Is it really that important? Which games need this? Maybe Wii can't support it properly, unfortunately.Thanks, seems the new GSU detection routine doesn't affect speed
But i'd like someone to check this PR made to upstream Snes9x for add SuperFX 8MB ROM emulation support:
https://github.com/snes9xgit/snes9x/pull/712/files
And adapt it for be able to use this feature but with always avoiding overloading the Wii RAM/CPU for not make the games too slower.
I just don't know a simple way to do it. Maybe using a virtual memory for Wii? IDK.
