A Blank Screen
A blank or freezing screen usually means the display list send to the RSP has an error it and didn't complete. This can be caused by a number of things. Some import details to look out for.
- The z buffer and color buffer must be aligned to a 64 byte boundary
- Any use of gSPDisplayList must point to a valid display list
- Pointers passed to the RSP specify their segment, eg use OS_K0_TO_PHYSICAL when passing pointers
- Any display list called with gSPDisplayList must end with gsSPEndDisplayList
