If I change the suffix the emulator don't see the patch.
Also not all patches are ips files, some are in Ninja
format which can't be applied in emulators on-the-fly.
Maybe the best solution would be to apply a given rom with the different patches available for it, then create a 7zip archive.
Something like this
Chrono Trigger (Translated).7z/
Chrono Trigger (Italian).sfc
Chrono Trigger (German).sfc
Chrono Trigger (Russian).sfc
Just like a goodmerged set, however the question is does GB even support 7z archives ?
