No amount of dancing monkeys will allow me to excuse the painfully long loading times …

#

That being said .. im glad the core exists ..

gloomy lotus
#

What bios are people using for the neogeo cd core? I did an update all and got the latest build, linux updated.. but when I try to load either a .cue or .chd I just get a black screen..

#

I have a uni-bios.rom and as us_bios.bin

south cloud
#

No UniBIOS, it's not implemented.

gloomy lotus
#

so for the original bios does it need to be named boot.rom?

#

i.e. rename my us_bios.bin to boot.rom?

south cloud
#

'neocd.bin' & 'top-sp1.bin' inside your NeoGeo folder are needed.

gloomy lotus
#

thanks!

south cloud
#

You're welcome.

gloomy lotus
#

Success!

gloomy lotus
#

Wait, so what happened with the old Neo/Geo core, it is only saying it can load cd images? .iso/.bin.. is that normal?? I know it used to load .neo files

#

the neo geo mvs/aes 23.02.23 is the version I have

#

is that one being deprecated?

bitter spire
#

You need to manually switch between CD, MVS, and AES in the settings.

gloomy lotus
#

yeah, but thats in the new neogeocd core.. the old .rbf I have doesn't let me switch

#

well I should rephrase that

#

it lets me switch but still only lets me pick .iso/,bin.. I can select AES/MVS

#

but it only says load CD Image

#

in the new neogeocd core it all works though

#

So I guess ill just use that core.. but strange the old one isn't working right

bitter spire
#

Right now the unstable Neo Geo CD core and the current stable Neo Geo MVS/AES core share the same settings, so editing one affects the other.

To fix this, go into the unstable core, change the system type, and then save the settings.

gloomy lotus
#

Ah

ocean phoenix
#

yeah, I use an mgl to apply a setname to change the new core’s internal name

#

Both cores can’t exist in the same folder so I made a new one within cores and dropped it on there, with no _ so the folder stays hidden when browsing cores

gloomy lotus
#

Any downsides to just using the new core and just stop using the old one? is compatibility for AES/MVS worse in the new core?

ocean phoenix
#

New core is in development so I would only use that for Neo Geo cd games

#

Until work is done and merged into a single core, best keep them separate

#

But to clarify, no harm in just using one. You may run into issues that aren’t present on the current latest in the official repo is all I’m saying.

gloomy lotus
#

even with the new core in unstable it still effects the settings though.

ocean phoenix
#

Yes, rbf files have two names effectively. There’s the file name and internal name. Both cores have the same internal name. So you need to use a mgl file shortcut to change that internal name.

gloomy lotus
#

ah, I see. thanks

ocean phoenix
#

Let me give you an example

#

I should upload one for the Neo Geo CD core to make it easier. But that one has the same idea.

#

That mgl file you want in your _core folder

#

And move the new Neo Geo cd in-development core to a folder named hidden inside your _core folder

#

Then rename and edit that mgl file accordingly so it points to the rbf in the “hidden” folder and give the setname something unique like “NeoGeoCD”

gloomy lotus
#

/media/fat/_Console/_neogeocd for example

ocean phoenix
#

No underscore

#

/media/fat/_Console/neogeocd/

gloomy lotus
#

oh /media/fat/_Console/neogeocd

ocean phoenix
#

Yes exactly

gloomy lotus
#

cool, thanks!

#

will give that a go

ocean phoenix
#

The _ is what tells MiSTer to display that folder in your menu navigation

#

Remove it and the folder doesn’t show up

#

Which is what you want since the MGL file is what you’ll use instead

#

Yeah, sorry this is all a bit convoluted

#

Please ping me if you need any more assistance, happy to help!

gloomy lotus
#

appreciate it! thank you

#

lol I remember renting MK3 for the Playstation and trying to morph to hit a load time every time. I was like WTF!?

ocean phoenix
#

where's the latest neo geo cd core?

coral granite
#

If anyone wanna play Metal Slug without slowdown, I made a version with Turbo mode

#

It doesn't work on almost any other game tho (Same as on a Real Neo Geo)

Is Dual Ram just vestigial now? I see it in the repo but it looks like it's unbuildable so my guess is it's just cruft that hasn't been cleaned yet.

Cheers! Was there not already one or even 2 overclocked neo cores? Or is this one specifically for the cd games? Regardless much appreciated! And as for ngcd loading it is terrible, but the logic was sound bsck then! Give the people an inexpensive way to play these unaffordable but amazing neo geo games. I was very close to buying one, but then heard of the cd-z and while waiting for that the saturn versions of kof became available and the lure of also getting the capcom stuff was too great! Playing on emulator you can reduce to loading times so much i literally never saw the monkey 😂 while such a level may be tricky on mister i assume and hope we do get to ode speeds in the end (which are like 75% faster or so vs the og loading times?) and then we can all make an per game choice if the downsides of the cd (also some animation cuts i think?) are worth it vs arranged ost, and some additional content. I really love being able to choose!

