ROM gives error and graphics problem

Problem 1:

in Megaman 64, there are some things that i am unable to see. like, refractors and roll in a cutscene where she says: 'what do you think your'e doing', or something the like.according to the FAQ, i should enable something in the graphics options. i have done every single input i can think off, but it doen't work. wel, it dos work for the refractors. do i need a different plugin?

Problem 2:

in Megaman 64, i've been to the first sub-city. i got the dreamers key, and tried to walk out. however, once i go out of the door that would normally take me back to the surface, the ROM crashes! what must i do to stop this? i don't think it's a bad ROM.

specs eh? not sure what you want, but this is what i could find.
