[slow grail]

I would delete the bios files and turn on the bios database in update_all's settings. That's the bios I am using

[twin forum]

Ok

[twin forum]

Alright, did that, i just get a black screen when i launch the rom

[slow grail]

do other roms work?

(just want to make sure the bios is working)

and do you have those 4 files in games/neogeo

[twin forum]

Regular roms seem to work. Just the hacks that dont

[slow grail]

whats the sha1 of your CVS Plus rom?

[twin forum]

Let me see

My sha1 is different

da39a3ee5e6b4b0d3255bfef95601890afd80709 SNK Vs. CAPCOM Plus (hack 1) (svcsplus).neo

[slow grail]

hold on, I have another svc plus rom

[twin forum]

this is the super plus hack

my svcplus is the same sha1

[slow grail]

hmm, I have both hack 1 and hack 2, but i think the shas are different thejesusfish@mini Xbox % sha1 /Volumes/MiSTer/games/NEOGEO/4\ Hacks/SNK\ Vs.\ CAPCOM\ Plus\ \(hack\ 1\)\ \(svcsplus\).neo SHA1 (/Volumes/MiSTer/games/NEOGEO/4 Hacks/SNK Vs.

[twin forum]

looks like your svcsplus.neo is a different sha1 also

hmm

[twin forum]

this is very annoying, i guess i have to track down a different pack

[slow grail]

look for htgdb 😉

[twin forum]

i did, thats where i got these

2023 files

[slow grail]

weird, that's what mine are too

[twin forum]

i found another pack with neo files, gonna see if those match

yep, the ones from this other pack match yours

[slow grail]

working?

[twin forum]

yep, this one works

weird

[slow grail]

We count those as wins

[twin forum]

Heh. Thanks

[twin forum]

these games on a crt are magic

[slow grail]

the neo geo core is one of the reasons I own a mister

[twin forum]

do you happen to have a good way to fix overscan on consumer crt?

seems like the games are a bit wider than whats displayed on the tv

i see in metal slug the HUD getting cut off

[slow grail]

oh huh

let me go look actually

I wonder if you set it AES mode if that makes a difference

[twin forum]

i think aes does fit

its mvs mode that doesn't fit

but i don't want home console mode personally

limited credits and all that

[slow grail]

I think this looks ok?

I can test another set, though

[twin forum]

load up mslug5

the hud is closer to teh edges

i'm also noticing life bar cutoffs on breakers revenge

nope, actually i see the same thing on aes

[slow grail]

yeah, I am seeing that too. It is likely just how it was on TVs. Arcade games are notorious for being naughty on consumer CRTs, and it wouldn't surprise me if AES games had similar issues (since they were largely just arcade games)

[twin forum]

hmm

i wonder if it has to do with the clock nto being at 60hz

[full raven]

what is the problema ?

[slow grail]

Ruckus is learning about the joys of accurate arcade emulation

[ocean phoenix]

It’s because CRTs in arcades weren’t consumer CRTs and likely didn’t have to contend with major overscan issues.

[twin forum]

were those more like pvms?

[ocean phoenix]

Dunno, all of them were different. But arcade games didn’t need to contend with major overscan issues like consumer sets. Also older sets had overscan issues or if their monitors were replaced. I’ve seen a lot of arcade games with HUD bars practically offscreen.

What you are seeing is very normal and expected.

[twin forum]

i dunno what you mean they didnt' have to contend with them, is it because they were designed/calibrated not to overscan?

[fluid idol]

They were as good as the operator gave a fuck when switching out games

[limber atlas]

No

[full raven]

The hud is normal like that

a real AES behaves in the same way. a little portion can be lost

[chrome umbra]

Also arcade monitors have exposed chassis where you have access to physical pots that would adjust vertical size, and width coils for horizontal picture size. I often have to use them when dialing in a tube-swap or chassis rebuild on my arcade cab monitors

[abstract birch]

I'm planning on picking up a Bror like that soon for my 27" trinitron. I see you ahve some controllers mounted on the side, are you using the Skadis pegboard or something else? really like your setup, very clean look

[slow grail]

Ya, skadis. There are clamps you can 3d print I think. I still am not happy with all of these since the controllers can fall out of them. But yeah, it’s a clean look.

[ocean phoenix]

Why do you have the N64 controllers at the bottom?

[slow grail]

to protect them. they fall the smallest distance when I move the thing

[still gorge]

N64 always seemed like a bottom to me

[ocean phoenix]

bottom in sales!

[twin forum]

that is awesome, what cart and hwo did you do this?

[slow grail]

ikea bror cart

[abstract fractal]

It's the quickest distance to the top of the trash can.

[fading cape]

Are a lot of those NSO controllers?

[slow grail]

yeah, the nes, snes, and n64 ones are

[fading cape]

Thanks

Maybe I should purchase some 🤔

[slow grail]

I really should just get reflex cords for everything. pull the real controllers out of storage

cords are just such a pain

[south cloud]

Too bad the NES ones aren't USB-C (for charging).

[slow grail]

yeah, they charge via fucking joycon connection. nightmare stuff

[south cloud]

I had an eventual deal yesterday for some brand-new Famicom controllers.

And said finally no, because of that Switch connector only (and I don't want to buy a charging dock station).

[haughty veldt]

You can tell just by looking at them!

[fading cape]

Not if you’ve never seen pictures of them before

[fading cape]

Okay, I’m out 😅

[haughty veldt]

Just the NES ones!

[fading cape]

Okay, I’m half out 😅

[haughty veldt]

Honestly, my personal favorite of the NSO controllers is the Genesis one. The build quality is way better than any of the other modern recreations of it. Including the ones that shipped with the Genesis Mini console.

[fading cape]

I’m lazy and just use the M30. It’s close enough

But very different side by side

It’s kind of become my default controller tbh

[slow grail]

yup, I use it almost everywhere as the default controller

[fading cape]

I hate it for SNES/PSX, but it’s great for most other cores

[haughty veldt]

I just really like using the NSO controller for Genesis/Sega CD/32X. I use the M30 for a lot of other stuff though.

Or for 6-button games.

But that classic Genesis 3 button controller injects the nostalgia directly into my veins!

[fading cape]

U old

[chrome umbra]

quesion about the NEO-GEO core. On a real NEO-GEO MVS, you can set global options in the BIOS like freeplay and mute attract mode for all carts/slots. The NEO GEO Mister core seems to already have the freeplay enabled, but can you alter the attract volume somewhere like you can on the original machine BIOS?

hrmmm this may be what I'm looking for, will have to try this and see what options are in there http://unibios.free.fr/howitworks.html

[full raven]

Exactly the same

[chrome umbra]

How can I keep the cabinet settings the same for every NEOGEO rom? They only seem to save per game which seems pointless when each game has its own soft dips already. The cabinet dips should override all game soft dips.

[full raven]

I think there is a backup ram per game in the core.

I proposed an option for global memcard, backup and single.

[placid granite]

you have to save these per game. just the one time though.

[chrome umbra]

That’s unfortunate. The whole point of the cabinet settings is that an operator could set them to apply to any cartridge played on the machine.

[placid granite]

Sure but this is a different system. But someone with development knowhow could implement it.

[ocean phoenix]

Maybe set it to one game and use symbolic links to copy it for every other game so if you change it for one you change it for all?

I should try that.

[chrome umbra]

What's confusing is that the core is already implementing global freeplay, where is that setting coming from? Is it internal and non-changing?

It's as though the devs want the arcade machine just to act like the console when there are significant differences in context and implementation

some of us have original NEOGEO arcade machines that we really want to use Mister for in place of the various multi-carts out there

[ocean phoenix]

I think the implementation is setup like a single game arcade machine and not a multicart one.

[chrome umbra]

I dont think so, if that were the case there would be MRA's for every game, like other arcade games

[ocean phoenix]

Why would there need to be an MRA? Genuine question.

[chrome umbra]

to associate the game with the core

plus the other things you can do with MRAs for any rom

[ocean phoenix]

It’s all the same hardware for every single game so the functionality differences you need to account for with an MRA doesn’t seem to be necessary. I’m no expert here,

[chrome umbra]

however you also have to deal with coin-up, settings per game etc. So it's architecture looks like a console, but plays like an arcade game......except when it's the console version 😆 it's a weird edge case really I guess

[ocean phoenix]

Yeah, I think it would be much nicer to have like a bios save if you’re using the arcade switch.

[chrome umbra]

I just want a mister-based replacement for the 161-in-1 carts for my cabinet that has all the same functions of a regular MVS system

[ocean phoenix]

That sounds awesome

I have an AES system, with our powers combined lol

[chrome umbra]

i'm just moaning because I'm too dumb to work out the solution

[ocean phoenix]

Not at all friend; you’re demonstrating a great use-case on how this could be improved.

my problem is that I’m too complacent in jumping through hoops to get shit working the way I want lol

In reality it should be as simple to setup as possible for everyone

[chrome umbra]

for that to happen I think NEOGEO arcade needs to be acknowledged as different than console, the same way NeoGeo pocket is. Although they share many common attributes, they are different.

[bright magnet]

I guess a workaround might be to use MGL files as the game list?

[gilded karma]

Isn’t the global freeplay just something you can change per-game in the service menu, the one with the white text? I am away from my mister

[chrome umbra]

having to change/make anything yourself for 160 games is completely missing the whole point of a multi-game system

imagine having to define controller keys for every NES cartridge you plugged in

[ocean phoenix]

This is what I do. I use setname to define a “neogeo_mvs” core config and set that up as an arcade machine.

