I would like that too, but i dont think there is specific books or tutorials how to understand CE assembly
I tried to look for tutorials but all i can find is the 'real assembly' and that stuff is different, at least for me.

You can check wiki for all the instructions and stuff http://en.wikipedia.org/wiki/X86_instruction_listings

Also your code says move -32 to an address at esp+04 i think

And the code you posted changes one byte to -32 (in hex) on [esp+04].

CE has some specific instructions for making scripts, but otherwise it's using the normal asm instructions.

If you don't want to read through an instruction reference and check all of the common instructions, you can also check the help file of CE, which has an explanation for the most common instructions. And there are literally hundreds of sources for these instructions. Just google it. The link that I gave you also explains these instructions.
