From what I understand, only Glide64 is fully capable of running this game. Using the wrapper provided by Wonder ++, I could run the game on an Intel 845G with no graphics errors, ignoring the fact my FPS was in the single digits doing screen transitions. My integrated graphics chip is not even fully supported by the wrapper, while my friend's card is.
However, she winds up with this screen in a 2D block match:

Oddly, this does not occur in a 3D block match. This is basically the only thing wrong, we've tried multiple setting combinations and it doesn't get fixed on hers. Even if she matches my working settings it doesn't get fixed.
We tried both 1964 .99 and Project64 1.6. 1964 didn't work at all in her case (and barely worked in mine), and with Project64 we are at this point. Would anyone here have an idea of what's going on here?
(Yes, we know to disable hardware frame buffer emulation for this game and to turn read alpha on).