But having to do unibios per game is a pain lol

[bright magnet]

It would be nice to have an MVS core, then we could have the “Game Select”, but the games wouldn’t all fit in ram so wouldn’t be a nice quick swap like cabs. ( have an MVS 4)

[ocean phoenix]

Ohhhh like hitting the button to swap games?

I think I’m the extremely rare Neo Geo fanatic that doesn’t know shit about the arcade games and only knows the console lmao

[chrome umbra]

In my arcade I have 22 machines. I set them all to mute for demo/attract because it gets wayyyyy too loud in there otherwise. Having to mute 160 roms separately for one system is cray cray. 😜

[ocean phoenix]

Yeah, totally understandable. I’m going to see if that symbolic link idea even works later today.

Also I’ll try to put in a feature request to be able to have the bios settings be a global thing when you’re in arcade mode in the core instead of being per game.

To your point @chrome umbra I do approach the core like a console lol.

[chrome umbra]

Yep, the core is amazing, but it's just having a bit of an identity crisis not knowing if it's a console or arcade core

I agree that it's 95% console, with a few arcade quirks like coin-up. That being said it should be universally configurable like a console

[ocean phoenix]

I wish I had a Neo Geo cab

I have the console and games but a cabinet is out there and front and center, much easier to get a game in

Plus it looks cool as hell

[chrome umbra]

when they aren't beat to crap, which most are. Had to do a lot of work to mine

[ocean phoenix]

I almost bought that Neo Geo mini arcade so I could put a MiSTer in it and do what you’re doing. Not the same obviously but it’s a lie im ok with lol

[chrome umbra]

I'll take mister over 161 carts any day of the week

[bright magnet]

Can relate, my mvs4 board is currently borked.

[ocean phoenix]

I think you guys with arcade machines are cool as hell.

[chrome umbra]

I got lucky, my 4-slot works, no corrosion at the battery site (did the remote mod) just the volume slider is dead, fortunately it stopped working on quite a high volume so I put a pot inline to bring it down

[chrome umbra]

we are mostly grumpy old guys who spend all our time working on them and hardly playing them

I put in a bug-fix for proper cabinet settings

https://github.com/MiSTer-devel/NeoGeo_MiSTer/issues/236

[unreal swallow]

where do individual per-game bios settings get saved?

[placid granite]

With MRAs you can make and save settings independent for every game.

[placid granite]

I think it creates a sram file somewhere

[fickle hollow]

Weird, I keep having random audio distortion on the Neo-Geo core using analog audio w/ 9.2 board; most of the time it's fine, sometimes there's a clear starting point and from then on audio is distorted until I reset. Sometimes it affects sfx+music, sometimes just sfx

before I bother everyone with a report, is it a known issue? is it normal?

[slow grail]

It’s not normal, and might be the 9.2 audio bug we have been chasing. What games? I’ll test when I’m at my desk later this morning.

Are you using just hdmi for video? If so, do you still get sound distortion if you set vga_mode=svideo in your mister.ini?

[fickle hollow]

It's mostly happening with Metal Slug/Metal Slug 2, but those are the games I play the most

I'm using a VGA > Scart cable

Would it still work if I set vga_mode=svideo?

[slow grail]

ahh the vga_mode is set to RGB then?

it would not 🙂

[fickle hollow]

I can do some tests later

[slow grail]

loaded it up with RGB set. I will see if i can hear it

[fickle hollow]

It's mostly random though, last time it happened during the first boss intro in MS2, another time in MS1 stage 3

It does sound a lot like the Bubble Bobble/Eternal Champions CD bug though

[slow grail]

didn't hear it in the first boss on ms2 (and you forget how bad that runs)

you're not using any rom hacks or anything, yeah?

[fickle hollow]

It did happen once with the MS2 turbo hack, but MS is just the standard rom

I'll do another MS run just in case later

I've finished it three or four times on MisterPi and the sound bug only happened once

[mystic geyser]

Question: I don’t see the HV adjustment in the latest unstable. Did the option go away for some reason?

[limber atlas]

Sorg rejected it

#1075091985007902812 message

[fickle hollow]

@slow grail I finally had some time to do some tests: audio distorsions happen more consistently in Nightmare in the Dark (sfx mostly) and Top Hunter (sfx degrades the longer the level goes on, then resets when a new level is loaded)

they seem to behave differently at each reset, Nightmare in the Dark sometimes only has distortion in the jump sfx, sometimes it affects fire sfx too; Top Hunter always has some degree of distortion starting from halfway through the level, but it's more or less severe at each reset

other games I tried (Spinmaster, Shock Troopers 2nd squad, Blue's Journey) seem unaffected even after 3-4 resets

[slow grail]

ok, I will check in a sec

and you have vga_mode=rgb yeah?

[fickle hollow]

let me check to be 101% sure 😄

[fickle hollow]

Yes

[slow grail]

cool, gimme 10 and I will see what's up

[fickle hollow]

thanks!

[slow grail]

I won't be able to fix it, but having another core affected by the bug might motivate sorg to look into it

[fickle hollow]

sure, I just want to be sure I'm not doing anything wrong before reporting a bug

and to be clear, these distortions are not as severe as the Bubble Bobble/Mega CD cores, at least not every time, just happened once while playing MS that the audio went completely bananas

[ocean phoenix]

Appreciate that attitude, keep on kicking ass

[fickle hollow]

I'm pretty new to this platform and I'm sure devs have better things to do 😄

[slow grail]

do you have it set to MVS or AES?

[fickle hollow]

I think I've tried both

[south cloud]

The sound quality of Nightmare in the Dark is also not one of the greatest on the original hardware.

[slow grail]

I'm having trouble reproducing in either. Let me try ypbpr

[fickle hollow]

now that you mention it, I do have decent analog audio recording equipment

[fickle hollow]

I can take my ADC out of storage and try to record the analog audio output, would that help?

(well I can't do it today :D)

[slow grail]

yeah, if you don't mind. no rush, and we may just be chasing ghosts here. I don't know if it's related to the 9.2 audio issue or not. but when someone says distortion and 9.2, my ears perk up

[fickle hollow]

Ok, will do that this week

thank you

[slow grail]

no no, thank you

it's like I think I hear it in top hunter but, you're right, it's not as pronounced as it has been in other cores

unless it's worse on your end, which is possible too

[fickle hollow]

I'm currently using headphones, and it seems to happen randomly

like, while playing MS, I was sure my speakers were dead

but distortion as severe as that just happened once

[fickle hollow]

@slow grail I managed to record the issue, though not with the semi-pro equipment 🙁

[slow grail]

perfect. I will look into this later today 🙂

[fickle hollow]

in nightmare in the dark, the jump sfx is always glitchy, on some resets it also affects the fire sfx

the top hunter recording came from a relatively distortion-free playthrough (of course that had to happen while I was recording)

[grand valley]

Is metal slug 2 supposed to slow down so much ?

[haughty veldt]

Yes. The game is infamous for its slow performance.

[abstract fractal]

No, it's suppose to slow down even more.

[haughty veldt]

Metal Slug X is basically them fixing Metal Slug 2.

[abstract fractal]

You can try the MS2 with speed up hack, I like 2 better than X.

[haughty veldt]

It's not exactly the same game, but it's like a director's cut.

[still gorge]

and is my favorite MS

[grand valley]

Which is it better for it to be set to?

[haughty veldt]

Just depends on what you're looking for. MVS is arcade settings, AES is the console version.

It's easier to credit feed a game in MVS mode, whereas a lot of the AES versions of games have limited credits/continues and more options. But you can also play the AES versions and use the cheats menu to give yourself stuff like unlimited continues anyway.

[crimson rivet]

Personally i set everything to AES mode. I like the consolized experience, you can pause all the games too, some games have extra modes, and as mentioned every game has cheats for unlimited credits anyways

[haughty veldt]

Same. It's what I do as well.

[crimson rivet]

I've tested every game, and the only game that has issues is Samurai Shodown V, but there's a cheat to run it in AES mode

I just do AES mode, USA for every game

[haughty veldt]

Then you have some games with CD versions that are even more console like. Neo Turf Masters being a great example with its user profile system that tracks all your stats.

[fading verge]

One thing to keep in mind is that aes versions are censored vs mvs, unless you prefer japanese language. So for uncensored English versions, mvs is sometimes the only option.

[south cloud]

I only use AES for Top Hunter, as the MVS version is stripped down by several stages.

[crimson rivet]

There are cheats in every one of these games to remove the censorship

It's all personal preference though. I just prefer the consolized experience

[fading verge]

Do you have to enable those cheats everytime you play? or the cheat settings are saved?

[crimson rivet]

Every time, but it's just a couple of button presses. You just need to open the Neo Geo Unibios menu and open the cheats section, so 3 technically

[opal gust]

Yesterday I was playing KOF ’96 on the MVS core, and I noticed that the right side of the screen was flickering when it reached the edge of the screen. Is this normal? Does it have anything to do with the 320 or 304p resolution? Thanks.

[haughty veldt]

If it's just flickering on the edge of the screen, it's very likely to be normal since that's something that occurs in a lot of retro games. But I can't confirm it myself since I don't have original Neo Geo hardware.

[limber atlas]

What kind of flickering?

There was a discussion about "flickering" some years ago in Art of Fighting 3 but it happened in real hardware as well

It is because of overscan garbage

CRT hides this.