I had a NeoGeo CD back in the day. It was the only way for my brother and me to afford playing NeoGeo games. Both the CD console and the CD games had normal prices like other consoles, not the super high prices of AES or MVS.

It is great to play Samurai Shodown 2 on the Neo Geo CD Beta Core and finally hear those CD Audio tracks again. It brings back memories.

#

Now I just need those awesome controllers:

patent granite
#

Probably going to buy/build a daemonbite/byte adapter for PSX to use that on MiSTer.. whenever the NGPC core comes out

abstract birch
#

I imported two of the PS2 versions above and they are great. But here is a cheaper alternative. Similar clicky thumbstick with microswitch buttons. It will have a sticky rubberized coating you will need to take off with isopropal alchohol, but it's worth it. You can still find them on ebay and amazon brand new for about $15:

61yEEdGkrZL.png
#

I bought four of them. I prefer the PS2 Neo Geo overall, but the PDP versus above is very similar. Last I looked, the PS2 Neo Geo pads are going for well over $100 used. The PDP is $15 new.

patent granite
#

Price wise it is definitely better for sure

abstract birch
#

It also has the advantage of being USB so no need for an adapter.

patent granite
#

I am a little curious about that shape though

#

Why just one handle

abstract birch
#

It looks weird but somehow manages to feel natural.

#

There is an Xbox 360 version as well but it seems more rare. PDP Versus Fighting Pad.

#

No matter how I try, I can't figure out a way to make the Neo Geo CD core work. I know it is a WIP, but every game I launch (I have bin/cue files) the sound simply don't work. I have the bios (maybe it is corrupted? I dunno), I set the region to JP and the bios to Original in the OSD. is there something I'm missing here?

sonic solstice
#

Ok, this is almost assuredly not it, but I've somehow set core volume to zero before on a core and wasted half a day trying to troubleshoot it. Again, probably not your problem, but a good thing to check.

Do I need to make a seperate folder for Neo Geo CD?

Reminder: They have a rubberized coating on them that has degraded after several years (even new old stock) and it will feel gummy/sticky when you take it out of the box. You can totally remove the coating with isopropyl alcohol and some paper towels. For a very thorough removal takes me about 15 minutes. I've done this with four of these controllers (I stocked up).

Don’t know if anyone can help me but:

I’ve been trying to install the Neo Geo CD core. I got the WIP core, put it inside Consoles folder

Then I got the bios and put it inside Games/NEOGEO

Also got some bin/cue games.

When I try to load the games, everything seems fine. But when the games are running, I got only sound effects but no BGM (it keeps making a “click” sound, like a scratched CD). Curious enough, on the core media player every track runs normally.

Am I missing something? Does anybody has a clue or a tutorial that I can use to review my steps?

green marten
#

Also it’s the most recent core yes? Sorry…simple questions first 🙂

hearty fractal
#

@green marten I ran update all yesterday. About the core, I’m not sure. Where can I find it?

green marten
#

See above

#

@hearty fractal

I’ll try it now. Do I have to delete the regular core? And is there any config to be made inside the core?

green marten
#

You don’t need to delete the core that’s currently there no

#

Archive, a redump page. Any suggestions? Without link, of course

#

Also, I’m suspecting that the bios could the the culprit for the trouble. Where is the best place to get one?

green marten
#

No you should be fine with redump

hearty fractal
#

Great!

Funny thing: I installed the core you mentioned and everything went fine. Then I ran update all to get TMNT core and it installed some neo geo bios. Afeter that, the core doesn't work anymore.

# green marten No you should be fine with redump

The situation is this one:

  • the first time I run the ngcd core (after I “install” it ) it works fine

  • If I run the regular neo geo core, somehow the NGCD core just stop working. It opens the game, but the sound is gone.

I think it must have something to do with config or bios files (or maybe a conflict)

green marten

Yes, will do that asap. But, as you see, I’m a little lost here and I don’t know the dev GitHub page lol

#

All does games for ngcd go into NEO GEO or NEOGEO

patent granite
#

Games\NeoGeo just like the regular Neo roms. I made another subfolder in there called _NeoGeoCD to keep things separated/simple

languid quarry
#

ok thanks

gritty yoke
#

same as neogeo core

patent granite
#

Make sure you get the neo geo cd bios file

languid quarry
#

instructions on mister forun says NEO GEO so I just wanted to make sure

#

do you need both neocd.bin and top-sp1.bin?

patent granite
#

Yes

languid quarry
#

also my ngcd games are on usb hdd but my roms are on the sdcard

#

will that cause a problem or shoudl I move all my roms to usb0 as well?

patent granite
#

Not sure about USB HDD, I use a network share for the quickest speed

languid quarry
#

i see

#

still copying chd over to usb

#

only read my neogeo roms dir if both are on different places

hearty fractal
languid quarry
#

yes. I got everything running now but cd/roms are both on usb0

you havw to use mgl for cd if you want to have roms/cd in different places

is there any way to remove these types of ads from my channel? i was considering turning ads off completely after seeing that more than once recently

green marten

At least people are smart enough to know we don’t pick the ads because I’m sure some weird shit has run on my channel too

