Hope someone is still active and reading this. Your posts inspired me to pickup one of these, got it very cheap. I have successfully followed your instructions, and can get opendingux working to some extent. My sole intent is to be able to play some of my favourite NES games whilst away on holiday. The only emulator I can get to work is fceu, the default emulator it seems. I would love to get one working that had support for savestates. No matter what rootfs I use, or sandbox version, I cannot get any other NES emulator to work. The majority seem to try and load, black screen, then jump back to the menu. Can anyone offer any advice?
Thanks for all of your advice so far, it has been a big help.