[restive mulch]

96 is one on the few games where even at 304 you can still see some garbage at the screen edge when scrolling, it's accurate to real hardware though, not a problem.

[opal gust]

tks!

[brisk sparrow]

Weirdest thing happened a few days ago: when I was playing Alpha Mission 2 with the UniBIOS set to Arcade, some glitches appeared where it started me with only one life and it skipped the control selection screen. And then, a day later using the same ROM format, it somehow fixed itself? Just an odd happening, and I’ll bring up if it happens again.

[ocean phoenix]

Could be an extremely rare bug with the original game?

[brisk sparrow]

Possibly.

Excuse me? Neogeo games are perfect and bug free

[brisk sparrow]

On an unrelated note, what does everyone agree to be the “preferred” ROM format? I have two sets with DarkSoft and .neo versions, unsure if there are any differences.

[slow grail]

I use .neo

[ocean phoenix]

Uhhhhh, I dunno. I’ve used both and they’ve bin good.

That wasn’t intentional lol

[haughty veldt]

https://tenor.com/view/dumping-trash-daniel-labelle-frustrated-garbage-trash-gif-27186872

[inland drum]

Neo geo turbo cores no longer pinned? I had some installed but they didn’t give me the option to load cart games, only ngcd…?

[fickle hollow]

I think they are not well liked by devs, though I'm not sure why since people do overlook their physical boards

[ocean phoenix]

Because those cores break all games except for like Metal slug

[abstract fractal]

When people over clock a real NG does it behave the same way? If not, that's an indicator of the core not being the same right?

[slow grail]

Not necessarily

[lucid salmon]

If you had 20 Fiat Puntos and revved them to the max for an extended period of time, I doubt they'd all conk out at the same time. Doesn't mean any of them are less accurate to their schematics.

Yes, that is a very vague and probably rubbish analogy

[fickle hollow]

Yes, and TheJesusFish attempted to make an updated Turbo core supporting analog 9.2 boards, but I think it was too turbo and broke everything 😄

[fickle hollow]

doesn't stop locals from revving up fiat puntos

[slow grail]

Not everything. Metal Slug ran

[fickle hollow]

it was glorious 🤩

[inland drum]

That was my use case. Had a go at the ‘Metal slug 2 turbo’ romhack and it felt worse vs what I remembered of the turbo cores. Tried my installed turbo cores but no dice. Ok lemme get em from the pins here….nope not there. Guess i’d be able to find em on git. Or failing that maybe some troubleshooting and checking if bios files need to be added to make my installed turbo cores work.

[abstract fractal]

The analogy is fine, but I would say it's not a good comparison b/c if the MiSTer core breaks on every game except the MS series, every time, while real NGs break here and there based on age/construction from the factory etc, the core is probably not accurate. If everyones core broke at random spots on random games I would say the core is working like the real system.

[abstract fractal]

And if real NGs freeze on every game except MS series, then the core is behaivng properly!

[slow grail]

What happens if two real NGs behave differently? which one is behaving properly?

[lucid salmon]

You drop them both onto concrete and whichever one survives wins

Survival of the fittest

[fickle hollow]

There's a couple more games that work w/ overclock (like Shock Troopers 2), people actually install two different kind of overclocks for different games. The majority of the NG library glitches out tho

It's even detected by Unibios

To be clear, I trust the devs' judgement. I'd like if the NG core had two overclock speeds just like people do with real hardware, but if developers think it's stupid, they're probably right 😄

From what I'm reading, people who choose to overclock their HW put a switch to select 12/14/18mhz, with 18 only working with MS1-2

[abstract fractal]

Interesting

Sounds like something to try one day with one of mine

[uneven vector]

Metal Slug series runs at 30FPS for some reason?

[ocean phoenix]

I don’t even know how the increased CPU speed was achieved, could be wildly different than actually modding your hardware

Personally if there’s any discrepancy between hardware and the modified core, I would investigate the modified core first

[lucid salmon]

Metal Slug 2 wishes it ran at 30fps lol

[fickle hollow]

mind you, hardware mods still break most games, this is why people use a switch to go back to stock speeds. the threshold seems to be 14mhz, where a good number of games still work and benefit from it; 18mhz is used exclusively for MS1-2

[ocean phoenix]

Great to know! Thank you.

[slow grail]

Alright you sickos, I looked into this more. The turbo core didn't overclock the cpu to 14 or 18MHz - it overclocked it to 24, which would explain why it was so unstable.

So Claude and I got to thinking... We removed the 24Mhz option, and instead added overclocking to 14 or 18MHz. In this version of the core, you'll see a turbo menu option that has three modes

• Off (stock 12MHz)
• 14MHz (uh...14MHz)
• 18MHz (I'll let you guess)

Test it and see if you find it to be better.

[haughty veldt]

I am not a turbo sicko, but I salute you helping the sickos of the Neo Geo community. 🫡

[fickle hollow]

I'll test it later tomorrow, thanks!

I'm not part of the Neo Geo community, but I'm definitely a sicko

[wintry agate]

I don't think it leads to something useful in that state. The few games i tried had massive graphic glitches. Pulstar, Last Resort, Shock Troopers 2nd Squad, Blazing Star are unplayable.

[limber atlas]

The turbo core was a mistake

[fickle hollow]

Pulstar and Shock Troopers 2nd squad should be fully working at 14mhz on real hardware

[wintry agate]

Only in MAME the Turbo function works fine. But i guess it's a complete different approach.

[slow grail]

Yeah, this was more of a curiosity than anything else. After I saw that it wasn’t running at either of the “traditional” overlocks, I wanted to see if “properly” overclocking it worked better. I don’t know how games function on real overclocked hardware, so I needed more eyes on it before I deleted it

[inland drum]

Will try these out. Will also check in my ‘retro bubble’ to see if there are neo owners with this mod to compare behaviours. Thanks for the efforts, greatly appreciated!

[south cloud]

MS2 is better, not perfect and some heavy slowdowns remain.

Pulstar is heavily glitched with any of the OC options.

Same for ST, heavy glitches.

[bitter spire]

Need to test out Twinkle Star Sprites. That is another one prone to lag on stock hardware.

(Albeit kind of a necessary evil since that game gets chaotic fast)

[strange grove]

the dreamcast port even gives you the option to retain the original slowdown lol

[ocean phoenix]

Give it up Neo Geo sickos and embrace the slowdown!!!!

[inland drum]

https://tenor.com/view/yes-man-no-man-no-gif-7347715096894588969

[ocean phoenix]

damnit, well it was worth a shot

[slow grail]

This shit really only does work with metal slug

incredible

maybe I'll just change the menu option to "Metal Slug Mode: On/Off"

[abstract fractal]

LOL

so I was right about the core overclock being different than the real deal, but at the end of the day, it didn't matter, b/c it just doesn't work anyway. Awesome!

Thanks for your work regardless @slow grail !

[inland drum]

Just tried it, 18mhz felt a bit too fast (reminds me of the ms2 turbo rom hack)😰 but 14 is lovely!

[fickle hollow]

Ms2 turbo hack "fast"...? 🤯

In my experience it still lagged more than MS1 😄

[inland drum]

the enemy walk speed is off putting to me, the towers segment what i think it first real noticeable lag event indeed does play nice with the hack. Oh wel, i got vanilla, 14/18mhz and the hack to choose from. so will keep on experimenting and see where i end up. But so far 14mhz seems to be ' just right' for me.

[fickle hollow]

ok so, yeah unlike real hardware overclocking it breaks mostly everything (FF2 works with some glitches at the edge of the screen)

BUT, also unlike real hardware, it works perfectly fine with MS3!!!

since I'm so sick I should get a Jared Leto Joker tattoo, I tried it with MS2Turbo hack, also works fine except two very minor bugs (announcer clips seem late or rarely do not trigger at all, one garbled line in one boss)

[still gorge]

Turbo sure would be nice if it worked on more than one or two games lol

I suppose this is one of those things that's just easier with software emulation

[slow grail]

Claude take the wheel

[willow girder]

A new turbo core for one of my favorite consoles arcade systems. Thanks!

[still gorge]

What games have slowdown I'll try some now

[slow grail]

I don't think it fixes any of those. Most stuff has less graphical corruption

[still gorge]

Huh? What's the point of turbo then

[haughty veldt]

Metal Slug is the point!

[still gorge]

That already worked

[haughty veldt]

For the turbo sickos that is.

[slow grail]

I'll probably just rename the turbo option "metal slug mode" and call it a day.

set the right expectation

[still gorge]

Twinkle Star Sprites corrupts graphics

[slow grail]

yes, but less!

[still gorge]

No?

[slow grail]

used to be awful at 14mhz, now it's just bad

(you're welcome)

[ocean phoenix]

I hope you Neo geo sickos are happy!!!!!

[inland drum]

Damn it feel good to be a gangst…wait checks notes Neo Geo sicko!

[ocean phoenix]

I’m a little jealous ngl

[slow grail]

Ok, this is my final form. As you can see, this is definitely not a turbo core. It's for metal slug only

We will never speak of this to anyone. Not sorg, not kit, not robby. It is a monument to our collective sin, and we will keep it secret

[hushed onyx]

You can't escape judgement in the end

[willow girder]

TBF Neo Geo is a Metal Slug console with some bonus games.

[olive garnet]

That's the worst misspelling of Magical Drop III I've ever seen.

[haughty veldt]

Neo Turf Masters is da bestest Neo Geo game!