#

For awhile it was a lot of crypto shit

#

I dunno if I went “up a tier” but lately it’s been a lot of fashion brands. Which is hilarious because I had an ad for J Crew. Lots of retro gamers shopping there I’m sure 😂

Wait the ads are tied to the video not the user?

green marten

#

Interesting

green marten
#

like if you watch MY channel you are more likely to see tech ads because ad buys target specific demographics / audiences

#

so you get grouped into ad buys and genres

#

there ALSO seems to be tiered ads IMO. Like when I first started ads and my channel was small it was GARBAGE shit. Stuff ad buyers could get for nothing

#

as Ive grown the ads have become way more mainstream

inland drum
#

What i find mildly amusing is that the ads often come when you lets us listen for ‘30-45 secs’. Is that something you have control over?

The controller feels really nice especially with Neo Geo and Neo Geo CD games

Having not had any issue, I can’t really recommend any fix. Though if it’s only the one button, maybe it’s a bad microswitch? But since you just got it , might be able to exchange.

use a non case sensitive file system on the USB drive and you wont have the issue

best way is to copy the folder from the SD card

then you cant get it wrong

Yeah, a lot of sellers wont let you return an item if its been tampered with. But completely agree, was tempted to break out the multimeter to troubleshoot

I tried 2 games today, first the first time using the NeoGeoCD core I have to say, both games load, but even the BIOS Screen looks garbled.
The Fix layers produce the health bars in Fatal Fury 2, but I can't see characters or backgrounds. Same with Viewpoint.
Any idea? Some cache I need to clear?

#

This is how viewpoint looks, sound is fine by the way

#

Ironically loading screens look fine

#

Found the issue, was missing "000-lo.lo"
It seems the only 2 files needed for NeoGeo CD to work are "000-lo.lo" and "top-sp1.bin"

You make no sense. You just said Unibios and CDZ are not used yet.

nocturne storm

you can choose which system and which bios you want to use in the OSD. What about that makes no sense?

flat shard
nocturne storm
#

Those are the files. Nothing to do with the settings in OSD.

flat shard
#

OSD doesn't allow to select another bios, except UniBios which it doesn't use.

nocturne storm

Fact is you need the files for the CD and Bios system and there are two more file which are the CDZ and the unibios but those aren't running yet.

#

is this actually true. I looked through quite a few "issues" on the GH repo for NG and many of them exist in real hardware.

#

some of these "glitches" appear in the real machines

#

And I have not seen glitches at all

#

In fact I made testings with an AES and the Core... and all is behaving the same

fallen beacon
#

yeah that is why I asked

#

would be curious to know what cuavas is talking about

fluid idol
#

maybe old information base, but there were several glitches that have been open until recently

coral granite
#

Lol that was me

full raven
#

Neogeo core works the same with an AES or a MVS, depending which system you select.

#

It works the same speed

#

And has the glitches and overscans that the real games have.

nocturne storm
#

Any news when the cd will be public?

ocean phoenix
nocturne storm
#

That's a pity

ocean phoenix
#

I wonder what’s left to fix before it goes public. Im also hoping/expecting it’s an update to the Neo Geo core so that it just uses CDs. Personally, it would be nice if it mimics the TG16 core and has a dedicated NGCD folder for the games instead of expecting it all in the NeoGeo folder.

still gorge
#

If not, MGL is a thing

#

I think the feature most people want is turbo loading times right? lol

bitter spire
#

The CDZ features should fix that, but at the moment it doesn't work.

still gorge
#

I dunno anything about CDZ

#

how much better is it

ocean phoenix
still gorge
#

noice

#

you could just have "Load game" and "Load CD" or whatever as OSD options separate

green marten
#

Pulstar is a good example; garbage graphics on some transitions. So the FPGA core “looks” like it’s buggy but it’s actually SO accurate it shows you screen garbage on a real AES with a real cart in the machine

#

So sometimes “accuracy” means “looks worse technically” lol

still gorge
#

Yeah, in the original Legend of Zelda I kept freaking out over the choppy screen transitions in dungeons, turns out, that's just how the game is

fluid idol
#

I doubt that the vs screen in breakera revenge had those layer priority issues on real hardware.
At least that one was one of those that may have been fixed in the prooer releases now

full raven
#

these priorities are fixed

fluid idol
#

yes, but it was somewhat recently

Question on where to put CHD files for this core, can I put them in a subfolder of the main NEOGEO games folder?

Need to put it in a separate folder than the base Neo Geo core as the NGCD core is named the same.

I tested it out myself, and it loads up and plays like normal.

If it's a general issue with the core, then your core might be corrupted. Try deleting it and installing it again.

ocean phoenix

That and delete the bios files and use update_all to get them

Is there another neo geo core with turbo mode?

Or one that can run faster improving slowdown?

