I promise not touch the program. Trust on me.
If there is an empty zone where to put the little routine, I can do it.
But I need plain code, not encrypted, not compacted. Also, the disassembly of the loader, as it was of great aid when I converted SWAP.

Are the Keyboard and joystick routines always on the same place?
Is the video mode always the same?