[dim gazelle]

Thought you guys might get a kick out of this. It's an MVS multi cart that uses FPGA

[strange grove]

i've considered going back to real neo geo hardware at some point, but the cost of the neoSD combined with terraonion's horrific customer support, lack of firmware updates and reliance on proprietary file formats has been enough to turn me away from it completely

the mister core is just too good anyway

[dim gazelle]

I gotta agree. My friend paid WAY too much. I ran Metal Slug X and was not impressed. But he already had that console conversion and he's got Bomberman and a couple other carts. I told him he should make a video comparing them. I have not tried to run Neo Geo on my Mister but if he goes through with the video, I'll donate my hardware to the comparison.

[strange grove]

more comparisons are always welcome. if i'm not mistaken, the neo geo core is one of the most accurate cores of the mister project, mostly thanks to furrtek's work on decapping and tracing the ICs from a real system

it's already amazing to have accurate neo geo emulation, especially when the cost of the original hardware is as prohibitively expensive as it is. support for uniBIOS and neo geo CD games just make the core that much sweeter

[dim gazelle]

From my understanding, there are a lot more custom chips inside the carts. The basic AES/MVS hardware is very minimal with lots of connections to send raw signals where the cart connects. That's why the system lasted so many years and why the carts are so expensive. The only thing that took it out was the fact that higher video resolutions started to become the standard. It's like the many chips you can find in SNES carts except instead of some carts only having 1 or 2 custom chips, all the carts have their own set of chips. To do it right, you would need to go through a bunch of them. Can't imagine it's easy.

[strange grove]

i think a lot of the chips found in various neo cartridges are either for decryption, bank switching or, most often, as simple glue logic (as in chips meant to replace/consolidate many smaller, discrete components). it's not like SNES carts that have entire coprocessors in them, often more powerful than the console they attach to

[tawdry plover]

The cheapo 161-1 multi cart is fine any anything not on it can be bought as a brand-new repro for pretty cheap

Like, repros are under $50usd iirc

[willow girder]

The other potential issues with real hardware is voltage droop. I have an older 5V AES and when running the TerraOnion cart certain games, usually the larger "Gigapower" games, can glitch out. The cart is so power hungry.

I use MiSTer 99.9% of the time.

The AES is just shelf candy basically.

[strange grove]

i've no idea where to find neo geo conversions under $50, and i don't really want to start a collection of bootleg carts anyway

the sad reality is that the only name in the game as far as neo geo flash carts goes is terraonion, and i'd really rather not give them more money, much less $700 for a product that's essentially abandonware now

[outer thicket]

Is there any reason to use a real console vs the mister core?

[strange grove]

genuinely no

[outer thicket]

So mainly just bragging rights

[strange grove]

pretty much. i do like playing on real hardware where i can, but the mister beats an original console + a flash cart in 9/10 cases, especially with neo geo

[willow girder]

There's BackBit and DarkSoft too but both of them seem to be OOS often and BackBit only does MVS.

For a little while there was a mod for those 161 in 1 carts where you could install the entire library in the cart. It was only on a certain version from a few years ago. Wish I had hit up one of the modders that was doing that work before they dried up. You couldn't add games, at least not easily without desoldering and programming the chips, but it would have been neat as a time capsule of all the official games on a less power hungry cart.

[strange grove]

darksoft doesn't plan to make his multi cart carts again iirc, and the backbit is MVS-only, which is fine, but i'd prefer to play on the AES system

the modified 161-in-1 carts were good, but i believe it took two donor carts just to make a single modded one, and even then, a few titles weren't compatible with it. only the prototype version of garou worked, and only bootleg versions of SVC chaos worked

[willow girder]

Ahh I wasn't aware of that compatability issue. Thanks.

[strange grove]

it's a shame as they're a great option otherwise

[willow girder]

I just happened to find the git for that project. A little more involved than I'd like to get. Especially with drag and drop options and MiSTer of course.

[strange grove]

yeah, they were pricey and difficult to make. still less than the other flash carts, but not by much

[tawdry plover]

Ah, less of an issue with the MVS as you can just adjust the voltage directly.

[tawdry plover]

Physical media being comically large, plus box art if you invest in it, are the main benefits

If you don’t already own a supergun or arcade cabinet, you’d be spending a few bucks even just getting set up with an MVS and 161-1 cart

[strange grove]

the neoSD struggles with a lot of MVS boards too, last i checked. i never got it to work properly with one of my older 1-slot systems

[tawdry plover]

That’s too bad. Finicky arcade hardware is the worst.

My only original cart is KoF 98, most MVS games are out of my price range now 😩

[strange grove]

it's a shame too, since they used to be the "cheap" option for collecting neo geo games

[tawdry plover]

Yup, still not as crazy as AES but Garou would probably run you $350+

No thanks, I’ll just enjoy my repro lol

[strange grove]

that's more than enough to buy a mister too 🙂

[tawdry plover]

Right!

[tawdry plover]

This is actually my MVS and mister running side by side 🤪

[strange grove]

very pretty setup. JVC land

[tawdry plover]

One more behind me in the Wood City

Sadly, no tate games available for the MVS so it’ll never be inside that cab

[strange grove]

always found the lack of tate games on the neo weird. even strikers 1945 plus, despite being tate originally, was redone to run in yoko

[tawdry plover]

Yes

“We should decimate this painstakingly drawn artwork”

Also wtf is with 2 lives by default in that game

High score runs are murder

[strange grove]

right 😭

very odd version of the game

[restive mulch]

Multislot would be awkward for arcade operators if games were a mixture of yoko and tate I guess. Potentially home versions in mind as well.

[strange grove]

that's a good point

[willow girder]

I love these cabs you make and with repurposed TVs. Awesome to see.

[placid granite]

i too have one of those

[placid granite]

Just get a Backbit Cartridge then.

[placid granite]

you haven't ever run Neo Geo on your MiSTer? But that's on of 3 main reasons to have a Mister.

[placid granite]

the prices went skyrocket. are you sure you only paid 50$?

[ocean phoenix]

Real Neo Geo fans do AES

[strange grove]

i prefer the AES system. the backbit is almost as much as a neoSD pro now, anyway

[placid granite]

with deep pockets. at least i can buy a lot of MVS carts 😉 try buying all Metal Slugs for AES 🙂

[placid granite]

that's true for the price but still better imo. the concept of flashing 4 games is laborious.

[strange grove]

true. i appreciate that the backbit behaves a little more like a traditional flash cart in regards to game loading

[placid granite]

why do you prefer the AES? any specific advantage or just because it's the original console?

if you like loading times you can go with one of these 😉

[strange grove]

AES experience is a little more polished, like having a difficulty select in-game rather than adjusting it via the service menu. being given limited credits encourages me to play better as well

one thing i like about the neoSD is that it allows you to run games in AES or MVS modes, regardless of system type. i'm unsure if the backbit has the same feature

[strange grove]

i do love the neo geo CD, especially for the games that got exclusive content, but i think SNK stopped releasing games for it after 1999, so that means no garou, metal slug 5, SVC chaos, etc.

[tawdry plover]

The 161-1 is still about $120CAD but single game repros are around $70CAD. Main seller of the repros on Ali has their store offline rn for lunar new year

[strange grove]

wasn't there some concern for a while over the voltages in the banana cart? i don't recall the specifics, or if it was ever fixed

[tawdry plover]

Dunno

I sold my banana

These use recently manufactured PCBs and new shells, and seem really good quality

[strange grove]

interesting. a vortex cart plus the repro carts would be a good combo, but i'd prefer something with ROM loading

[placid granite]

that is irrelevant when you use a unibios. i can set my OMEGA to act like an AES.

[placid granite]

again, unrelevant with unibios

[strange grove]

ah, i've never installed a unibios on any of my neo systems. good to know it has that feature

[placid granite]

they stopped because those werent liable as CD version

[tawdry plover]

TBH the cost of the vortex cart exceeds the cost of the single games I’d like to own lol

[placid granite]

why buying repros in the first place?

[tawdry plover]

Originals are more expensive and in worse condition

[placid granite]

just buy a flashcart

[strange grove]

that's also understandable. last blade 2 is a good example of that; great port but horrendous load times

[tawdry plover]

No

[placid granite]

that is basically the first thing to do 🙂

[strange grove]

still, i like that the feature is built-in to the neoSD

[tawdry plover]

Vortex cart has instant load times I think? Do any of the other multi carts offer that?

[placid granite]

sure. but with the unibios you can use it systemwide with all carts

[placid granite]

the only one is the backbit with 12s max per game. smaller games go even faster.

[tawdry plover]

I might rebuy a 161-1 but I might honestly just buy a couple more repros instead

Blazing Star and Magical Drop 3 maybe

[tawdry plover]

Changing the region to enable or disable the FBI drug warning is a fun feature of the unibios too

I have an FZ with the socketed bios so it was just a chip swap for me, no soldering

[ocean phoenix]

If it’s not AES it’s not real

[placid granite]

yes, most AES also have socketet bios

[placid granite]

well if you want logic, actually the MVS system came before the AES. That means the MVS is the original Neo Geo and the AES is just a consolized port.

[tawdry plover]

Your mistake was assuming Roppi wanted logic

[ocean phoenix]

lol

[tawdry plover]

Love u bro

[placid granite]

collecting MVS carts is more feasable 😉

[placid granite]

why don't you like the boxes?

[tawdry plover]

Poor construction, the material is like a weird vinyl and the inserts that hold the carts are ultra fragile

[placid granite]

and those are also from the same i ordered?

