So i have this:

CMP byte ptr [esi+0x8],3E

I need it to break if byte at [esi+0x8] is 3E.

I tried:

readBytes(readPointer(ESI+0x8), 1) == 3E

but it didnt work Sad

The comparison is a good start, but that's not where you break.
After the comparison, you need to make a jump to some dummy instruction where you will break.

E.g.
Code:
cmp byte ptr [esi+0x08],0x3E
jne short @f
nop
@@:

You'd set your breakpoint on the NOP - that will only break when you need it.
