Explanation... between the years and models there will be a lot of different roms as Mitsubishi changed things. The good news is you can flash different roms onto different ECUs. However you will need a manual and automatic rom, a MAF/MAP rom and MAP rom. Unless of course the MAP sensor is the same between markets in which case the MAF cars can just flash to MAP roms and make the MAF obsolete. However a MAF rom defined is not going to run the MAP only Cars. In addition the G4 will also need it's own definitions for Manual and Automatic and then MAF and MAP. There is some work involved, but it's been done before with other Mitsubishi's and can be done again.
The MAP roms are the way to go here, and if you can get the four needed MAP only roms (hatch manual, hatch auto, G4 manual, G4 Auto), it should cover the entire market we currently have in circulation. Sadly, I'm only seeing MAF roms so the MAP only guys may end up suffering.
