible to do CHD but it would be a sizable bit of work for such a small library and ultimately won't save much space

slender valley
#

Were Jaguar disks multisession though?

#

DC was multisession mostly because the main data was in a proprietary format while still needing a part of the disk to appear as a standard cd

dreamy hinge
#

most jagcds are multi session

ashen spoke
#

The only benefit CHD would bring is consistency with other cores.

slender valley
#

It would save a little space, but yeah, the consistancy is a bigger thing personally. Just would be nice that all cores can have the same image format

#

Well, actually, now that I think abuot it it's still not consistant because you can't use CHD for games with indexes over 1

ashen spoke
#

It would be nice if the CHD devs fix that

#

So many retro game emulators and front ends utilize CHD that itā€™s kind of ridiculous to not solve a bug that breaks game behavior.

slender valley
#

Wasn't CHD originally just made to handle laserdisk games on MAME

#

But yeah, the format is kinda becoming a catch-all so it really should be updated to handle those cases

#

I remember the CUE file of one of my saturn games is a laughable mess, EACH track has like, 30 indexes

tropic rock
# slender valley Were Jaguar disks multisession though?

All JagCD games are 2 sessions. The first session is audio. The second is game data (in audio formatted data). The CD BIOS will not boot the game if it does not have sessions and it checks the second for copy protection with checksums.

slender valley
#

JaguarCD had copy protection?

If a single session cd is inserted it will bring up the audio player.

BTW, MiSTer Add-Ons had a JagCD unit for sale. I think he wanted... will look again... $1200 for it?

#

I'd consider buying it for $250. šŸ™‚ I already have a great box with inside casing... just no actual unit.

low dome
#

I sold mine (atari jaguar collection in pic) about two years ago for $2000 even, so price seems a little reasonable. One thing about the JagCD, it's very fragile. It works 70% of the time I had it. Kept it in a storage and it stopped working for some reason. And yes, you can play burn disc on it.

download.png
#

I'm just worried, if Mister Add-On shipped the JagCD it might not work out the box right away since it's very fragile, keep that in mind..

rain sierra
#

You insinuating that Atari cut corners with quality and durability or somethinā€™!?!?!?

low dome
#

just speaking from experience with the JagCD

rain sierra
#

lol Iā€™m just messinā€™

#

Atari is not synonymous with quality

low dome
#

the Jag console however works everytime, but feels cheap (shell, parts and buttons), lol.

rain sierra
#

Just seeing the Jag edge connector for analog video which is just a section of exposed motherboard is enough for most people to come to the same conclusion.

tropic rock
#

Some of what I read implies a lot of the "fragility" issues are really the reduced error correction. Any failure in the data can cause the encryption check to fail causing it to refuse to boot. It always checks the boot data and the encryption data needs to be error free. It then checks random segments. Any errors will prevent games from booting. Then any areas that randomly skipped the check can still cause crashes. Most CD formats have built-in error correction in data areas. JagCD stores game data in audio format. Audio data is allowed to have errors which would often be imperceptible to the ear. Hence the increased finding of "fragility".

#

Burnt CDs are more likely to be difficult for the laser to pick up and will have more issues.

gentle bobcat
#

Also, 30+ year old optical drives... aren't really known for their robustness..

#

I think I remember watching one or more videos on how to fix a non-functional JagCD... but it requires a lot of teardown of the hardware and adjustment of a potentiomiter(sp?) if I remember correctly and I'm probably not.

slender valley
#

So they used areas that are meant for error correction for their anti-piracy? And it ended up, surprise surprise, causing errors?

tropic rock
#

No. They used it to allow bigger discs. Error correction takes up space. The amount of space for the encryption is only a couple hundred KB. The format they chose allows 746MB on a disc

#

compared to about 650MB with error correction.

#

Note this decision was made during the early years of CDs so the importance of error correction may not have been very clear. Determining how quickly things degrade requires time to get statistical data.

#

I assume it also would have required at least slightly more expensive chips to process the error correction, but I do not know if that figured into their calculations.

slender valley
#

Wait, so Jaguar CDs are not standard CDs? They can't be read on a PC drive?

#

Seems pretty silly to do that in the early era of CDs too, most early CD games barely used half the disk even when they intentionally tried to cram it with music and FMV

tropic rock
#

They are standard CDs but they look like audio only. The data is just in audio tracks.

