bunch of probs

[spankbank]

ok i load up perfect dark and i get this error "invalid value written to sp_mem_addr_reg
pc=0x234
value=0xbl20 continue?

i click yes and it loads the game ( a bit laggy but it goes)

then after playing awhile it gives me this

trying to write 32 to unhandled of invalid memory at address 0x1115946, continue?

i click yes and then it just keeps popping up and i cant play.

my comp is real nice so i dont think its that. Im a real noob to this but i like it.
