How to mod PS1 version of the game? I tried modding some files and then reinserting them to CD image, recreating CD image using program called psx mode2 or something like that. Everything worked at first but after some playtime it seems the game hangs/crashes at certain parts/moments whereas original CD image will not crash. Tried it the second time modding the same files (but slightly different) and then creating CD image the same way. Effect was pretty similiar. The game crashed/hanged but in different parts/moments whereas with original image it would be OK. So what is the deal with PS1 modding? How to do it effectively and which program to use to create CD image?
