Yes, thats also what i suggested ;)

 

For a start, these are the entry points of the rom routines:

 

offsets between us and other languages for most roms:

german: $5a

french: $78

uk: 0

spanish: $86

italian: $68

swedish: $78

swiss/f: $86

swiss/g: $86

czech: $5a (unofficial, patched german version)

For gemdos, there are two addresses. The first one is the entry point as entered in the trap vector. But that one only handles Super() calls, and checking whether being called from Supervisor or not. The actual dispatch function is the 2nd address, which is a C-Function.

 

I'm only a bit unsure about the 102(spanish) and 102(swedish) versions. For all other ROMs, the offsets menioned above are valid, only for those two being different. Maybe the images i downloaded are already some patched versions.

 

4.92 is also special, since it relocates itself to $f902 in RAM before doing anything else.
