The aim of the patch is to be a starting off point in all seriousness. The problem is definitely the map sizes. The problem with changing map sizes with advancemap is that it moves the data around, including Header locations, usually to the 720000 area, as such, when it was decapitalising the headers, your header was in a different location causing conflict. The rom does have to be completely new due to the decapitalisation, and I don't apologize for that. That's the point of a rombase, if it were a simple patch I'd understand you, but this is designed to be a starting point. Don't worry though, for future updates I'll be releasing two patches, one will be for blank fire red roms, and one will be for roms that have already been patched with the rombase. This'll mean it won't decapitalise everything again, it'll only apply fixes to previously capitalised things I had missed and of course extra moves.
