So, on emulator i've gotten Warioware D.I.Y. to run just fine, and everything runs normally (i'm using desmume ver. 9.10). That is, until i load a modified version of the rom (in my case, a text-edited version), the emulator decides to refuse saving the game in any way. When i try to savestate, the emulator closes. No matter what i do i can't seem to get a modified rom to work, but the emulator is able to save on an unmodified one. If anyone knows of a solution to this, i would really appreciate it.
