First off, this is the best emulation platform I've tried so far. I'm blown away by your work and fully appreciate your time and energy to this project. DS3 works without issue, every game runs full speed on my Optiplex. Will be donating as soon as payday arrives this week. =).
Anywho, i have been using the Mupen64Plus Standalone with Glide64MK2 plugin, and setting the aspect ratio has no effect. i've tried per game, in the game settings. and the default game settings. Do I need to manually edit the Config?