[tawdry plover]

No I got mine from — let me find the link

[placid granite]

do yours have an extra insert for AES or MVS carts?

[placid granite]

i know that store. didn't know he had boxes also

[tawdry plover]

It’s like a wide open box that has a super thin plastic shell, similar to what they package Easter chocolate bunnies in

Idk if he still sells the boxes. On CNY break now

[placid granite]

uh yeah that sucks

[tawdry plover]

Yeah a few arrived with the plastic inserts already damaged

Would not rebuy. Yours look more robust

This is what the repro carts look like under the hood

[placid granite]

absolutely, i can vouch for these

[placid granite]

i know these. i have one, the xenocrisis 😉

[tawdry plover]

Haha, same. I later felt bad so I bought the rom from Bitmap Bureau 🤪

[abstract fractal]

If that's yours you know you can flip the boards around so the label faces the correct way.

[dim gazelle]

it's not mine. It belongs to my friend. He's something of a bomberman fanatic. He made this video:
https://www.youtube.com/watch?v=1tCnVuPmHwI

[tawdry plover]

Risky move 🙂

[abstract fractal]

What do you mean? It was designed so that you can have the label face either direction because so many mother boards are different.

[tawdry plover]

I’d just be so worried about accidentally putting it in backwards then due to muscle memory 😅

I have a front-loader MVS so I have to try really hard to mess up inserting a cart

[abstract fractal]

Ah ok

yeah, I think there is an arrow you alwasy want to line up with NG carts

but yeah, I guess if you're use to doing it one way, it would be risky!

lol

[tawdry plover]

Wouldn’t feel comfortable loaning them to friends 😅

[abstract fractal]

I would be worried about lending them to your friends with the label backwards most people plug it in automatically with the label to the front, no matter what the arrow says

[tawdry plover]

Valid, the PGM’s cartridges are actually keyed so they only fit in one way, too bad they didn’t do that for the MVS

[placid granite]

Did you already plugged one the wrong way in? Did it damage anything?

[tawdry plover]

No accidents here 🙂 it would probably fry the cart

[thorn dove]

Your friend did that video?? I'm actually halfway through it and I'm gonna say that I love his dedication lol

Holding out for khashoggi myself

[strange grove]

i haven't had much faith in SNK for years now, but the recent city of the wolves trailer using AI is what really solidified them as a soulless husk of the powerhouse they once were

[tawdry plover]

Just means you don’t need to feel bad for not paying for their games

I’d take MOTW over COTW any day

[haughty veldt]

It's been frustrating for sure. City of the Wolves is a genuinely fantastic game. But holy hell they f'd up the marketing for it and made extremely poor decisions regarding a certain guest character that I shall not name. You could argue that the game itself is the best current fighting game on the market, the gameplay is really that good, but it's a tough pill to swallow knowing all the issues surrounding its release.

[ocean phoenix]

I passed on the game because of specifically that

Not even joking, I found it that weird

[slow grail]

There are too many systems in that game

[lucid salmon]

Systems are a bit of a put off for me in general. It was so refreshing going back to Street Fighter II on SNES and just having the bare basic stuff.

[woeful copper]

Ha whuuuut? This is bizarro

Personally I never liked soccer, and this doesn't change matters 😆

(True story, I animated Ronaldo for a Nike film/commerical many moons ago)

[ocean phoenix]

It’s funny because there’s no controversy, it’s universally disliked by everyone and the game suffered poor sales as a direct result. The CEO even got fired for it.

Shit decision tanked the games sales. I hope they learn from it.

[restive mulch]

As if the CEO made the decision to include those characters, that's 100% because of Saudi money.

[ocean phoenix]

Yup!

[restive mulch]

Shame as up until those characters were announced I was really hyped for the game, such a waste.

[fickle hollow]

[dim gazelle]

My bomberman buddy is interested in checking out my Mister. I found a compatible romset but it only works when the files are in a ZIP and not when extracted into a folder. Is that expected behavior?

also, it appears unibios is switching between AES / MVS irrespective of the menu setting.

[south cloud]

That's normal.
The games must be either in ZIP files or in .neo format (NeoSD compatible).

For Unibios, you can select the Arcade or Console mode at startup with keeping the A+B+C combo pressed when booting the game.
You can choose the Mode and the region for the game.
It will be saved on the NVRAM after that.

That setting is set up for each game, and not globally.
The OSD option is valid for the official BIOS only.

[dim gazelle]

ok. thanks. it looks like the update_all script pulled the 4.0 version of unibios. I was able to load 3.3 without issue (his console kit has 3.3 and I want to try and duplicate his setup as much as I can) He had to do something funky to load the roms to his cart. I wonder if that was mame -> NeoSD

[tawdry plover]

.neo files seem to work well. I had to try a few rom sets before I found one that worked with mister

[limber atlas]

It is recommended to set the system mode to Arcade in mister osd and switch between console/arcade in the unibios

[slow grail]

AES people are monsters

Top Hunter is better on AES.

[unreal swallow]

call me crazy, but I kind of like the fact that AES games are adjusted for “console/home mode” play…I’m about to try popping a unibios in my Big Red and a big reason for me is to have the ability to switch between AES/MVS modes

well, that and hopefully the ability to use the “pick n mix” mode with a multicart

[wary bronze]

Yeah, Magician Lord has cutscenes and stuff. There's a few titles that have extra bits.

[strange grove]

ah, neat

[ocean phoenix]

I have all my Neo Geo games as AES and MVS because I am the ultimate life form

[uneven vector]

You're Shadow the Hedgehog?

[placid granite]

i just switch my OMEGA to AES with the unibios then. no probs.

[tawdry plover]

Bubububut the bios determines which version you play, not the cart

[placid granite]

not all AES or MVS carts have the same content on them. ex Magician Lord.

[tawdry plover]

Now that’s interesting

So if I grab an MVS Magician Lord and put my bios in AES mode, what do I get

[fading verge]

Magician lord Aes and MVS are quite different. Besides cutscenes, Aes you get checkpoint based respawns, with MVS you respawn immediately. AES gives you 3 points in the lifebar. MVS gets you 2. I still prefer the Aes version as that's what I played as a kid, so I use that in MVS mode for unlimited credits. Never tried it but If you do the reverse, I assume you would get the MVS features and limited credits.

[tawdry plover]

Interesting. Do any aes games have a pause feature? That’s the one thing I wish I could change about Neo Turf Masters

[ocean phoenix]

Yah you’re right, I use MGLs to launch the games in aes or mvs mode

[tawdry plover]

I should do that

[fading verge]

I think with AES mode you get pause in all games. That is the main advantage.

[tawdry plover]

No pause with my MVS cart in AES mode sadly, at least on Neo Turf Masters

[fading verge]

Odd, just tested on mister and it does allow pause in neo turf master with aes mode. I just had to remember which button I mapped select (pause) to. Kept pressing the coin button to pause till I realized my mistake.

[ocean phoenix]

More like aessssss mode

[tawdry plover]

Maybe I should try again

Ohhhhhhhhhhh pause is the coin button

Lmao

Okay, only playing this in aes mode from now on. 18 holes is too much without a break

[fading verge]

It is? I had them mapped to different buttons. No idea I could only have one button doing both.

[tawdry plover]

Sorry I mean on my actual MVS

Coin pin on the jamma edge triggers pause in aes mode

I actually don’t know if you can map coin and pause to the same button via the mister OSD but try mapping just coin and see if it pauses aes

[fading verge]

Seems on the core they have to be mapped individually.

[tawdry plover]

Sure, I mean skip mapping pause

Then use whatever you mapped as coin, see if it acts as pause in aes mode

Would have been a cool arcade feature, 25 cents to pause a game, 25 cents to unpause

[fading verge]

Yeah, tried that but no use. Worth a try though.

[tawdry plover]

Strange! And you’re using unibios?

[fading verge]

MMM, no, original bios.

[tawdry plover]

Aha

Set to unibios and arcade mode in OSD

Then when you boot, hold ABC to access the unibios menu and set it to aes

(lol)

That should hopefully do it

[fading verge]

Good call, will have a look later.

[tawdry plover]

Might not be practical unless that unibios setting can be applied across all games without manually doing it

[fading verge]

Does unibios allow that? set a default for all games? I am trying to find a way to quickly change aes regions but don't want to do it individually.

[tawdry plover]

On a real MVS I think it should save the setting between power cycles? I’m not sure I have a battery in mine atm

Ok! It works on mister

These settings will let you pause with the coin button

According to unibios page this doesn’t work for all games

[fading verge]

Oh well. No big loss, I can always use an extra button for pause. As NeoGeo only uses 4 buttons.

[fading verge]

Would it be hard to implement a region selection when using original bios? I think that would be a way to quickly change all games.

[tawdry plover]

Hmm, good q. I suppose there’s an original bios for each of the three regions?

Cursory search doesn’t turn up any solid info

[fluid idol]

Back in the pre universe bios you had to indeed change to another regions bios.

[ivory grove]

Most if not all games have a cheat to allow infinite credits in AES mode. iirc ABC Start opens the in game menu that have a cheats menu.

[fading verge]

I think you can manually swap between different region MVS and AES bios files?. But I don't think it would be too difficult for the core to select different versions of bios based on a region toggle. I am not a developer though so maybe it is too much work but I think it would be a major usability improvement.

