Snes9x-Next on Gamecube glitchy?

Hi guys, I recently bought a memory card SD adapter and finally got into the gamecube emulation scene with retroarch.

I mainly downloaded retroarch so I could play SNES games on it but the games I’ve tried have been glitchy (e.g. Donkey Kong Country, Yoshi’s Island), both of them showing garbage on the screen and having frame rate issues.

Is this common for Snes9x Next on the gamecube? Do gamecube users have a way to fix it?

What release of RetroArch are you using and what non-default settings have you made?

Glitchy video is often caused by the ‘crop overscan’ option. Be sure to disable it. Frame rate issues are usually just a result of not enough CPU grunt, unfortunately.
