Retroarch was the one big missing piece for PS Vita emulators. Retroarch is a platform on which several emulators run, including DOS, Genesis, NES, Super NES, and more. The latest nightly is now available for PS Vita 3.60 and HENkaku compatible (vpk format). This release apparently ships with 18 cores (18 emulators).
This is a very early build, and people are reporting issues with many of the included emulators. User Zeroba in our forums reports:
PicoDrive seems to crash when loading roms directly or from .zip Snes9x doesn’t load roms. CATSFC runs fine, but thinks the controller is in port 2. Options – Swap Joypad Gambatte won’t load roms Genesis_Plus_GX ran Sonic 2 just fine. Didn’t test very far though Save States seem to write, but they can’t be loaded. The files are there however. “Failed to load state from x”
At this point, the best you can do is experiment with the release and report issues/feedbacks/tips in the comments below or in the /talk thread.
Note: People are also mentioning that if you’re having issues downloading the file, setting your DNS to “automatic” helps solving the issue.
