I made a patch like this for Zero Mission already, and someone suggested I make it for Fusion as well. Basically, this makes selecting missiles and Power Bombs a bit more like Super, but not so much. What does that mean? Well, to arm missiles in the original you'd have to hold the R button. However, this patch makes 1 press of the R button arm missiles and another press of R disarm them. This is especially useful for those playing on an emulator on a mobile device, of for those who have keyboards that don't allow several inputs at once, (like mine).
