thnx ppl.
i can play them via nesDS and it will cost less storage, but i'm afraid of going through it and nesDS will cause a problem and keeps me away from progressing.
i think using gba rom is more proper, since i have bed memories of not finishing link to the past for losing my saves. even in REAL cartridge, fck.
If you just trim the roms they will use about the same space.
Actually, the saves are waaay bigger than the games themselves
I'm currently trying to make some IPS patches, give me some time please.
Edit: OK, these are all of the games, right?
