I’m using the B+ model and version 3.0 beta of retropie. I’ve tried all the separate emulators which are installed out of the box on 3.0 beta. I’ve tried to change video settings from high res to low res, nothing seems to work.
Hope this gives a better perspective.
ps: I’ve ordered the Pi 2B, which should be here today.
If you search “N64” using the search panel, you’ll find a lot of useful info.
Update your setup script, and you will be able to install the mupen64plus-testing emulators. I found that the mupen64plus- testing with the gles plug in runs the best overall, while the rice plugin runs Zelda better. MANY GAMES WILL NOT RUN PROPERLY NO MATTER WHAT YOU DO. That said, the Pi2 will do better than the B+ – you should set the overclock to “Pi2”. My memory setting is 256MB.
