Need two roms to found correctly
kof2k2nd.zip is the parent rom

In Kawaks this found correcty only using two roms

I checked a few games using this feature in hbmame against fba, it doesn't seem they exist in fba so i guess it means this feature doesn't exist ?

kof2k2omg8, kof2k2omg9 and kof2k2omg9b don't seem to use this though, so i'll check if i can get them to work in fba. Do you know if they are older or newer version of this hack ?

I got kof2k2omg8 loading with this :

};

STDROMPICKEXT(kof2k2omg8, kof2k2omg8, neogeo)
STD_ROM_FN(kof2k2omg8)

struct BurnDriver BurnDrvkof2k2omg8 = {
"kof2k2omg8", "kof2002", "neogeo", NULL, "2010",
"Kof2002 (Omega v0.8)\0", NULL, "bootleg", "KOF-ON Team",
NULL, NULL, NULL, NULL,
BDF_GAME_WORKING | BDF_CLONE | BDF_BOOTLEG, 2, HARDWARE_PREFIX_CARTRIDGE | HARDWARE_SNK_NEOGEO, GBF_VSFIGHT, FBF_KOF,

0x1000, 304, 224, 4, 3
};
--- End code ---
The graphics are messed up though, and i can't go past the select champ screen (i tried some additional HARDWARE_SNK_* flags, but all of them seemed to break the game further), so i guess it needs some additional things (i expected this), any idea what i should try doing next ?

PS : i'm mainly interested in the process of thought, not the final result :p.

Didn't thought about that. Yes it makes sense to use a init function which doesn't handle encryption.
