PSPgenesis 1.17 rom problem

[LostBattousai]

When I try to play rom of Spider-Man vs. The Kingpin i notice that when I make spiderman walk the character
animation stutters. Also, when I try to crawl on the ground the character will slowly move forward and quickly alternate between a standing and a crouched position as if the down button is on rappid fire. I tried the rom on my computer with the wgens emulator and it worked fine so I know it isn't a bad rom. Has anyone else had this problem with this game or any other game?

I would also like to know if there are any other Genesis emulators for the psp that work with firmware 2.71 and eloader .99.

I would appreciate any help anyone could give me on these subjects.

Thanks for the response but I am new at this and afraid of bricking my psp... is there anything that will solve my rom problem that dosn't involve changing my firmware?

If you have a 1.50, you could try running the rom through DGen instead.
