It's the emulator (lr-retro8). Masters of the Universe is already reported as non-working and I guess other games may have the same issues (either loading or during emulation).

Best to use the official Pico8 simulator and configure it in EmulationStation to launch the games with it (see this topic for an example configuration).

@g2000 hello @g2000 I'm Jameel Perkins Asking IS It possible For u to help me by watching this video please I Really Wanna try to see if I can get across to play GameCube N Wii games

?

@saku00 Well, the addition is now part of RetroPie, so you don't have to edit the file again if you update Dolphin.

@george-spiggott I found the solution:

in terminal type cd /opt/retropie/emulators/dolphin/bin/dolphin-emu

then type dolphin-emu and it will open dolphin

@mitu

alright, thats good to know,
i read that some others had issues playing other emulators afterwards, thankfully i didnt get no problems.

hi there, is there a way to install Supermodel on a raspberry pi version of Retropie ? would it run well on a Pi 4 8GB ?

You can symlinks some of the (larger) ROM folders to the external storage if you want to use both discs, otherwise you can just run all your ROMs from the external disc - https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/.
