Add regional versions of SNK MVS games

[3lc3z4r]

If you know how it works, MAME uses a unique BIOS for NEO GEO, and to get a regional variation you must select the startup BIOS.
(For example, the default is blood in Japanese regions, European regions allow more languages, and I think the US is European, but with fewer options.) Unlike other games or consoles (where the version is a standalone game).

What I want to know is if there is a way to add versions of the same game by changing the command line in launchbox. In my case, the only solution was to add MAME to the launchbox that has the command lines and from there add it as an additional application to the game.

If it was not understood, it would be something like when you click on game versions and the multiple versions appear, when you choose one, MAME runs with the BIOS of the chosen region.

I think what you're wanting to do is, using the same particular ROM (i.e. aof2.zip), have multiple "copies" of that ROM imported into LaunchBox, but each "copy" loads using a different BIOS.  It'll of course be the same physical file (aof2.zip), but seen 3 times.  i.e.

• aof2 (Jap BIOS)
• aof2 (Eu BIOS)
• aof2 (US BIOS)

How you'd accomplish this from the command line is to add the parameter i.e. -bios 16.  ("16" being the variable/number of the BIOS for that game as MAME sees it).

Unfortunately, this isn't possible for Additional Apps ('Alternate Versions') because you can't add Custom Command Line Parameters to them.

As a workaround (though not ideal), you can edit the individual Additional Apps and manually set them to do what you want.  Uncheck Use Emulator then add the path to MAME and the appropriate parameters (including the ROM name).

I'm going to try that. I always like to have as much variety as possible just in case, even in images.
