@SuperFromND Alright, I'll try it. Thanks again!

@addison Saw these images over on Reddit, and while I'm (understandably) partial to a different little endeavour involving the engine, it's also pretty neato that the original MUGEN engine can run on the Pi as well!

Ok update as I seem to have managed to get this working. The key for me was to follow all the instructions from @SuperFromND at the top of this post.

Once complete, when i tried to load the game i got "No config found for system mugen" and I was sent back to emulation station.

I eventually ended up editing my etc/emulationstation/es_systems.cfg file as per the below

Replace

<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS mugen %ROM%</command>

with

<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 PORT mugen %ROM%</command>

Restart emulation station and to my amazement - it worked!

retropie supports neither mugen nor the switch, so...

still dabbling with it not having much luck at the moment the bor portion of paintown runns pretty well but so far any attempts to utilize the mugen portion of paintown results in codedumps the main menu is pretty much all i have running in mugen right now and it also lags

Wine only emulates the operating system, the PC Diablo binaries are still x86 so will never run on a Pi. If you want to play Diablo, there is a PSX port.

Yes, N64 emulation is crap for many games, the Pi is weak and emulation is not that good anyway. A few games work well such as F-Zero X.

There are apparently some improvements to N64 emulators coming so maybe the situation will get better in the next few months or year.
