I think you would just use the "d" sets instead of the "nd" sets. For example, you have mslug5 which is the large parent. Then instead of using mslug5nd you would use mslug5d. Mslug5d still has the same decrypted C ROMS that mslug5nd uses, but still uses the P, V, and M ROMS from mslug5. The C ROMS are where most of the space savings come in when decrypted. thanks for the info, i fixed them.. one thing,i know on some games kof 2001 for example the plus version unlocks the bosses so you can use them.. what about mslug 4 n 5? kof2003d seems glitched out.. lol
