    So I was working on my Firered map yesterday, but today I can't load the ROM on Advance Map. I get the error message: ERROR: (EUnknownRomType) AdvanceMapError(12): Unknown Rom Type! This Rom cannot be edited with AdvanceMap.

    I'm really confused seen as it was working fine yesterday. Any help would be appreciated.

    try to rewrite your BIOS at hxd from 0 to 500 offset address, select data from the old (original) version
     
    You have to change ROM header to appropriate one. BPRE for fire red us, BPEE for emerald us etc. there's a tool named RHEA by hackmew which is easy to use if you don't know hex editing.
