This patch adds big-endian compatibility in gpsp (in general but only
for the interpreter). There's no performance hit for little-endian
platforms (should be a no-op) and only add a small overhead in memory
accesses for big-endian platforms.
Most memory accesses are wrapped with a byteswap instruction and I/O reg
accesses are also rewired for proper access (using macros). Video
rendering has been fixed to also do byteswaps but there's a couple of
games and rendering modes that still seem broken (but they amount to
less than 20 games in my tests with 1K ROMs).
This also adds build rules and CI for NGC/WII/WIIU (untested)
This causes crashes in PSP quite often in many games. Other CPUs might
(depending on the processor state) silently return zero or some
undefined value.
The fix is borrowed from ReGBA's codebase
this also changes how direct sound channels are started and
sample step precision is increased to hopefully fix gbc + direct
channel desync that has been reported on the forums.
