Why can't I compile
Code:
cmp qword ptr [rdx],'12345678'

because it's a string of more than 4 characters

cmp [address],imm32 can only compare 32 bit


you can use cmp [address],reg64 but you'll need to fill one of the registers with the value first

Oh my god... Is this a problem with the Cheat Engine compiler..? Will it be fixed in version 7.6? I tried it, and without using a string, the operand can indeed be filled with 8 bytes?

no, it's a limitation of the x86 and x86_64 instruction set

It can't. Maybe you're thinking of nibbles (half-bytes) instead of bytes.
