I've been working on a cheat table, but when the value changes there are no "add" or "sub" opcodes unlike in the CE tutorial. How did those people manage to do it?

I think you have the misconception that there must be an 'add' or 'sub' opcode for every write to an address.

Generally, that's not the case; there are various representations of how a write to an address may look (most commonly involving the 'mov' instruction or its variations).

For example...

Code:
movss [rsi+4C], xmm0

inc [eax+4]

mov word ptr [rbx+14C],rcx

fstp dword ptr [edx+20]

dec [rax+4]

mov [eax+esi*4],ecx

And let's not forget these:
Code:

mov [ebx],eax
mov [edi+ecx*8+20],eax


From what I've seen, add and sub are more often used with registers than addresses.