The developer of that MK game says he currently wants it only to work on real hardware with the Game Drive. It isn't that it can't work as a ROM file... but he said he wants real hardware owners to get first go at the game before emulators. What it is about the game code that stops it from working on MiSTer, I don't know, but it is supposedly by design.

warm oasis
#

This sounds more like an issue with running the ROM than "game drive" support, if Game Drive is just a flash cart then emulators shouldn't need to support anything. This is very odd.

Is Game Drive some sort of aftermarket flash cart?

#

If the game author wrote it specifically to work with the Game Drive then it shouldnā€™t be supported. Buy the Game Drive and enjoy their game that way.

Game Drive should just be a dumb flash cart, so if something isn't working on real hardware running from it then it would good to find out why, as it should in theory just run on the core if the core is accurate to real hardware.

ashen spoke
slender valley
#

So is it an issue of max supported ROM size?

warm oasis
#

Apparently the game is only 6mb

slender valley
#

Were any retail Jaguar games that big?

gentle bobcat
#

I have a Jaguar with a GameDrive... and yes, it is a flash cart. The author of Mortal Kombat has said he wants the first users of the game to be on real hardware... so, without stating how, he supposedly has it checking for the GameDrive. Once he is done with the game and it gets a freely available public release, that restriction will be removed.

#

While I've had access to a few builds via his Patreon, I haven't tried it yet because I haven't bothered to setup my Jaguar system in a while.

#

I did try the most recent build on the MiSTer and after the Jaguar startup, I just get a black screen, so I assume his method, whatever it might be, is keeping it from running.

warm oasis
#

Ah, so basically he added some sort of DRM in there

gentle bobcat
#

That's my understanding.

warm oasis
#

So the solution is to wait, or for someone to try hack the ROM to remove it

#

That feels extra cheeky seeing as this isn't something he created, but is a port of Mortal Kombat, someone else's IP

gentle bobcat
#

As I mentioned, that restriction is only temporary and will be removed once he is done with development and releases the game. Basically his Patreon subscribers have been funding the development, but once it is done, it will be freely released... and yeah, that probably also has to do with the fact that it is a "fan" game of a non-licensed property.

#

I think thatā€™s super cool, personally.

#

And weā€™re really lucky to have you here with us playing this core with such an expert eye on things.

gentle bobcat
#

@Robby - Because I bought one new when they were for sale... in 1994(?). Took me a while to get one because they were hard to come by. I was a big Atari fan prior to that and I saw the Jaguar as Atari's "last stand". I bought about 18 carts and rented the rest of them at least once. T2K is my favorite game of all time and I generally play it a few times a year... prior to the MiSTer WiP core... and I was very glad to see that come along. When I first got a MiSTer at the tail end of 2019, I was really hoping that someday there would be a Jaguar core. šŸ™‚ I listened to the Jaguar Game by Game podcast episode on T2K and there are a handful of community contributions in the last section of that very long episode... and quite a few people mention that T2K is their favorite game of all time.

#

My first computer was a Timex Sinclair 1000 which I had for about a year before switching to an Atari 600XL. Then in 1985 when the ST came out, I pre-ordered that... and used that for close to 10 years... mainly on Bulletin board Sysems (BBS) and then GEnie and CompuServe... as there were big Atari communities on those pay services. Of course that was all BI... Before Internet. I remember reading the Atari Jaguar FAQ as it was being constructed before it came out... and the hardware seemed amazing. Of course, real life doesn't always pan out like the press releases say it will. šŸ™‚

#

But the Jaguar is just my favorite console... as I really haven't put anywhere near as much energy into any other system since. Of course my sons are way more into gaming than I am, and I'm the "retro gamer" in the household. šŸ™‚

Damn... I started on the NES, Nintendo isn't doing too bad these days... XD

The guy who does those, although he hasn't come out with an episode in over 2 years... is currently working on an episode covering the JagCD... and I'm guessing he may have some MiSTer coverage in there but not certain. I definitely have told him about the MiSTer WiP core.

