Which version of assembly does OllyDbg disassemble binary to?

So I understand that there are many assemblers such as MASM, FASM, NASM, etc.

But which version is the disassembler in OllyDbg and Cheat Engine?

Unless you already know, OllyDBG only supports (afaik) the x86 instruction set. So, what you're seeing will always be 8/16/32-bit instructions.

MASM, FASM and NASM are all based on the Intel syntax (as opposed to AT&T version which is primarily used on Unix by GAS), but are in themselves different (feature-wise).

OllyDBG disassembles to MASM syntax by default. You can change this by going to Options -> Options...

Wikipedia gives a good example of Intel vs AT&T syntax: http://en.wikipedia.org/wiki/X86_assembly_language#Syntax
