Relocating MTX Machine Code

[Martin A]

Absolute instructions include CALL nn instructions and LD instructions such as LD a,(nn) or block move instructions accessing data within the loaded code, not just JP instructions.

I Imagine the real killer trio would be the calculated jumps

Code: Select all

JP (HL)
JP (IX)
JP (IY) 

oh and nearly forgot Memotech's trick, that both the CPM rom and system rom use:

Code: Select all

LD HL,exitRoutine
PUSH HL
... half a gazillion lines of code
RET    ; indirect jump to exitRoutine

Automatically working out where they get their address from could be "tricky".

Aye, one of the joys of Z80 machine code, all the "flexible" ways of doing things