Works a treat with the Metal Slug 2 Turbo rom

It's kind of old isn't it

also, what's the purpose of 18 mhz vs 24 mhz

#

any chance this overclock option will be added officially?

lucid flume
# still gorge It's kind of old isn't it

Yes it's a bit old but it still works. It would be awesome if someone added an actual turbo option to the core. The 18 vs 24 is just levels of turbo to choose from. There are some minor visual artifacts with the higher option.

still gorge
#

Who do I need to pay

patent granite
#

How many Neo Geo games actually have slowdown?

lucid flume
#

Quite a few

#

Though most aren't really a problem. Metal slug 2 can mostly be fixed with the patched ROM without a turbo.

Depends if you like the original slow down or find it annoying.

Is the CD core still in active development? Seems like it’s been quite a while since we’ve seen any activity.

I don't remember exactly but I think that the cabal "port" works better with the overclock.

urban vector
#

I don't think Furrtek is going to work on NGCD again, if he was he has had years now to do it. I certainly wouldn't wait about for it, not with him taking on Super A'Can next. NGCD is nearly done now, I assume Paul has just been busy, and will finish it off at some point. Hopefully he also looks at adding support to the various unlicensed mappers after that, which are all documented on GitHub and seem to be fairly trivial changed to the code to enable.

It's good he doing Super A'Can as nobody else seems interested enough to take it on as it is such a niche system with a tiny library. I hope he pulls it off as it is one system I can't imagine I will ever even see, let alone know

its a meme system

#

the only reason people want it is its rarity

#

I would challenge anyone to name one of its 12 released games without using the internet to look them up

Hitler Monopoly

forest bloom
#

Thats not a released game for the system

urban vector
#

Oh yes it is...

forest bloom
#

https://en.wikipedia.org/wiki/Super_A'Can

Super A'Can

The Super A'can is a home video game console released exclusively in Taiwan in 1995 by Funtech/Dunhuang Technology. It is based around the Motorola 68000 microchip, which is also used in the Sega Genesis and Neo Geo. Twelve games have been confirmed to exist for the system.

#

not on wikipedia

#

so its some low rent homebrew at best

#

the core would be the same as the gameduck. Most would launch it once then never again

urban vector
forest bloom
#

thats not called Hitler Monopoly

urban vector
#

No, but you weirdly can play as Hitler

#

Not saying this game is good, but for all the wrong reasons we know it exists

forest bloom
#

looks like its incredibly poor taste

urban vector
#

No shit, it's Monopoly where you can play as Hitler. Although I suspect at the time they thought nothing of it

#

There are a couple of RPGs on there, although one hasn't been dumped yet sadly. But it is possible once there is proper emulation of the system people may look at localising games for it.

#

There are platformers too that look OK, but obviously not as good as Sonic or Mario etc.

forest bloom
#

highly unlikely its a meme system due to rarity. Even if its done it will be at best fired up once and disgarded

#

if someone wants to use their time doing it let them but it seems a futile waste to me

urban vector
#

As it stands there is no proper emulation for it, Mame has poor implementation and has no sound, so his work will mean that the system is finally emulated.

forest bloom
#

Mame usually doesnt have sound when something is protected

urban vector
#

If Furrtek wants to take this on as a challenge then good on him, his time to do what he wants with.

forest bloom
#

I havent seen him post anything about it

urban vector
#

He did a big announcement

forest bloom
#

when

urban vector
#

We have a channel about the system you can read all about it there

forest bloom
#

nothing in a month from his twitter and I havent bothered scrolling back further

#

found something at start of may but he is tracing the sound chip

urban vector
#

Copy and paste isn't working for some reason, but just look in MiSTer cores for Super A'Can

#

no mention of doing the system

Have pinged you in the chat, you can read all about it, it is his next big project after Turtles

forest bloom
#

he doesnt mention doing it at all

urban vector
#

Jesus Christ

forest bloom
#

just that he is wanting to document the system

#

absolutely no mention of writing a core

#

Talking about the future: the subject of my next Patreon-supported big reverse engineering project will be the ✨ Super A'Can ✨.

It's an obscure Taiwanese home console inspired by both the SNES and the Genesis, designed by a subsidiary of UMC (a semicondutor giant well-known at the time for their 486 CPUs and clone Famicom chips). Because it was released near the end of the 2D-era, sales were minimal and only a handful of games were officially released before everything vanished from stores. The remaining stock was allegedly sent to recycling, or maybe just a landfill (another Atari E.T. story ?).

I had previously imaged both of the console's custom chips, the UM1618F (video) and UM6619F (audio and IOs), but the pictures turned up to be almost useless because of how small the silicon features were.

The dies were sent to John McMaster, who was able to produce much better images of the UM1619F chip. After trying to identify cells for a few hours (see picture), I was confident that reverse-engineering was possible even though the internal structure (ie the individual transistors) of the cells still couldn't be seen.

In contrast to all my previous silicon reverse-engineering projects which only brought confirmations, minor details and information for cycle-accurate emulation, this is undoubtedly going to be largest and the most helpful regarding preservation of all, simply because so little is currently known about the system.

