Edit: v1.4b released, now you can choose your compiler/emulator if you don't like the built in ones :p
also you no longer need to uninstall the old version and then install the new one, this is a patch update so that means v1.3.4b must be installed for this one to work.
Instructions: download patch, run patch, choose directory that old version was installed in, it will update the necessary files.

Cool. Using TASM and pindurTI comes into mind.

I am teaming with Eeems to do this. I think we should add what Spencer mentioned in Revsoft forums. He suggest important features.
I can do the code counter immediately by seeing the source code that calls SPASM.
Later I can try to come with a Linux package. Unfortunately a Mac package is not in my reach.

While playing against computer I always feared cheating...
I like the idea of the board game! I am going to play it... I enjoy table games and I was looking something new like that one.

About A.I.
There are some RTS that the computer gets extra resources outcome to have advantage.
Some AI only attack you if they have more points/army than you. Coward AI... Even in fog playing.

I like the new style more than the older, dunno why, just like it.

I never used or knew the .com and .net domains.

The omnimaga.dyndns.org I know because of the way back machine...

I think DJ is not happy because he is eating too much for one lunch. j/k
News with barely 2 lines?

Nice code.

I also like tricks with instring( and sub( together. They are pretty efficient.

There are other things to add.

The code counter is the most important but spasm can bring statistics, symbol table and generate listing. The switches in the command line are documented in spasm docs found in the svn in RevSoft.
A sprite editor would be cool, too.
Some file explorer on the left side.
On top some quick access to the usual Open, Save, Undo, Redo, etc. and others like Assemble.
Allow editing in some tabs. (better limit to 10 because of memory usage)

Since XULrunner is cross-platform, you should add a package to Linux and Mac someday.

I saw the source (shiny source code and seems well done). Can you get the stderr and stdout to an called program with JavaScript? Wikipedia to know what stderr and stdout are.

If you can capture it and show to the user, to see any errors SPASM throws (like in the command line).

Here a pseudo code to do it:
- Get the text selection with assembly code to be counted
- Write to a temp file
- Call spasm with -C -O switches and point input to temp file (-C for counting and -O for no output)
- Delete the temp file
- See in stderr or stdout the bytes and clock cycles
- Alert the user the result

Basically is what my PHP script does. xD
