Rikerz, thanks for making this open source! I had some fun adding things:
Pretty self explanatory, you can bind the hotkey to edit many different parameters now.
Also there's a button that scrambles most of the Byte Corruption settings. This can be bound to a hotkey, so you can be super lazy and keep pressing the button until you get an interesting corruption.
The new range settings are for corrupting more complex/larger games. Doom, for instance, will crash if you corrupt the part with the map data, but you can corrupt pretty much everything else. So you can use the multi-range mode to work around the maps.
The unlabeled buttons in the middle are just used by the hotkey code.

I made these changes about 3 months ago, so I don't remember if there were any bugs left to fix. It looked OK when I tested it with SMB just now, but let me know if anything's broken.