[wary bronze]

Well yeah, but in AES mode it turns all the blood in Neo Turf Masters into 'sweat' || ||

[drowsy kelp]

Anyone have any luck starting a game of the Karnov port on the Neo Geo CD? I could swear that it used to work, but now pressing select won't "insert a coin" so the game can start. It works perfectly fine on OG hardware and the retroarch NeoCD core.

[trim shard]

Is there any reason the Neo Geo core would take about 8 minutes to fully boot up to the menu ? Everything is fine after that.

[haughty veldt]

None that I can think of. Outside of maybe whatever storage you have it in.

[trim shard]

All other cores load instantly 🤔

[south cloud]

Do you use games in .neo format or zip game files ?

[trim shard]

ziped .neo files

[fading verge]

Tried manually deleting the core and bios and let update-all redownload?

[haughty veldt]

And maybe the config as well?

[slow grail]

unzip the .neo files and run it direct

[south cloud]

Ah, that's why!

Yeah unzip them, it should be much more faster.
EDIT : that was the core which had some troubles, not game loading.

[haughty veldt]

Oh yeah, never zip roms in my experience.

[trim shard]

I didn't had issues with zipped roms for other cores, it helps keeping things tidy when I've multiple hacks for one game

[haughty veldt]

If they're already in .neo format, no need to zip them.

[haughty veldt]

Even in this case, I'd just recommend using folders/directories for rom collections.

[south cloud]

.neo files are already compressed to some kind by nature.

[trim shard]

having ziped files would slow down the core boot sequence ?

[haughty veldt]

So it's the core OSD booting up that is slow, and not loading games?

[trim shard]

Yeah its the core booting up

It takes like 8min or so

before I can access the menu to load roms

[haughty veldt]

That's a first for me, so not sure the cause then. It should only take a moment.

[trim shard]

Something to do with the config maybe ?

[haughty veldt]

Might want to delete the bios and run update all again.

But yeah, really just delete the core, the bios, and the config and do update all to start fresh.

[trim shard]

That's MiSTer.ini right ?

[haughty veldt]

No, there's a config folder.

Just delete the NEOGEO files in that folder.

Back them up first though just in case.

[slow grail]

what stack do you have, Hydra?

[trim shard]

Multisystem2

[slow grail]

so when you select the core itself, it takes 8 minutes to get to a menu to load a game?

are game loads slow at that point too?

or does it act like a normal core

[trim shard]

It acts normally, just takes a long time to load. Initially I thought it didn't work then I got called for something for 10min and saw that the menu had appeared when I got back. I eventually ran a chrono to see how long it takes

[trim shard]

That did it

It loads instantly now

[slow grail]

nice. really weird

[south cloud]

Okay, we thought earlier that was the game loading which had trouble, not the whole core initialization.

[trim shard]

yeah everything was working properly once it had loaded I played a few different games for a few hours without any issues

[haughty veldt]

Nice! Often times replacing the config file fixes weird issues that crop up. No clue what the cause could have been though.

[slow grail]

8 minutes is excessive

[austere nymph]

To add to romset.xml

"<romset name="turfmastscot" altname="Neo Turf Masters (Hack Scotland Course from CD)" altnamej="Big Tournament Golf (Hack Scotland Course from CD)" publisher="Nazca - dericmiller" year="2026"/>"

[austere nymph]

Fatal Fury 3 (darksoft) is showing black screen for me. Have you the same behavior ?

[south cloud]

UniBIOS ?

[austere nymph]

japanese bios

stock one

[south cloud]

No issue for me.

[austere nymph]

with unibios it works

[south cloud]

Arcade (MVS), JPN, Original BIOS, Fatal Fury 3 (fatfury3).neo

[austere nymph]

Darksoft it shows black screen Arcade (MVS), JPN, Orignial BIOS from clean start

interresting

If i choose unibios it works and if I choose original after without restart the core it works also

[restive mulch]

FF3 sometimes wouldn't boot for me with a .neo file too. MVS, orignal bios.

[limber atlas]

darksoft roms are a bit tricky

https://github.com/MiSTer-devel/NeoGeo_MiSTer/issues/213

[austere nymph]

I see this issue I will add it my case maybe it could help to have another case

[tawdry plover]

I am too stupid to figure out how to do the Neo Turf Masters Scotland rom hack 😔

[tawdry plover]

Did all the ips patches but can’t create a .neo file because the tool reports a CRC check failure

[strange grove]

i am extremely out of my depth to be making sweeping criticisms like this, but i feel like every file format we have for neo geo software is flawed in some way

[tawdry plover]

Just patched the darksoft roms and added the above entry to the xml file and it worked

[slow grail]

My latest sin: https://github.com/TheJesusFish/NeoGeo-Arcade

[tawdry plover]

King

[slow grail]

i haven't tested all of them, so please let me know if you catch any mistakes

like it looks fatal fury 3 isn't loading

[tawdry plover]

Someone was having problems with that game earlier

[slow grail]

ahh I thought that was samsho, but it's the issue that is for samsho

It will boot if the core is set to console, but not arcade

Is Europe the preferred region? or should it be japan? USA?

[slow grail]

Nevermind, looks like that setting isn't exposed to MiSTer Main

[tawdry plover]

For the record Europe is popular because it’s English without the fbi warning screen

I believe that’s also the unibios default — Europe, Arcade

[slow grail]

europe console I think is the default for the neogeo.cfg, but I could be wrong. Either way, these all set europe arcade (if you use the bespoke config set)

[tawdry plover]

Found this info drop on the forum. I was having trouble getting into the unibios menu

[slow grail]

yeah I saw that. I didn't want to mess with the setting there, but I could

also, it looks like columns is not an arcade game

[tawdry plover]

There are a few recent Sega ports to the Neo Geo

[slow grail]

it loads with arcade set, but it doesn't need coins it seems

[tawdry plover]

Sure I’ve seen Shinobi MVS carts on Ali

[slow grail]

yeah, this is good, I need to pull out the stuff that shouldn't be there

[tawdry plover]

Kind of odd that the Neo Geo didn’t have any input test options, hey

Buttons wired up wrong? Load up a fighting game and figure it out

[limber atlas]

This is fine. Neo Geo was one of the reasons why MGL was created

It would be nice, if you have time or motivation, to adjust aspect ration per game

https://drive.google.com/file/d/1ieshu26TAHAZqSRXpCWYBntr-eIHSJBK/view?usp=drivesdk

Made by firebrandx

[slow grail]

I have the motivation. I just need to gain the understanding

[limber atlas]

I’m out let me come back home and I’ll explain

[tawdry plover]

Ohh does this have to do with games putting important info in the overscan area

[slow grail]

I see the menu option. I will make this happen

[slow grail]

Ok, updated the release. The Config file now has the proper crop and I removed the games that were non arcade. python script now asks the preferred crop for any files you use it on. https://github.com/TheJesusFish/NeoGeo-Arcade/releases/tag/202604

[upper garden]

i found this to create a .neo file. no crc checks, just does the needful
https://github.com/city41/neosdconv

[topaz holly]

Quick (maybe dumb) question: Can I rename the ‘_Arcade’ folder to ‘_Neo Geo Arcade’? I want to make Neo Geo games easier to access. Do I need to change anything else anywhere?

[slow grail]

yep, that will work just fine

the config files only care about the set name (which is baked into the MGL) so the folder can be named whatever

but the rom folders have to be set up like HTGDB

[bitter plank]

Nice work!

[slow grail]

I should see if I can have Claude make a script to roll your own

[topaz holly]

Do you mean HTGDB folders? Where should I place them—games/mame? Should the ROMs be in Darksoft format or .neo?

[slow grail]

games/neogeo

.neo is what they are expecting

[quaint magnet]

not the slop!

[slow grail]

https://tenor.com/eFCFaAosjC6.gif

[topaz holly]

I think I’m doing something wrong—when I try to load any game, all I get is this screen

One more thing: where should I put this folder? media/fat?

[slow grail]

oh that folder shouldn’t be there. Thats a byproduct of zipping it on mac. you can delete it

[wintry agate]

There is also a nice Windows GUI tool, which makes it much easier.

https://bidouillouzzz.blogspot.com/2025/02/neobuilder-homebrew-v106-v2.html

[tawdry plover]

I tried that one but could not get it to work because it threw a CRC error

[wintry agate]

The GUI version? Works fine on my Windows 10.

[tawdry plover]

Yeah, I could get it to process the normal rom but not the patched one

[wintry agate]

Probably not designed for that

[tawdry plover]

Yes, that’s what I figured 🙂

The previous tool was recommended because it doesn’t do CRC checks

[upper garden]

i didn't have luck loading the mame rom on mister. had to pack it into a .neo or use patched darksoft

[topaz holly]

I have both but couldn´t make it work

[slow grail]

Ok, I think this is a better solution. This is a script that you drop into your /games/neogeo folder and run with python3 neogeo_arcade.py

It will

• go through your neogeo directory (and sub directory) and detect your rom files
• if the file exists in the mame db in the script, and it is an arcade game, it will
  • create an MGL file that matches your directory structure
  • a matching config file with the proper crop information and set the arcade flag
• if the file is in the DB and not an arcade game, it will ask you if you want to convert it
• if the file is not in the DB, it will ask if you want to do it manually where it will ask you
  • Game Name
  • Setname
  • Crop Info (320/304/none)
  • Whether or not it's a clone or a parent and, if it's a clone, the name of the parent
• If any games have duplicated set names, it will ask you set a new setname (and which one is the parent)

ive tested it a couple of times, and it's worked as expected. If I can get some other eyes on it, I will add it to my github and remove the raw files

[topaz holly]

@slow grail Can this script search for games on my external HDD as well?