I've been reading a little bit on that reel-to-reel tape of UNIX from the early 70s that was found at the University of Utah and recently turned over to the Silicon Valley's Computer History Museum. I happen to have a reel-to-reel tape from ~1988 with UNIX Sys V on it that someone gave me. Maybe someday we'll have a PDP-11 core where we can run the original UNIX. UNIX was originally named Unics (like Multics) but no one remembers when the name was changed nor why. That detail is lost to history.

uneven cobalt
gentle bobcat
#

The first couple of years, UNIX was written in assembly as C wasn't quite ready yet to take over the whole thing. I believe that transition from assembly to C was completed sometime in 1973. I never used the original UNIX. Just MiNT on the Atari ST. MiNT was an acronym for MiNT is Not TOS, and later, MiNT is Now TOS... after Atari hired a guy to work on it and it got integrated into TOS to become MultiTOS. Sorry to be off-topic but its Atari related.

#

I checked that a little before Xmas and he hadn't started it yet... even though he had told me via email he definitely was going to do it... just was having trouble finding the recording time. Glad to see he has made some progress.

#

Jaguar is still doing well enough for new games to periodically be created, the GameDrive flash cart has had a few production runs, blah, blah, blah. I'm not saying the games that have come out since its demise have been comparitively good, but beggars can't be choosers. And of course, they have been porting quite a few Atari ST games to the Jaguar as well. I have no idea how much development work is involved in that porting or if it is fairly automated?!?

#

Unfortunately the bulk of new stuff has been cartridge only but there are a few companies that sell digitial roms as well. Just not all of them.

#

I have been associated with quite a number of "lost causes" over the years and the one currently on my mind is the 9-hour documentary series made by Oscar winner Ezra Edelman entitled, "The Book of Prince." Netflix paid the Prince Estate ~$10 million for access to "the vault" and Ezra and his team worked on the film for close to 5 years... and then the Estate refused it because they wanted editorial changes made that the film maker wasn't willing to do (cut 3 hours from it). Now the Estate is supposedly having someone work on a sanitized happy, happy version. I'm hoping someone will leak "The Book of Prince" someday or that the Prince Estate will run out of stuff to sell and will reach back for that documentary in a desparate cash grab. šŸ™‚

There is also a single-RAM version of the core although I don't think much side-by-side comparison has been done and it is generally perceived as the lesser of the two... but not a lot of folks have dual-RAM so the single-RAM core probably is more widely used.

There is nothing special about commercial Jagur carts. They use standard ROM modules so any type of dumper that can attach to the pins can dump them.

Nothing prevents homebrew makers from developing carts with dumping protections at additional cost though.

# slender valley What about reading/writing saves?

All jag cart pcbs I've seen have a space for an eeprom. If the game uses saves it's populated, if not it's not populated. There's nothing special about the carts.

The single-ram core has been usable... but I believe there are a few titles (nothing that popular) that don't work. I believe the list is documented in the testing spreadsheet that is linked in the pinned items.

It would be interesting if someone could have three setups side-by-side... original Jaguar with GameDrive, MiSTer single-ram and MiSTer dual-ram and do an actual comparison. I do have all three but I don't have the space to set them all up at the same time. If one of my kids would move out and I got a spare room... that would be awesome but I'm not holding my breath.

how deep do you want to go?

Your easiest (and cheapest) solution is to just use a keyboard. And, if Iā€™m being honest with you, itā€™s probably the best solution.

If you want to dip your toe in, you can order this monstrosity (although the current price is about 9 dollars more than the MSRP)

If your desire is true madness, you can get a Reflex Adapt from Porkchop (when they are back in stock) and then see if you can find a New Old Stock jag controller on ebay

ancient thistle
#

I'm wanting to go fairly deep. I just got done playing through the full 32X library for the purpose of doing little write-ups and ranking them and the thought of doing the same for the Jag is now in my head. The main hurdles to that would be finding a good controller method and seeing where single RAM compatability is at. Reflex plus a real pad seems like a good option to me but that My Arcade pad looks interesting. Just wonder if it's got good latency.

Cool idea and project! So many people talk about the jaguar an it's games, but hardly anyone finished them especially the whole library. Do you text write ups or have a YouTube channel?

I'll keep looking into both options then, especially if the latency isn't that bad on the newer controller. Seems like it'd be less of a hassle, in any case, and I got a weird thing about using pre-owned controllers. My MiSTer uses an analogue board so I'm limited to just the one stick of RAM, unfortunately, but I imagine there's a compatability list in the pinned messages, just haven't had a second to start going through it all.

