I am going to move to asm at the moment to help out with my reverse engineering knowledge. I wanted an assembler that supports both linux and windows, but i've been struggling in choosing between nasm or fasm, because they both have there ups and downs and seem quite popular. Has anybody has experience with them in the reverese enineering field, or any advice on other possible solutions?

Of the two I'd go with fasm since it's efficient (being written with and can assemble itself) and supports many features for its size. Nasm just seems incredibly bloated in comparison.

Actually I'd prefer TASM or one of the tiny assemblers I've written...

hi Crystal321,

i never used fasm, but I can give you my opinion about nasm - I use it on linux and cygwin, its simple, powerful and works well. Maybe about fasm one could say the same? I just googled it, it looks also good

I think it does not matter too much, take the one which looks more sympathic to you and go for it. It should not be difficult to try the other later.



which would then be? when they could be a choice, why dont you name them?

You probably won't know what I'm talking about if I named them.

Lasm, Lasm32, LXasm, Ah40, L

haha LLXX,

man, i meant it like this: if you want to recommend assemblers to somebody who asks for them, you could have given a name and link to them (as they might be "unknown" and are your own), so the asking person would be helped to make a choice
ok i "give up" (shut up)

I'd also go with fasm .. small and efficient .. + it has a good support (forum etc) and its being updated very frequently..

I personally use fasm as well.. along with the RadASM IDE, which supports it quite well. Using gORC as my resource compiler and voila..
