Do you know specifically how to reassign this? (I assume ahk means auto hotkey)
I looked in the keybinds menu for snes9x but the 'Quit snes9x' hotkey is currently unassigned, yet Esc still kills the program.
EDIT: Ok, I guess this was a Launchbox issue after all. For some reason there was some code in the AutoHotkey Script that was automatically added when I connected snes9x to Launchbox. I deleted that code and now all is good. Case closed?? It's functioning as intended, anyway. Thanks!