I use a Reflex Adapt with an adapter and a Jaguar controller and it works great. Of course you can only use one Jaguar controller. Supposedly if you have multiple Reflex Adapts and adapters you can use multiple Jaguar controllers... but I don't know anyone who has actually give it a try.

#

eBay had a few vendors that had an ample supply of new-old-stock Jaguar controllers but they dried up about a year ago.

I have 3 old stock ones and a reproduction Jaguar Pro controller.

Yep. Works fine. Thatā€™s the only reason i have two on that tv

ancient thistle
#

Looking at OEM controllers and man, the cost of the adapter and controller is maybe pushing me to that other one that was linked haha.

#

Do many jaguar games actually use the number pad, though? I'm not super familiar with the system compared to others of the era.

mental briar
#

A frustrating amount. However, @dreamy hinge is working on something where youā€™ll be able to bind button combos to single buttons. I played a level of avp with an nes controller to test it

#

For instance, avp uses the keypad for weapon selection, strafing and the map

gentle bobcat
#

@ancient thistle - A good number of them do use the numpad. There is a link to scans of them all... and there are some that have been made after-the-fact. There is a company that makes reproductions.

#

@ancient thistle - Check the pinned items. There is a link listed there for a PDF with the overlays.

#

Although I realize you were asking about the number pad specifically, and not the overlays... but the overlays make using the numberpad a lot easier.

ancient thistle
#

Looking at that store now and it's making getting an original pad more tempting. Though that Gamestation one seems to be more within what I can afford, just not finding much info out there about compatibility with the MiSTer.

If you can wait a few days, I can open mine and test it. I feel like @ashen spoke got it working with MiSTer ok, but I think he returned it afterwards

I have the CD BIOS, but I'm not sure what the name is for the save cart, so I'm struggling to figure out what I should be looking for there. I've noticed that several .cdi Jag CD games are also booting as black and white or failing to recognize. Are there specific settings I need to flip to correct that on certain games? Baldies, for example, is one that's launching in black and white. I'm on an NTSC-U CRT and it's not doing the usual image stutter I'd get from PAL games, so I don't think it's a regional issue (though the file doesn't seem to specify what region.)

The best thing you can do is just delete any BIOS files you added manually and when you run update all press up and enable the BIOS DB and it will take care of that for this core and virtually all the others

#

That is the easiest solution

#

Thank you. I wasn't aware they could be grabbed from the update all, so I'll do just that.

Gave that a shot but it looks like some CD games still load to a black screen or to the system's CD player. Thinking it might be whatever cdi files I got unless there's some options I need to toggle beyond setting the CD to 2 and yes on the options below that.

I think you need to properly load the bios too? Or is that step animated now?

@Weatherby - I've seen a lot of people run across some bad .cdi files.

Cool game imo

I believe all the cd games work on both cores. Make sure you have sessions set to 2 and the cd inserted set to yes. You may have to hit reset in the OSD if you get the ā€œ?ā€

Are people using the specific set that has been tested against on the core and not random dumps found from other sets?

gentle bobcat
#

If I understood your question... since the specific information can't be publicly shared (where a specific set might be located), who knows?

tropic rock
#

World Tour Racing is one that some sets have bad dumps of.

#

I got problems with Iron Soldier 2, CD version. It shows the music player instead of the game. Maybe a bad dump?

#

By the way, music is perfectly played.

tropic rock
#

If other CDs are recognized as games with the same settings and it goes to the cd player I am pretty sure it is the image having a problem (maybe a different version of cdi format? I only found limited documentation on the file format). If the format is recognized it would error, not default to vlm.

TruFun Games has released Mortal Kombat Beta v1.1 that only works on real hardware (not sure how he pulls it off but I can confirm it doesn't work on the MiSTer core). He reiterated that once the game is done (and it is very close now I think), he plans to open it up for everyone. This has been discussed here in the channel not too long ago... but there's your update. When it is released, I'll mention it if no one beats me to it.

The core does not implement everything the GD does. If there were a need I might look at adding them, but since the author is planning on releasing it without the specific blocks it probably is not worth the time.

gentle bobcat
#

I concur. šŸ™‚

I emailed Songbird productions about potentially selling just the rom of Towers II enhanced. Mentioning there are plenty of Mister FPGA owners who don't own a Jaguar that would love to play this game. I'm sure they won't be interested but figured worst they can do is tell me to piss off.

ancient thistle
#

Looks like the issue was that the cdi files I had weren't the best rips. I was able to get a better set and everything is booting perfectly now.

