It reminds me those times I thought EGCG team... well in fact Eddids, was about to add Cham-Cham and Zankuro from PS1 to Neo-Geo version of Samurai Shodown IV.
He was doing an excellent job by switching roms size to allow more space and include new things there.
If I'm not wrong, he was involved in those KOF PS1 and PS2 hack versions for some KOF games.
do you play old retro games on ps1? Which emulator do you use?
For me the best is DuckStation these days.
