PSMonkey has posted some more WIP news about his Nintendo 64 Emulator for the PSP at his Site:

Bugs go down, compatibility goes up!

Ok so I made some dumb mistakes in the cop1 emulation.

1) I did not check for cop1 unstability.

2) I was storing a 2nd set of cop1 registers into the general cop1 registers (general reg stores float values, 2nd set is 32bit int that hold cop1 status).

Anyways with this fixed I lost a bit in the framerate department on some stuff. Yet I now have more games running as a result. Doom64 runs to the title screen and posibly beyond but cant tell since i get a white screen when i start a new game. Bust a move 2 also runs now but looks to crash in game on a bus error (still hunting this one out).

So that is about it. Sadly no calls for 3d instructions so I guess I am screwed. I will be starting up hle this week so we can start seeing some 3d (but I might spend more time on fixing texture stuff in the rdp).

Enjoy the title screen from doom.
