Hey all,
I'd like to know how to retrieve the calc's ID. I wanna use it to make password protected programs, that are, almost, uncrackable. Since I do not have a clue about the place it's stored at, I'd appreciate if anyone could help me with it.
Greetings, Arriopolis.
You can look up the calculator id by [2nd][mem][1], I don't know how you would do that in a program without using libraries.
You can access the certificate from asm. Here is a page about the cert.:

This code loads 5 bytes (10 digits) of the ID into Op4:
Code: _GetSerial .equ $807E bcall(_ZeroOp1)
bcall(_Op1ToOp4)
bcall(_GetSerial)
ld hl,Op4
