Gryph Posted January 24, 2004 Share Posted January 24, 2004 What's this P rom, S rom, V rom, C rom, and whatever else rom stuff? What do each do? I've been reading about that since I came here but never understood it. I now they are functional parts of ROMs but I don't know anymore than that.

Agozer Posted January 24, 2004 Share Posted January 24, 2004 P roms contain the program data.C roms contain the graphics.M1 rom contains the Z80/68k CPU calls/instructions.S1 rom contains the text.V roms contain samples/music. Link to comment Share on other sites More sharing options...

Weirdy Posted January 25, 2004 Share Posted January 25, 2004 encrypted pcb boars(the big versions of neo geo roms kof99 and later) don't use s1 roms. Only the decrypted sets(which are bootleg) use them Link to comment Share on other sites More sharing options...

Lestat Posted February 6, 2004 Share Posted February 6, 2004 I have some files that have m1d, and a m1. What does that mean. Also, could I rename a P2 to a S1 if the Kawaks rom audit tells me to look for it? Link to comment Share on other sites More sharing options...
Agozer Posted February 6, 2004 Share Posted February 6, 2004 (edited) I have some files that have m1d, and a m1. What does that mean. Also, could I rename a P2 to a S1 if the Kawaks rom audit tells me to look for it?m1d means that the rom file is part of a decrypted romset. No, you could not rename a P2 to an S1. Why? Because P2 handles the program code and S1 contains the text. How would a simple rename change anything? On an encrypted board the data of some rom is contained inside another rom data, to throw off dumpers. Renaming the file does not make the data usable.Alas, you can't substitute a rom file with another, different one.