This long project's first goal will be to extract the schematics from the UM1619F, extract its internal ROMs, and document how every bit of it works.

Now is the time to either jump ship, or to climb aboard this new adventure 🙂

#

is his patreon post

#

no idea how you read that as I will be creating a core

#

he seems to want to document the system

lucid flume

He's opening the door to it at any rate.

metal gear 2 though is supposed to slow down

#

thats how it is on a real system

coral granite
#

A lot don't want it to slow down

#

So I made patch

urban vector
#

Well maybe we are all reading it wrong, but "reverse engineering" implies more than documenting, and he has said the first step of this long project is documentation and ROM extraction. He has also asked for a system and talked about test ROMs, so is implied he wants to do more than just document it. If someone who has him on Twitter fancies asking him to see if he does hope to make a core that would clear things up.

forest bloom
#

no he likes to reverse things

#

this info is then used by others

#

test roms are needed to verify his documentation

#

The sound chip is unknown currently so its an interesting technical challenge for him

urban vector
#

Well we will have to wait and see then, but I can't see him wanting to spend a year "reverse engineering" something and not using it for anything, when he is coming off the back of reverse engineering TMNT and using it to make a core. Will have to see though, maybe someone with Twitter can just ask him

lucid flume
urban vector
#

I didn't see that if that is the case, do you have a quote?

lucid flume
# forest bloom metal gear 2 though is supposed to slow down

Sure. It's pretty egregious though and it's debatable if the sheer amount of it was intended or not based on the bug in the code that causes it. The patched ROM just fixes that bug and makes it a lot more playable. The turbo makes it a much faster and frenetic experience. It's nice to have options.

forest bloom
#

it was released though like that so they must have known

#

or just ran out of time

lucid flume
lucid flume
#

Impossible to know.

#

Interviews with original devs would be so fascinating.

urban vector
#

Regarding future work on retro hardware, I'm planning on letting go of specific platforms to focus on original chips and boards, leaving the porting/adaptation work to others. This is solely because I prefer reverse-engineering and creative work than anything else. As I've written before, money is one thing, but a big part of my motivation is derived from the excitment of discovering new things and understanding how they work.

In the following months I'll list the chips and systems that are within my reach for reverse-engineering. I'll make it clear that I won't be writing cores for specific FPGA systems in the future. I'd also like to change the pledge tiers to allow some of you to decide on what I should work on next.

lucid flume
#

Yes that's the quote I had in mind. I was just searching for it as well.

urban vector
#

Oh well, that's a shame he will be doing all that work but not making a code at the end

forest bloom
#

thats what I said. He loves the technical challenge

urban vector
#

If that's what he wants to do then fair play to him

forest bloom
#

Mame will use his info

#

and if anyone want to dev a meme console they will have it too

lucid flume
#

The work won't go to waste. He's been involved with tracing chips for a few recent cores I think.

forest bloom
#

The info wont be lost

lucid flume
#

A mame meme

forest bloom
#

Many of these obscure consoles are not much more than memes

#

there is generally a reason they failed hard

urban vector
#

The problem is there aren't many people who can take a trace and turn it into a core, so it is a very small pool of MiSTer Devs who can make use of them

forest bloom
#

not jsut for Mister devs

#

the internal rom from the chips will be useful in Mame

urban vector
#

Yeah I expect we will see Mame improvements from his work

forest bloom
#

and lets be honest the number of people who want a cycle accurate super Acan is tiny

#

other than for dick waving rights

urban vector
#

Well by the time he has done all the work there won't be many doable consoles left on MiSTer so maybe someone will find it an appealing challenge

forest bloom
#

if it wasnt for its rarity and current extreme cost it would have been forgotten a long time ago

#

I dont buy that argument, Devs do it for their fun, not just because there is nothing else to do

#

a Super Acan is a few weeks/months for almost no benefit

#

or so someone can play your Hitler Monopoly for a Meme Youtube video

urban vector
#

My understanding is 3DO isn't super well documented and would be a hell of a lot of work, and is complex like PSX. Super A'Can would be equivalent difficulty of the SNES core, so no joke. Maybe having the chips done makes it a lot easier for someone, I am no Dev though

forest bloom
#

That 3DO guy stated they were well documented

urban vector
#

Yeah, maybe they are but we never saw any links to them

#

I think they may not be public

#

There certainly hasn't been any linking to a wealth of documents when 3DO has come up in the past, which is weekly

#

We have plenty viable arcade cores, to have people focusing on the remaining consoles, besides the ones already in development IMO.

patent granite
#

I really do hope more arcade cores becomes a thing

limber ferry
#

Viable mister successor, unless developed with this in mind, is far down the road. People think "CPS3 is a waste" because SF3, but other boards use the SH-2 chip.

patent granite
#

I want Warzard tho 😄

urban vector
#

It's all down to what Devs are interested in, quite a number seem only really interested in consoles / computers / arcades as that is where their interest lies

patent granite
#

They are interested in what they are interested in, I have stuff to donate but no one wanted it. Just gotta go with the flow on development if you cant code

limber ferry
#

Happy with the current landscape. Plenty of people working on interesting stuff.

