Fixing a problem with a rom

[Fat-Matic06]

Is it possible to get rid of these two errors:

1: When I play Winback: Covert Ops, there is a really annoying grey box that hovers around, and sometimes it covers the whole screen, making it impossible to play.

2: In War Gods, I often get an error message that makes pj64 exit. It says:

Map_GPR_8Bit
Out of registers

I don't understand what any of it means. Any help or advice is appreciated. Thank you.

Umm, sorry for being a n00b, but where can I find this gamefaq?

EDIT: Never mind, i found it, ill be sure to post my hardware specs soon. Thanks so far.

EDIT: nvm all of this, I found the problem with Winback, but the GameFAQ just says to not play War Gods in fullscreen, and im not, but its not playable still, cause everysecond i get an error message.
