Snes and Gen for 3.40 oe-a?

I tried to use snes9x for 3.40 oe-a firmware and when i did the eboot, it didn't load so i'm not sure if i have the right version or if snes or gen emulators will even work on this firmware. are there any emulators that work on 3.40 oe-a?

Every single one should. Make sure you have 1.50 kernal enabled on custom firmware,
and they should go in the GAME folder. If its not enabled just make a GAME150 folder next to the GAME folder, and put the emulators in there.