patent granite
#

Every chip that gets figured out and coded makes it easier for someone else to implement something else

#

It's a good process

Plus cores will be ported to other devices once we have a bigger and affordable successors.

is a 3do core being in developement ?

patent granite
#

I think they would have to be pretty significant payouts to motivate any developers to take the task on

#

As annoying as it is to me that a 3DO core could be done before worthy arcade pcbs, I have to admit that Japanese and Korean kusoge library for the console is tantalizing

#

Well, I don't. I certainly wont complain about developers being paid either

#

I used to donate heavily to fpga dev patreons, a few years ago

#

At this point, if I had the $ to do it I would.. for almost all of them

#

My only gripe is when stuff gets paywalled, even if its only temporary

#

That kind of veers into conversation territory of "What is better? A motivated dev doing it for free or a paid one"

#

And I dont really know

#

That isnt exactly my favorite source of cores to begin with

#

But as always

#

Beggars cant be choosers

#

Oh good, so it'll be like the French Revolution. We'll guillotine all the devs, and do it ourselves, but better

Except itll be worse

#

Okie

limber ferry
#

I seriously don't get the Jotego hate. The guy provides documentation for preservation and emulation improvement in general; part of the patreon supports other devs like furrtek; part of it employes people that looks like they truly need the work; plus he's supporting a lot of platforms at once. Still it looks like it's not enough for some "because he holds betas". SMH

#

Besides, as much as I apreciate some cores that are focused on "making games run" I like his approach on documenting and having it as close as possible to a 1:1 replacement of original hardware.

people who hate on jt are the most common type of nihilists.

Just wondering if someone can help me with the latest unstable Neo Geo core. I've downloaded it and transferred it to my Mister. I've created an MGL file pointing the new core to "NeoGeo-CD" (located at /media/usb0/games/NeoGeo-CD). However, when I click to browse for a *.cue file, the browser opens the standard NEOGEO folder which I've to back out of, and manually navigate to "NeoGeo-CD". It's as if the MGL file isn't being read/used. Can anyone give me a tip re fixing this?

Did you have setname configured in the mgl?
I'm not sure about neogeo specifically but that's used to set the game folder/config file names used

Last time I had this discussion it was "because he doesn't use the Mister Framework". I thought it was a non issue, since he already supported other hardware. Bashing on DEVs, the people who are working on this(as a hobby, for money and fame, whatever the reason), is a fast track for drama and I'm assuming we all know where this leads to.

patent granite
#

Devs are wonderful but not above reproach, disagreeing with the practice of paywalling betas is not really that hot of a take tbh.

Doesn't mean the person saying that is resentful of their work, or ignorant of the finer details of the situation.

@patent granite Not pointing the finger to you, but it's quite easy to find jokes about JT around here. We all know it, let's not pretend the place is immaculate. And come on, a 3USD "paywall" to have beta access for cores, for a hardware that costs beyond 200USD. Is it really a "paywall"?

People are willing to donate to core devs

3 dollars and getting a beta core that eventually will be released to the public is a steal in my opinion

Instead of asking for a core y’all in the 3DO community need to change your tactics. Have you tried convincing them it’s worth the effort.

it's true it has the best SSF II Turbo until DC version appeared.

#

Road Rash is fantastic

#

but.... there are a lot of BAD games there.

#

but there are a feeling in the console that it's that... a feeling.

#

the feeling of power in 1993

#

These are

#

PC games

#

how to say

#

it was a way to play these PC games in consoles

#

It was a time of some FMV and strange games like Cyberia... The future of RENDER and FMV !

the amiga was a personal computer ! 😅

#

yes yes

#

I remember flashback in the amiga

#

Alone in the Dark I don't know the performance in 3DO

#

I didn't test

#

I think it could be possible

#

Motorola 68000 was created by an entity of liquid light in the beginning of the creation of the Universe, so... it's possible that an amiga version could work well.

#

3DO has feeling

#

but

#

Megadrive was FUN and had the blast processing from the origins of time.

#

I would like to see a 3DO core, that's sure.

To be honest they could have done it back then. It's just lack of effort. After playing around with some 3do graphic stuff and a guy with development... I see why some devs produced top-tier looking 3do games and others... Not so much

it runs choppy

#

it has all the animations

#

the zoom perspective is correct

#

but the framerate is terrible

#

it depends on the stage

#

when selecting the game options "no weapon" the game runs better

#

and when you finish the game... the input name of the arcade appears ( but you can't move it ) the AES credit counters appear at the screen ( they are not in the game )

I don't notice the chop that much. Either way, hard as hell. Ill never beat it

then, you see the ending screen, then you can enter the name in another input name score.

compared to the original version in neogeo... 3DO version becomes a very bad experience in gameplay overall.

it is playable

i can't say it's not playable

but the experience is lost in many ways

compared to an SNES or MD versions... of course the game was better.

opal badge
#

Maybe not as smooth. But I wouldn't say "very bad" . Maybe in comparison to the cartridge mvs, but in comparison to the NGCD.... I'd have to take the 3do version any day

#

The 1x drive in the ngcd kills it for me. Awful load times

full raven
#

well

#

If I have to try to play this game in 3DO or NGCD... I try NGCD.

