N64 Controller Woes

hansolo77

I bought an 8BitDo N64 controller so I can have a more realistic gameplay experience. I have the controller working perfectly with the Pi. It syncs with it during bootup and everything is good. However, I can't for the life of me make it work right in the emulators. The document posted here:

Is only somewhat helpful. Case in point... I don't know which settings to use. I'm wanting to use the lr-mupen64 core. Specifically because it works with RetroAchievements. So I use the settings they suggest for this core when mapping it in ES (The Yellow C buttons are mapped to the RetroPad Right Stick, and the Z-Trigger is mapped to the L2-Left Trigger button). Once I get into a game some of the buttons aren't working. For instance, the C-Left and C-Down are dead, as is the Z-Trigger button. Also interestingly, the L1-Left Shoulder seems to be doing the Z-Trigger action.

I've also tried using the standalone mupen64plus core, and it doesn't even load. The runcommand script doesn't change the setting. I've tried updating from source all the cores related, and nothing. I'm not sure if I screwed up something or not.

So my question going out to you guys is this.. What button mappings are you guys using, and what settings in the LR core are you using?

Anybody had any success with the mapping instructions posted here?