[slow grail]

just drop it in the folder the roms are in and it will do the rest

it will create a folder called NeoGeo MGLs with an _Arcade folder and a config folder. once the script is done, you can copy the two folders to /media/fat to merge them with your existing folders

[fickle hollow]

can I put MGLs in a subfolder? and could it be possible to select the Japanese BIOS for those few games that are otherwise censored?

[topaz holly]

Thanks!

[slow grail]

Yes, you can put the mgls in a sub folder, but no, I don’t think there is a way to swap to Japan since the unibios option isn’t exposed in the OSD I don’t think

[quaint cypress]

I dropped it in my games folder, and all it does is pop up briefly and disappear. I just reinstalled Python. Anything else I should look out for?

[quaint cypress]

Do my NeoGeo roms need to be unzipped?

[wintry agate]

Oh my. And it's so much easier! (Yes, i know it can technically do more than the GUI tool). 🤣

[slow grail]

yes, sorry, I should have mentioned that

[quaint cypress]

word, all my NEOGEO roms are zipped, so that's probably my issue. I'll extract them and try again.

do NEOGEO roms need to stay zipped to run or can they stay unzipped?

[slow grail]

oh, hmm, you're talking about zipped roms (not a zip with all your roms in it). I dunno if the script can do that - might just be .neo and .rom. But let me look

[quaint cypress]

I unzipped them and the script finally ran, but it didn't generate anything in the MGL folder.

I'm downloading a new rom set, so I'll try that.

My roms are in the wrong format, so that explains the trouble I'm having

[slow grail]

im sorry, I need to add compatability for roms and zips

[quaint cypress]

I'm also getting this when loading roms from the Arcade list. Roms are now in .neo format.

[slow grail]

can you paste one of the mgl files here?

[slow grail]

is it in /media/fat/games/Neogeo/MVS/Garou - Mark of the Wolves (garou).neo

[quaint cypress]

yes

[topaz holly]

The script worked fine for me and created the MGLs, but when I try to run the games, I get this screen:

[tawdry plover]

That’s one of the bios screens, are your dip settings OFF in the OSD for this core?

I haven’t tried the script yet but I can give it a go this evening

[slow grail]

Has the script worked for anyone besides me?

[topaz holly]

Not sure if it helps, but here are the MGLs the script created. I also renamed the ‘_Arcade’ folder to ‘_Neo Geo Arcade’

By the way, the script is great—very intuitive, fast, and easy to use.

[ocean phoenix]

Does that create an arcade core setname for all arcade games or does it do a setname per game?

[slow grail]

Per game

[ocean phoenix]

Oh ok

[slow grail]

Using mame set names

[ocean phoenix]

Toya, will you marry me?

[slow grail]

It’s what they crave

[ocean phoenix]

They like per game configuration

[tawdry plover]

Should this be pinned

[south cloud]

Several people have asked me on that issue too in a recent past.

[limber atlas]

Yes!

[limber atlas]

I asked Sorg about this in the past, he said no!

[tawdry plover]

Sorry, what did he say no to? Setting Joystick-only as the default input type?

[limber atlas]

#1075091985007902812 message

[tawdry plover]

Ohh

I couldn’t name a spinner game with a gun to my head

I agree that having the unibios menu working by default is better than having the spinner working by default

[ocean phoenix]

Where are we having our honeymoon?

[slow grail]

It also follows other cores, yeah? You have to enable the spinner in the OSD

Also if more people can get eyes on that script and see if it works for them. I have tested it on 4 misters, one working completely off the SD card and it’s been fine. One thing I haven’t done is try other sets aside ring htgdb, but those other sets are a pain because they dont have the set name in the title

[limber atlas]

Amalfi Coast!

It is better if it set to joystick only.

[ocean phoenix]

lol thanks for being a good sport. Sometimes I don’t know if my jokes go too far or are terrible lol.

[limber atlas]

Should be an easy PR.

[limber atlas]

Haha, it is all cool 🙂

[slow grail]

yeah, agreed. I will update the script to generate configs with that already set

[quaint cypress]

At least for me, my roms load fine from within the core. If I try to access them through the Arcade menu after running the script, I get the Cross Hatch Test screen.

[slow grail]

I wonder if the core can be updated to expose the region settings

[tawdry plover]

Does the unibios region persist between power cycles on a real MVS? I don’t think mine has a battery

[slow grail]

it doesn't in the core. but it might if it's a setting in the OSD

[unreal swallow]

I actually just installed a unibios in my Big Red and it does

[tawdry plover]

Nice. I gotta get a battery

Have you tried the pick n mix feature yet?

[unreal swallow]

I actually haven’t because I got a second cart (League Bowling) and the Unibios page says it recommends not using Pick-n-mix if you have more than one cart installed…maybe it would work fine idk, but I haven’t tried. I might take that cart out soon and try it

it doesn’t really explain why it’s not recommended, though

oh actually, I think one of the reasons might be that I won’t be able to use the Select Game button to switch slots then maybe?

right now I can select a game from the 161-in-1 and then I can use the Select Game button to cycle between that game and League Bowling

[tawdry plover]

Ahh

Yeah unibios does have some weird gotchas

How’s league bowling? I ordered puzzle bobble today on a whim

[tawdry plover]

Script worked great for me, suggest having an option at the end to automatically copy over the generated files to the _Arcade folder

[slow grail]

I thought about that but I was too tired to think about to do that since the script doesn't really know where it lives

[tawdry plover]

Relative path for the source and absolute path for the destination?

Oh wait hmm

Would that not work if you ran the script from a different path maybe

[slow grail]

So like lets say I am running the script from a copy of the neo geo folder in c:\temp. It would have no idea where the arcade folder is

especially whether it's on an SD card/NAS/USB drive

[tawdry plover]

Right

[slow grail]

the MGLs all load ok for you?

[tawdry plover]

Yup, tried a half dozen without any issue

[slow grail]

thanks duder

[unreal swallow]

Loooove League Bowling! My buddy and I discovered it on MiSTer several weeks back and then when I got the cab working I realized the multicart doesn’t have it . Ordered a repro from Aliexpress

[tawdry plover]

Those repros are really good quality

[strange grove]

affordable neo geo flash cart never

[unreal swallow]

yeah…I am really leaning towards biting the bullet and getting the Neo SD Pro or the Backbit

the multicart doesn’t have Twinkle Star Sprites or Windjammmers either

[strange grove]

i'd probably sooner buy the backbit just because terraonion is 🤢 but the price of either is not an easy price to swallow

frankly i don't understand why they're so expensive. i doubt it costs $500+ to make one of these, so i can only assume it's neo geo tax

[unreal swallow]

right yeah

[tawdry plover]

I mean, ostensibly the creators would like to be reimbursed for their r&d time

Nobody’s selling niche, bespoke arcade hardware at cost

If they’re $500+, consider rounding out your 161-1 with a few single repro carts. They’re only like $45usd

[unreal swallow]

where do you find them for $45? Seems like everything I can find on Aliexpress is like $75-80

[ocean phoenix]

maybe cause they jack prices up on your since you’re in the US

[unreal swallow]

it does feel that by the time I buy a few more repros, I might as well just spend a bit more and get a cart that can do everything. I’d also like to be able to add the ports that have been coming out (Golden Axe, Shinobi)

oh yeah and Double Dragon One

[ocean phoenix]

Genuine question. Since NEO GEO is so accurate on MiSTer, why get a fish cart?

[unreal swallow]

well yeah that’s the other thing…I am also mulling over just getting a MiSTercade

which might just be the play since I could get the whole kit from Porkchop for about the same price as a flashcart anyways

[ocean phoenix]

Would a flash cart work on an arcade unit?

[unreal swallow]

yeah, neo sd pro or backbit have carts that are meant for the MVS arcade hardware

or there are these darksoft carts or the hacked vortex carts, but those are a bit harder to come by

[ocean phoenix]

that’s pretty cool

if I owned a Neo geo arcade machine, I would get the flash cart myself

There’s an incredible value in having it just function for what it was built for

[unreal swallow]

yeah that’s the thing too…I have REAL hardware right?

[ocean phoenix]

In a mostly above board way

[ocean phoenix]

Yeah, I’m with you then. Arcade cabs feel special to me in terms of keeping it authentic

Not that you need my opinion lol

[unreal swallow]

(I also got the cab for free, so the cost really isn’t that crazy )

[unreal swallow]

I appreciate it because you’re validating my brainworms about it 😅

keeping it stock and original is pretty cool

[slow grail]

Is there a list of the censored titles somewhere?

[tawdry plover]

Could be a tariff thing. I’ve bought a few from different vendors, these guys are cool: https://m.aliexpress.com/store/2676506482

Hmm does that link not work

Kuqi - Vintage Arcade Store

[tawdry plover]

I like collecting Neo Geo carts because they’re comically large personally

I actually sold my flash cart to encourage myself to buy more single game carts

[unreal swallow]

ah yeah I think maybe I came across them. Of course none of the places that had $50 -60 carts had League Bowling on their list

[tawdry plover]

Shoot em a message, they’re pretty accommodating. They’re making me a puzzle bobble to order

[strange grove]

how do the clone carts handle the special hardware for the later games? some bigger carts have bankswitching stuff in them

[unreal swallow]

hmm no idea

[tawdry plover]

They’re not clones of the original cart PCBs, totally new design

I can’t find photos, I’ll take some when I get home if I remember

[strange grove]

thank you, interested to see them!

