Haha I actually fixed it, the psp system wasn't showing in es_systems.cfg since I kept my old custom one.
Showing up fine now!
I do have other questions though.
- Is there any performance advantages between .iso and .cso for psp?
- The N64 emulator only shows a limited square, like say it was set to 640x480, it only covers that much of the 1080p TV and the rest is black
- Are there optimized settings for the PSP?
