I cracked a game once myself (on a dare from a hardware type who thought it could not be done). The NOPs (plural, note) needed to be placed in several subroutine overlays that came into memory XOR-ROTATED, the game repeatedly clobbered all the interrupt vectors the debugger depended on, etc. Took me three days. This stuff is NOT always easy, folks.

Reminds me of watching a guy at work replacing in turn each JP command in a game with a NOP to get around the reg code check. Took hardly any time and it was boringly sinple...
