Perhaps he wants to get whatever the Axe source would be for a program that was written in ASM, not necessarily one that was written in Axe. Of course, that's even more impossible than trying to disassemble a program written in Axe back to its source.
If that's the case, that kind of makes my head hurt even thinking about it.

As far as I know, the only finished and released Mario games were written in z80 assembly, not Axe. So it sounds like you don't want an Axe disassembler, just a regular z80 disassembler.

However, unless the author of a program explicitly tells you that you can use their code in your own project, do not use their code. Even if it's not illegal, more importantly it's just not right.
Actually it includes the Asm source code

but It looks as if it is in Axe though

That file was submitted in 2001, so it was written at least 9 years prior to Axe's release.

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Possible: Yes
Feasible: No
And I'm sure Axe programmers wouldn't like it.

An Axe disassembler is nearly impossible for the following reasons:

-You lose the names of Pointers, Labels, and Variables
-You lose comments and code formatting
-You can't tell if specific data was a string, or number list, or sprite, or picture, etc.
-Each new version of axe changes the routines used so the disassembler would have to be rewritten each version
-Peephole opts make it even more difficult to disassemble.
-Axioms, inline assembly, and other things like that would not translate

It is however, fairly trivial to disassemble it to assembly, and then map native Axe routines and variable locations to the assembly program.  But you would definitely not be able to turn it back into Axe language unless you do it by hand or something.

A decompiler is most certainly possible, but it would require as much work as creating Axe itself. It's no trivial undertaking. It's not worth the trouble.
"No tools will make a man a skilled workman, or master of defense, nor be of any use to him who has not learned how to handle them, and has never bestowed any attention upon them. . . . Yes, [] the tools which would teach men their own use would be beyond price."—Plato's The Republic, circa 380 BC

Can someone make an Axe dissasembler (dissasembles Asm programs and gives source code) on calculator? That would be nice
Will do.

And this is SirCmpwn challenging the Universe limits! :P I wish him good luck although it is very unlikely to get fairly accurate code.

:( I lost the source of my awesome game. I have a rlly outdated backup, but I'd rather deasm my executable asm script.
If you like my work: why not give me an internet?

Axe Disassembling would be cool but, it's quite hard due to its compiled nature. Unfortunate that SirCmpWn is no longer among us, and this project may never come to fruition

A friend of mine (Natch) made a hex decompiler ; he wrote the code, I made the design (the home screen, and two bugfixes)

I gave an example, but it sometimes fails (it seems it's linked with Axe compilation ?) at the step "Name of the hex prgm ?", then quit, shut down, and retry

I gave a pack with the source and two libs needed

Do NOT ask me anything about the code, even Natch doesn't know how it works !

NEVER DECOMPILE : - already decompiled programs (you get a bugged program, and mem losses; - the decompiler itself (RAM clear if you set any split setting to "Yes"

Sometimes, the split settings create glitches (bytes half-cut, or program corruptions), so use them carefully

So all this does is convert an existing prog to its hex? Because i thought decompiling was a bit more ???

I wrote a 500-bytes equivalent in Axe a while ago that doesn't need any of your restrictions. It's called PROG2HEX, and what it does is simply getting a name from an input and unsquishing it in a program which has the same name starting with theta. http://www.ticalc.org/archives/files/fileinfo/449/44973.html
