    |   No.10105 AWJ Developer Dec 30, 2013, 04:34 | This bug seems to be caused by the SSE2 versions of the RGB utility functions (in emu/video/rgbsse.h), which are currently only used by 64-bit builds. If I modify emu/video/rgbutil.* to force use of the generic C implementation (emu/video/rgbgen.h), the green boxes go away. |
