My name is infidelity. I've been developing an MMC5 romhack of The Legend of Zelda. It's 2mb in size. 1mb PRG-ROM & 1mb CHR-ROM. The problem with the latest version of FCE GX 3.3.4, is that it's using an old FCEUX core, that was lacking the proper MMC5 emulation of the register $5130, which allows the mapper to read 3 additional pages of CHR-ROM within the rom.
