I actually stopped when I updated to 2.80
2.80 does everything I need it to. Doing anything else is a waste of my time.
Thanks again for everyones help! Cheers
*EDIT*
As much as I wanted to downgrade, then update to custom firmware, the process was simply not worth it. Having to work with all these independantly created files, and the incredibly bad instructions they come with, was not worth the risk of "bricking" my new PSP just to run NES and SNES games once in a while. If I were to take more advantage of the firmware, I'd try to get through it. As it is, I'm fine with playing Contra on the big screen.
After going through this I can definitely see why people say that Sony killed the PSP.
