according to intel:
Quote: | Protected Mode Exceptions
#GP(0)
If the destination is located in a non-writable segment. If a memory operand effective address is outside the CS, DS, ES, FS, or GS segment limit. If the DS, ES, FS, or GS register is used to access memory and it contains a null segment selector. |
so how do cheat engine make the memory region r/w executable? (in hex-dump)
what are these special functions that ce use? (to make readable blocks writable)

The thing here is actually #PF instead of #GP
But yeah, stuff like VirtualProtectEx or editing the page table entries manually
