This uses BSON as savestate format, to allow external tools to parse it
(so that we can add proper test of the states). The BSON is not 100%
correct according to spec (no ordered keys) but can be parsed by most
libraries.
This fixes also a bug in the savestate palette color recalculation that
was wrongly overwritting the original palette (which could cause some
problems on some games).
Also fixes some potential issues by serializing some more stuff and
cleans up unused stuff.
Testing shows that states look good and there's only minor differences
in audio ticks, related to buffer sizes (since buffer flushes are
de-synced from video frames due to different frequency).
This is not needed at all, since the variables are not updated between
reload and end-of-frame (where we take our savestates). Added a reload
call during gba_load_state() to initialize it from the I/O regs.
This is the format used by PS2.
This requires fixing the palette conversion routines (and palette writes
in the MIPS dynarec) but also adding support for 555 mode blending
(currently only 565 modes are supported, regardless of whether they are
RGB or BGR).
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)