#

not a very long loading game.

#

10 secs per round

#

not bad

#

3do version has small loadings here and there.

#

6 secs for a round start

opal badge
#

The initial load times are incredibly long. And the small bursts last longer on the ngcd version than the 3do.

#

Honestly the loading times could have been zero on the 3do version. It's not that hard to accomplish, just a little extra work.

but it lacks something that makes it not full compatible with 68000

So is it a personal preference thing for a dev or an objective outcome of little reward across the board? If someone's not interested, they're just not interested. Sounds like a personal preference thing to me

Its both. A dev has to have the interest to do a core, Ie like the output enough and if there is a compelling SW collection then its easier

hi. I put my games on my hard drive, but the core doesn't seem to look at the hard drive. It defaults to the fat directory. how do I make it find the games on the hard drive?

All my folders are on the root, according to the instructions I was given when I set it up 2 years ago. Most of the other cores find them fine. hmmm. Maybe I'll make a games folder and move all the other folders into it.

Because you have the actual hardware and want to use it? I was never sure why the price was so high, I mean some is markup but, anything neo geo is expensive. even the newly released games tend to be at least a few hundred for a cart

I'm trying to help a friend diagnose his MiSTer system remotely. He's getting credits rung in, sometimes, when he hits A (button 4 on the panel). It doesn't happen with any other core.

I have NeoGeo and I got the first NeoSD. Not bad, but not nice. The first NEOSD loads so long and it can fail when loading... The firmware is not updated anymore and basically they abbandoned it so fast.

#

I play NEOGEO in MiSTer the 90% of the time. The feeling is exactly the same.

#

I know NeoSD pro has a RAM slot for fast loading and allows to use the NEOGEO CD games on it in a strange way of using ADPCM-B as CD-DA Mono Streaming.

#

I never tried this NeoSD Pro and I don't know how the NGCD sounds on it.

Love it. What's the scanning process like for this? Most of these materials are 1' x 1' right?

Basically they have to be scanned in piecemeal and stitched back together in photoshop using a tool called photomerge, and then edited and cleaned up

@limber atlas - thanks, deleting the config fixed his problem. 👍

Oh, neat. I was digging through a box of old LDs the other day and found a bunch of NeoGeo discs, along with a few others I forgot I had. PC Engine promo disc, and a couple of MegaLD LaserActive discs.

Is there a reason you're not using a camera for this instead of a scanner? Much faster and larger. I was asked to do some large paintings for city council here, and a camera makes that super easy. Also for scanning. I used a little Olympus to do 200 pages of Japanese tech magazines much more quickly than a scanner could.

#

Or is it a matter of using what you got?

wary bronze
#

For documents, a scanner is still the better option. Consistent and even lighting that never changes, DPI controls for various capture types (1 color bitmap vs 24 bit), etc.

For paintings, I agree: camera all the way.

olive garnet
#

I figure the lighting can be controlled easily enough if you've got the gear (I'm a photographer, I have scads of lights) and the format is infinitely variable, so... not sure how that factors into it. Speed is also a factor, plus I don't have to un-bind any books to photograph them, where a scanner demands it.

#

but yeah, there are advantages to scanning. Cost and setup time is a big one.

wary bronze
#

All you need is a flat surface and patience 😄

olive garnet
#

The former I got! The latter, not so much. ^__^

wary bronze
#

Dating myself, but back in the early 90s we still used cameras to capture linework for comic book publishing. You then create press plates from that.

Scanners made all of that soooo much easier.

olive garnet
#

Undoubtedly.

#

I used to make business cards and print 'em double-size on 300dpi laser printers, take them 'camera ready' to the print shop and they'd reduce them 50%, getting 600dpi in the final.

Thanks, I'll look as soon...

#

Are all the games working now on regular speed or are there still issues?

south cloud
#

I've done some extensive tests just before (fullset in CHD format).
The Neo Geo CD system seems to work as intended now., if you use the 1x mode.
2x,3x and 4x speed-up options could give some errors when loading games, like a frozen progress bar.

I've tried : Magician Lord, Ninja Master's, World Heroes 2, World heroes Perfect & they are working perfectly (with music, sfx and all).
Neo Turf Masters is correct now with the announcer voices (I've tried some courses, addicting game).
Portaits are rendered correctly on SamSho III, and sounds are correct on that game (SamSho IV too now).
RBFF2 is working as intended , no more incomplete portraits and we have all sfx, sounds and music working now.

I have a doubt on Gowcaizer SFX, I don't have the original game anymore for comparing with an original system (some SFX seem to be missing).