#

Which means I get to start looking at repro overlays and jag controllers........ šŸ‘€

slender valley
#

I would still like to see that version running even after the public version is released

tropic rock
#

The GD has extra hardware. That is the part that it is detecting.

slender valley
#

GD?

#

I thought it was supposed to run on a standard jaguar

mental briar
tropic rock
#

GD=GameDrive. It runs on a GD on real hardware. I don't have a copy to verify, but the part that is failing is almost certainly part of the GD that I have not implemented.

Is GameDrive like an Everdrive for the Jaguar?

#

Link was broken, just fixed it

slender valley
#

Poor Link

tropic rock
#

It also simulates CD support

slender valley
#

I see, so this version wouldent work if you were to burn it to a rom chip then

tropic rock
#

nope

ancient thistle
#

I'm just hoping I can get my hands on a reflex adapt sooner rather than later. Not sure how often MiSTer Addons refreshes their stock.

I think @fickle folio is manufacturing some high quality overlays for Jag. Not sure what the progress on that is or if it's just experiemental funsies.

@shadow topaz - So in the video, mostly in the last few stages, there were some video glitches where your player was facing the wrong direction but still able to pull off moves.... and some places where the rope-with-spike thing would catch Goro but you'd get stuck until you let go. Are those bugs only present in the Pal version? Or also when running on NTSC?

#

I can verify that it does indeed work with BigPEmu... but I have zero skills and likely couldn't get past the first level. šŸ™‚

#

Or probably you don't also have an NTSC Jaguar to test with.

#

If I'm having issues loading carts with dual ram and retrotink 4k is it still recommended to disable direct_video?

#

Well... something not covered anywhere I noticed but just worked for me... Not only do you need to have CD Enabled set to No you also need CD Inserted set to No as well in order for direct_video to work.

#

It is still buggy but it worked to load two games and crashed on the third cart load.

mental briar
#

It works with direct video either way. Unless something has changed recently. I play jag cd hooked up to my tink

Lemme look

mental briar
#

yeah, not sure. Not having any issue here swapping between those two. Are you on the 25.12.15 build?

#

direct video over the tink is also fine in both cart and CD games

The new episode of the Atari Jaguar Game by Game Podcast is released:

The Atari Jaguar Game by Game Podcast: 33 - JaguarCD and VLM

It's rare, it's controversial, and it completes the Jaguar picture. Ā Atari's JaguarCD peripheral saw limited release after numerous delays, but was packed with a remarkable audio visualization feature called the Virtual Light Machine, and bundled with a non-trivial percentage of the Jaguar's total commercial CD library. In this episode, we...

Alright... let me retrieve it

mental briar
#

So what happens with direct video when you boot the jag core? Do you get anything? Does the Tink give you a "no input error" or is the whole screen black?

#

and what kind of screen are you plugged into

eager vine
#

I get the cd boot bios and menu every time. or if cd disabled the weird broken red bios and then menu

#

mister > rt4k > lg c1 oled

mental briar
#

the red bios is totally fine on first boot

eager vine
#

when the crash happens it's during boot and might get a flickering red screen then black or right into black

#

second memory chip is from taki. i have not mem tested it

mental briar
#

it's probably not that

eager vine
#

dual saturn core seemed to be behaving properly for a few hours of play

mental briar
#

where did you get your legal Jaguar backups?

eager vine
#

rhymes with ambient

mental briar
#

I mean, it kind of does

eager vine
#

lol it was a stretch šŸ˜‚

mental briar
#

they have a couple of sets. did you grab the htgdb pack? it is on there

eager vine
#

uhhhh let me look

mental briar
#

might be good to grab that if you havent, just so we are using the same set

#

you also want to make sure the bios database is enabled in update all

#

as the latest core requires a different biost than we had been using

#

"requires"

eager vine
#

they are j64

#

my bios did come from update all. I think but i will delete and run updater again

#

i noticed something in the bios changed because i had been loading cd_bios.bin

#

and saw the extra bootroms

mental briar
#

ahh yeah, you don't need to load the bios for CD games anymore

#

boot1.rom is the cd bios now iirc
