User Reviews

  • Great tool. I was finding a compiler for old dos and this works very well. It's good to know this works with x64 as well.

  • Very good alternative to masm and tasm in most cases.

  • Great job!

  • A very good alternative to Masm, and a lot faster. Almost fully compatible, the remaining 0.1% are in the bugs list; before embarking on a bigger project, study that list, although usually these bugs have no relevance for the average user ;-)

  • I am starting to learn assemble language,it is the tool that I need.thanks
