#23 Missing instruction 2F

[Jeffrey van der Hoeven]

During execution of Ironman (great game by the way!), I encountered a missing instruction:
[cpu] Instruction failure at instruction 1143816658 (opcode 2fh): Unknown instruction (NULL) encountered at F9B:2E26

To reproduce, do the following:
Run Ironman
Play first level and win!
