Converted the hack into another... hopefully better hack.
Check for IW/EWRAM addr bit and handle accesses to EWRAM by correcting
the base addr and the mirroring range.
Assumes that iwram and ewram buffers are at a distance multiple of 64KB
for speed (so that lw/sw offsets can be shared).
This fixes a variety of games that should have been present in
game_config.txt such as Ninja Cop, Star Wars JPB, Medal of Honor,
Spongebob, etc. Some of them were just missing regional versions of the
cart. It also fixes newer games and homebrew such as GoodBoy Galaxy.
This gets rid of the bloated memmap_win32.c in favour of a much simpler
wrapper. This will be needed in the future since the wrapper does not
support MAP_FIXED maps (necessary for some platforms)
Let's see, this should fix issues on platforms that do not support
running the emu at 59.73 FPS. We run the emu at fake 60fps, which means
we produce more audio samples than the original device.
Instead of missing samples (which produce cracks in the audio) we should
be producing some extra samples, which will result in a frame drop every
now and then (like every minute or so, so it's not noticeable).
