I’ve been having problems getting a lot of n64 games working on the mupen64plus that installs with the SD card image. Browsing around the forums it seemed that the mupen64plus-testing version might be a good way to go so I updated the setup script and then installed mupen64plus-testing. I know have a number of roms located in /home/pi/RetroPie/roms/n64-mupen64plus however the n64 emulator does not show up on the dashboard anymore since I updated to the testing version. Is there something I’m missing on how to get the testing version working and showing up on the dashboard?
I did. I wound up reformatting my SD card and installing the 3.0 beta 2 version of RetroPie to start with. I then found my answer in this thread. The testing version of mupen64plus seems to work much better.