#

EDIT 2023/06/29 : After a rapid test on the whole fullset, the speed increase option seems to be more stable with the CDZ BIOS/Uni-BIOS. Only Twinkle Star Sprites crashed on my system with 4x speed on initial loading.

For the Neo Geo CDZ system, some games refused to work (like the two Last Blade ones with the Redump set).
It seems only the CDZ protected games are locking during the end of the boot process and we will need to test the core once more with patched/cracked versions of those games.
EDIT : Use either the UniBios for bypassing the protection or a NeoSD Loader set (already cracked).

#

Samurai Shodown RPG works, I repeat SamSho RPG works now. 😁

#

I've not tested the Unibios system, so I let others do it.

the 4x speed is the same speed loading as NEO CD SD LOADER

I don’t understand why 2x isn’t working on all games. I have a CDZ and its drive is 2x vs the regular console. There are no compatibility issues. Why is it different on the core? Inaccuracies?

austere nymph
full raven
#

by now, CDZ is a bit unstable. If you want to get games non patched working the Unibios is needed.

fluid idol
#

Wasn't cdz still 1x but with a larger cache?

south cloud
#

2x CD drive as per specifications.

#

So, I've done some further testing today.

#

1x works well only with Neo Geo CD BIOS, some games block at 87-88% on the initial loading time with 2x and further speeds.
2x works well only with CD Z version, otherwise some games will freeze with 1x.

#

For the games which won't load on CDZ BIOS but work with a classic CD BIOS, the games are copy protected on CDZ systems.
You must remove the CDZ protection on your BIN+CUE or CHD files.
Some later games (MS1, MS2, LB1, LB2, KOF99 at least) have also some checks inside the game for copy protection, you need to remove them too.
EDIT : That could be done with a Uni-BIOS CD or a patched/cracked set.

olive garnet
#

CDZ -real hardware- had double speed sequential loading, but the seek time was just as slow as the original drives. Any game that loads all at once (Viewpoint, Puzzle Bobble) is really quick. Any game that isn't well optimized and does a lot of seeks doesn't benefit nearly as much.

south cloud
#

I can confirm that we could patched versions if we use the CDZ BIOS, for some protected games (same set as for the NeoSD Loader).

#

Or, the UniBIOS as GOEMON said earlier.

limber atlas
#

So I guess UniBios is the way?

south cloud
#

As you like, there are two ways for the same goal.

#

I chose the "patched" way as I already have done a fullset for some friends with their NeoSD Loader.
And I keep the original BIOS loading screen.

what is the maximum number of tracks a NGCD game can have? I notice some Redump images don't work unless you convert to single bin cue

Which game doesn't start and have a lot of tracks ? I'm not sure the issue is related to number of tracks

shy bane

it is part of CDZ protected game

full raven
#

In Archive.org there is a set of unprotected games for NGCD and CDZ.

shy bane
#

Right but just merging into single bin/cue wouldn't address copy protection. That's what it took to get it working. I think I just need to delete and reset all my Neo Geo files. I don't get any audio if I use UniBIOS and if I choose the original Neo Geo core it no longer allows me to select AES/MVS roms. It just looks for CD images

bitter spire
#

I wonder how accurate that list is, because I have protected copies of games that boot up just fine while using CDZ.

Maybe some games in the current build are affected but not others?

tepid plank
#

they boot,but after some time they break.

#

you get some text on screen then

south cloud
#

That's why you need to be sure to patch the two copy protection methods.

shy bane
#

Thanks for the help everyone. Clearing out my Neo Geo config files fixed the main core. I'm gonna setup a MGL for NGCD so I can save those settings without impacting the main core. Plus, audio is working now with UniBIOS 🙂

south cloud
#

Did you use the CD UniBIOS version ?

#

It's different from the AES/MVS one.

How is it named on your configuration ?

Ok, perfect.

So, it's not a 'simple' error there.

Neo Geo CD

The Neo Geo CD (Japanese: ネオジオCD, Hepburn: Neo Jio Shī Dī) is the second home video game console of SNK Corporation's Neo Geo family, released on September 9, 1994, four years after its cartridge-based equivalent. This is the same platform, converted to the cheaper CD format retailing at $49 to 79 per title, compared to the $300 cartridges. The ...

According to this article CDZ was actually the third revision

But it’s the only one with a double speed drive

I can’t get games to load on the core if I set CDZ & UniBIOS

Only with CD & UniBIOS

#

I’m also finding the core very unstable when changing games. Half the time it just crashes leaving me with no video or sound. Have to power cycle the MiSTer

Makes testing all games quite tedious

For me switching games causes the music of the last game to continue playing.

Everything works perfectly here. Didn't have any issues switching games or Cdz with Unibios. The only issue is using 4x speed with the normal bios, the loadings gets stuck at the end, and then goes normal switching back to 1x. Using Chd images here. Tested about 30 games so far, works great. Double Dragon is missing sfx and voices. Super Sidekicks 3 grafics glitches after the first goal seems to be fixed too. I'm using uni-bioscd.rom 3.3 and 000-lo.lo cdz bios