[tawdry plover]

I’m sure someone smarter than me could figure out how to change the game on them

[full raven]

I don't know how accurate is MiSTer NEOGEO, but I see it without differences with real system

I have the real system and I did some testings ... it's perfect for me

[unreal swallow]

yeah it’s been a back and forth battle in my mind…flashcart or MiSTercade

[strange grove]

felt that. love my mister to death but there's just Something about real hardware

[unreal swallow]

I do like the idea of playing non-Neo Geo stuff on the cab too, though

but also, I would eventually like to get another cab one day

[tawdry plover]

(Chanting) tate cab

[unreal swallow]

haha well, that’s where it’d be nice to get a Vewlix/Chewlix

[tawdry plover]

I priced out the unico candy cabs yesterday and between shipping, exchange and sales tax it would be $3,800cad to the door. No thanks

[unreal swallow]

hmm yeah seems steep for something that’s not even original

[tawdry plover]

Good for them for making em, moreso with jamma connections, but $900cad for shipping seems a bit much

Exchange rate sucks now too. They’re probably a better deal if you live in the USA

[full raven]

the real machine is magic

it has this BOOM sound in the speakers when you turn it on

the graphical garbage when you turn it on, or when reseting

it happens on MiSTer too, when you reset

magic

[tawdry plover]

Iconic

That boom is probably capacitors 🫣

[gilded flicker]

Or your speakers getting ready to blow out! Turn the volume down before that!! 😅

[unreal swallow]

yeah no boom sound on my cab 😅

[unreal swallow]

I do get the graphical garbage though

[wintry agate]

I get this green garbage screens only with unibios versions.

[slow grail]

I set metal slug to japan in unibios but it's still in SNES MK1 mode

[full raven]

This screen, yes in MVS system

but in AES is like a flash of graphic garbage... and in reseting a graphic deformation... IT'S NEOGEO !

[unreal swallow]

I was getting it with a standard US bios on a real MVS, but I am also using a cheap multicart

[lucid flume]

Has anyone here done an actual lever replacement on one of these?

[unreal swallow]

that stick is so purdy

[lucid flume]

[spice cradle]

wait, this isn't FPGA?

[fading verge]

They mention custom Asics. Wouldn't be surprised if it is just FPGA. A must buy for me really.

[slow grail]

fuck me.

[haughty veldt]

Okay @green marten , what is the track record of this company!? Will this thing be dog poop, or actually amazing?

[spice cradle]

the track record is Koch Media and they usually published games like Kingdom Come II

[sleek yew]

"Gameplay on the NEOGEO AES+ is not achieved through emulation - instead the console is powered by its legacy ASIC chips, re-engineered by modern standards to accurately replicate the original machine's hardware and software. The system natively plays game software from both new and old game cartridges for the most authentic retro gaming experience. Not emulation, not FPGA approximation, but true console reincarnation etched back into silicon."

Not FPGA approximation 😄

new mister FPGA should be named mister FPGA appromixate

[spice cradle]

https://plaionreplai.us/products/big-tournament-golf

wow, it's not some lame golf game, it's Neo Turf Masters with a romhack and a weird name

oh wait, this is how the game was called in japan?

[fading verge]

The question is will it allow MVS carts?

[little cosmos]

That’s not listed on the product page… would be great if it did

[green marten]

oh I am making fun of that fpga comment lol

[green marten]

they said no

[green marten]

working on vid now

I obv ordered one for the comparison vids

I never expect people to send me hardware

ill run a vid at 4

[indigo radish]

Wonderful

[green marten]

I got black. Because I dont need to pay $100 more to replicate shit I already own lol

I have an AES/MVS/MiSTer. This is a curiosity piece

[slow grail]

I wish the big version came in white

that white metal slug cart is

[strange grove]

i won't lie, this is actually pretty intriguing. be interested to see what the console is like and how it performs

an official neo turf masters release with the scotland course added in is enough to pique my interest

[ocean phoenix]

omg Neo geo

omg omg

[strange grove]

[ocean phoenix]

Omg this is the best reaction

[green marten]

OMG ROBBY ITS ROBBY

[strange grove]

a white neo geo console is cursed though ngl

[sleek yew]

will it become yellow like white SNES in 20 years ?

[strange grove]

hopefully. it wouldn't be authentic otherwise

[mystic geyser]

Will the core be updated to have AES+ mode?

[slow grail]

what is AES+ mode?

[sleek yew]

not possible on FPGA approximations

[slow grail]

finally, no emulation

I can't believe I bought a goddamned Neo Geo today. Hopefully MBS sends me a thankyou

[north depot]

Apparently Plaion's line of Replai products are legit: https://plaionreplai.com/collections/consoles

[strange grove]

can we just get a cheap neo geo flash cart now please and thank you

[north depot]

They were the ones that made the Atari 2600+ console.

[unreal swallow]

it’d be cool if they made new MVS carts too 🥲

[mystic geyser]

It was a joke…but then why can’t it?

[wintry agate]

Plaion (ex Koch Media) is trustworthy. Very good news for Neo Geo fans.

[south cloud]

Our mutual reply : Your ego's writin' checks your body can't cash.

We'll see, in due time.

[green marten]

haha I talk about this in my vid...we shall see. I did knock them a bit on the FPGA part but said "I get it. you want to sell consoles" and basically said "I want it to be perfect. But even recreating the silicon on moden processes does not mean perfection"

I wonder if they approached Furrtek

[south cloud]

Not sure, or else he'd be in serious trouble and would need money.

This is not the kind of person who agrees to work directly or indirectly with the prince of the United Arab Emirates.

[umbral zinc]

I wonder what the hardware they’re using is

[green marten]

they can be interesting lol

[mystic geyser]

[green marten]

and I am sure some of those comments will appear in the vid but...sigh...what can you do

running the vid at 2 to be done with it haha

[peak girder]

I need to see if unibios is compatible with this

[green marten]

would be a big miss if not

the question is flash carts. My guess is...no? Even though I didnt say it in the video as I dont make guesses that seem negative but it seems like their ecosystem is selling games too so flash carts kind of negate that. No AES collector is going to switch to repros

[fickle hollow]

"legacy chips re-engineered by modern standards to replicate the original machine's hardware"?

[soft juniper]

how would they prevent flash carts?

If it truly is an "exact" "no compromise" "non fpga approximate" implementation 😄

[spice cradle]

very weirdly specific "incompatibility issue"

[soft juniper]

except flash carts tend to use reprogrammable fpgas to get around those issues....well, maybe if the flash carts ever get updated 😉

I suspect the big win here would be manufacturing the components to make the carts in such volume that they keep the costs low, hence the $89 games

[green marten]

They could find a way. At least temporarily

[peak girder]

If it’s the same exact board as the AES original that they’re using, then I don’t see why a unibios can’t be installed into the console

I wish it had sd card support so you could just put the unibios hack on an sd card and boom lol

[strange grove]

yeah, an SD card slot would be huge

[green marten]

I’m sure it’s just a flash chip on a PCB with a few components to traces out to the cart slot. Biggest game is 7XX mbit so it’s well under a 100mb file. 128MB rom and off to the races

So def cheap at volume. Most expensive thing is probably the license

And I would guess, if they were smart, they got in contact with whoever already produced the molds for aftermarket snap lock cases. Tool and die isn’t cheap but they are already done so why not try and get in on that

Even if they had to pop in a dozen flash roms and separate code from graphics data from audio data it’s still tiny chips these days in volume

[ocean phoenix]

I want to get it as I actually own a small collection of AES games, but it’s a lotta money and I just use MiSTer lol

[green marten]

I bought it...because of course I did

but just the base console with stick and Neo Turf Masters

[ocean phoenix]

Well you can make your money back on it with a video

[green marten]

unboxing and review / comparisons to AES / comparisons to MiSTer...yeah break even point

because holy shit I dont need another way to play AES lol

[ocean phoenix]

Not minimizing your purchase of it at all, but like, I get it. You need to buy one for your channel.

[green marten]

AES/MVS/CD/CDX/MiSTers/Pocket...Neo Geo is coming outta my ass

[ocean phoenix]

I wish I had a legitimate reason to buy one lol

[green marten]

haha yeah at this point I am so well known for Neo Geo / Hyper Neo Geo / 3DO and comparing shit...how could I not

also this is my wheelhouse...how many channels can put an original Mark of the Wolves AES cart in their AES and then AES+ and compare them? only morons like me

[soft juniper]

make sure you put in an original legend of success joe first

[green marten]

is there any other game on neo geo?

[fickle hollow]

8-man

[green marten]

"WHY DID YOU JUST TEST MATRIMELEE FOR THE ENTIRE VIDEO"....(drops mic and walks away)

[still gorge]

So uhhh for those of us who don't buy the AES+ do the turbo cores actually work now or are they still basically Metal Slug turbo only

[lucid flume]

Metal slug turbo only from what I gather, but I could be wrong.

[slow grail]

I mean, you can load any game you want on the metal slug core

but they are all cursed

[green marten]

Slugs R'Us

[prime star]

AES+ mode?

[covert lantern]

I just heard about the plaion system and headed here to see what everyone is saying. So my understanding from what I'm reading here is that despite the claims, it's most likely an fpga situation? And secondly, there's a metal slug turbo core that (I assume) doesn't have the slow down that the OG core has?

[green marten]

they specifically state its not an FPGA chip
