Subject: merge gpu_unai with gpu_unai_old
X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2163da5d5d9f1d7b6b5324c55ea5352384c2d7b4;p=pcsx_rearmed.git

merge gpu_unai with gpu_unai_old

Can now switch between them during gameplay.
Specify GPU_UNAI_NO_OLD=1 to prevent compiling this in to save memory or
whatever. No big endian support.
