yeah, using Kega Fusion for Sega, but didn't see a way to launch it and then just use "Q" like all my other games to exit the game. The values for quit in Fusion seem to be hardcoded to Shift+F4 or something like that, whereas everything else can be set to "Q".
I assume you're pasting that code into the 'extra' tab of the mgalaxy configuration for the Sega genesis systems, but that didn't do anything from what I could see. Just trying to avoid a button combination and just use a single letter like you can do in any other emulator. I can change the ini file for Fusion to have "FullScreen=1" and then it would launch in full, but the single key to quit I can't get working.
