Hello, first time posting...yeah love this site

Anyway, my problem is that I was messing with the configurations of the emulator whilst getting ready to play an snes game. Unfortunately, I set the resolution of the emulator higher then my computer can handle (put in a custom resolution) and now when I fire up a game I get a black screen. Note the game is still working (I can here audio, it still takes controller input, and when I hit escape I can tell the menu pops up) so it is not crashing.

(I know this was fairly dumb on my part but I have gotten other programs to fit my screen by telling the program to use a higher resolution then my computer it stretches the screen and gets rid of any black on the sides)

I have thought of a couple ways to fix this but I not sure how to do them.
 
The first and probably simplest would be to force run a game in window mode, this would let me get to the options screen and change the resolution there. Unfortunately, I don't know how to do this.

The second was to go into the emulators configurations folder on my PC and change it manually to a resolution that works, but I couldn't find a configurations folder which had information that pertained to inputs and resolution.
 
If anyone could tell me how to do one of these options or has some other way to fix this problem it would be most appreciated.

You can probably switch back to windowed mode by pressing Alt + Enter.

Does that work?

Alright, that did the trick!   Thank you very much
