Hey guys, what do the different ROMs in the Neo Geo do... for instance...

What is Sound, C?
What is Video, V?
And what is M?

Anyone?

Cx - The 'C' files carry the data needed for the lovely graphics you see, so if
a game has messed up graphics then its probably due to a bad C file, you can
usually replace the offending file with a correct one to fix the problem.
P1, - The P files contain the program data, so if a game has glitches or bugs
P2 in it (other than video or sound) then it's probably due to a bad P1 or P2
file (or both). A recent example I came across was when KoF95 would freeze
whenever a throw was done, replacing the P files solved the problem.
M1 - <Info needed>
S1 - <Info needed>
Vx - The V files contain all the sound effects and music for the game, if a game
has corrupt up sound or music, it's probably because of bad V files. Replace
them with fixed one's to enjoy the lovely music rather than having some
Godawful screeching noise.


Found this info... so now all I need to know is what does M1 and S1 do? <IMG SRC="smilies/smile.gif" border="0"> They are both really small, so I am not sure what they are used for. Usually see the M1 at around 127K. I am just trying to learn a little more about the inside of MVS carts, and if I ever have a problem, what I can know to look for! Thanks,

M1 is the Z80 code that controls the sound chip. S1 is the FIX layer graphics (top layer). Usually used for fonts, small game logo, enery bars, etc...

Px - 68000 game code
Vx - ADPCM sound samples
Cx - Graphic Tiles (sprites)

LOL, I was reckoning you'd be building guided missiles with that knowledge. <IMG SRC="smilies/wink.gif" border="0">
