Unibios Pick N Mix

[Lyric Maro]

HiI wanted to share my solution to boot on the unibios by default (and not having to switch bios by the mame menu).This seems to work fine with mame 2014.I unzipped my neogeo.zip and renamed the uni-bios-3_1.rom in sp-s2.sp1I now have a warning message (that some rom may be incorrect) but I start on unibios.It seems to work fine.

In the Edit Emulator screen for that emulator entry set your default command parameters to aes and turn on "Use File Name Only". Also don't forget to add the platform name in the Associated Platforms tab.

Fair enough, I was just curious because it seems even people into the real NeoGeo hardware seem to like and prefer the Unibios because it gives you the option to pick AES or MVS and region easily. I wouldn't think to really call it a mod or a hack unless you are using the cheats.

I get intro warning: "One or more roms/CHDs from this machine are incorrect..." sound cracking sound in all AES games. Running the latest Mame 0.234 with the latest Mame 0.234 SL AES with LB mame command -keyboardprovider dinput aes %romfile% -bios Euro. I updated my audio interface, redownloaded SL AES romset. The issue remain. The MVS roms run without cracking sound. Anyone got solution?

It could be a problem with your actual NeoGeo bios. Do you get the warning with every game?

Try the NeoGeo.zip you're using for AES in standalone MAME. Do an audit and see what files are missing or corrupt. You should be able to work out from there if that's the problem. If so you need to get the updated zip.

I use the latest merged set so i don't need to neogeo.zip. Yes, i get the warning with every game even though i redownloaded the merged romset. Also, i downloaded the latest split romset and the same issue remain. What do you mean by audit?

In standalone MAME you can right click any game and select 'audit'. This lets you take a look if any of the files pass a check. If you do that with a handful of your crackly Neo Geo titles, and it's the same file missing or corrupt with every game... well, it could be the merged bios inside your games, one of the .rom files is an older version.

If they pass the audit with no checksum errors or missing files obviously the problem lays elsewhere.

Merged sets do not have the bios included in the actual rom files. If you have a complete rom set then you do have a neogeo.zip file and if you don't have one you will need to find one because it is required for Split and Merged sets. It is the Non-Merged set that has the bios included in the actual game rom zip file.

If neogeo.zip is required for my merged set then how come the AES games run in the first place? The SL Merged AES full romset is from pleasuresdome. Anyway, i put the latest neogeo.zip (bios) from "MAME 0.234 ROMs (bios-devices)" inside the neogeo AES roms folder, run games but the sound issue remain. This is how my rompath looks like in mame.ini: rompath "roms;X:\Roms\MAME 0.234 ROMs (merged);X:\Roms\MAME 0.232 CHDs (merged);X:\Roms\MAME 0.234 Software List ROMs (merged)",

Btw, my default command line parameters for mame in LB edit emulator is "-keyboardprovider dinput aes %romfile% -bios japan", how to make mame favor usa/world region? usa/europe instead of japan cause warning message when launching a game "One or more roms/CHDs from this machine are incorrect...".

If you tell MAME to open a rom and use unibios, how do you tell unibios you want AES mode?

Say I launch Metal Slug using "mame.exe -bios unibios40 mslug" the bios is set to MVS by default and I can't see how to change it to AES

Howdy do folks! Usually I post in the water cooler but I thought this might warrant a discussion. Neo Geo is way out of my league of knowledge and rather than Google myself to death I thought it might be fun to get some opinions of our esteemed members.

I personally opted for a Neo Geo CD because you're getting virtually all the same games as AES at a fraction of the price (usually). Of course, you do have to deal with load times, but I don't think they're as bad as they're made out to be.

I've got a 4-slot 'Big Red' MVS cab with kits and an AES w/ROM cart, and I would say that an AES + Terraonion ROM cart (same as an Everdrive, really) is far more practical and economical. With a little patience and consistent looking, you can get a Japanese AES (they are region free) for a couple to few hundred (depending on if you want loose or complete and since the USD is outpacing the Yen by quite a bit), and the ROM cart for a few hundred more (I had pre-ordered mine through Stone Age Gamer); get the HD Retrovision component cables, and you're off to the races

MVS is absolutely the way to go, as it has been since forever. Games aren't as dirt cheap as they have been, but compared to how much NES and SNES games, etc. have gone up, MVS isn't too far removed, and the motherboard ("console") system itself is still super cheap because they are so ubiquitous.

There are a few really cool titles that'll set you back over $100, but the majority of interesting games can be acquired for less, including every Metal Slug lower than 4 (ie. the good ones).

If you're going with an AES console, definitely get a cart adapter. But honestly unless you really want your setup to look sleek, I'd just get a single-slot MVS motherboard and hook it up to your TV with a cheap supergun - no reason to modify it right off the bat IMO, and while a unibios is cool, it's by no means mandatory - I had my neo geo for nearly two decades before I got one.

Also, the RGB output from an MVS is better than what you get from an AES anyway.

I won't argue that this is the best way. This is just the way that worked out for me. I own a consolized MVS that has component output and controller inputs for Neo Geo controllers and Saturn controllers. For the most part, I just play the 151 in 1 cart because I don't want to put a lot of money into the games. It's not perfect, but it allows me to scratch that Neo Geo itch whenever it comes up. The controllers are setup with a "credit" button which functions as inserting a coin. So you can push that button as often as needed to continue playing. The console itself takes up about the same about of space as an SNES and the board sits inside a custom made case that gives it a clean look.

Not sure exactly what kind of experience you are after, but the best way in 2024? It's certainly emulation. It's just about perfect and much cheaper! Others mentioned NGCD but I would dissuade you from that option, mainly because not every Neo game is available on CD. Plus, as a cart-based platform, waiting for loading times is just very un-Neo imo.

BUT it really is "just" emulation. It's an emulated Neo Geo on a modern flat LCD. You get the exact same experience out of just booting up MAME on your PC, except that comes with a bunch of other advantages as well. The big distinction to me between going the MVSX route or MAME is whether it's important to you that you own the games legit (and even then, every MVSX setup I've seen, has been loaded with pirated roms anyway, so they could play any Neo Geo game )
