But IO (c) should also be catched ....
I took the Scramble 81 game, but I do not know if it's over me. The game runs from address 22411. I found one procedure referring to the keyboard at address 1981 (drop bomb). I can not find a reference to the directions and shot. Does this game work on interruptions?

'typing' - one key code is read at a time using the ROM routines.
'gaming' - direct reading of the keyboard rows using the IN instruction.
You need to load the target game into an emulator and identify where the movement code is located. This is the hardest bit.
Do you have a particular game in mind?
*note to self - perhaps add a feature in the EO debugger which breaks on an IO operation? Or a ROM call?
