Topic: VLX to lisp

[TJAM51]

Can VLX be converted to LISP?

[deegeecees]

Try a Google on "VLX decompiler".

I believe they have tried to discourage that sort of thing.

[rkmcswain]

Not sure about VLX, but FAS can. I'm not encouraging it, I'm just saying I have seen it done.

Nah, neither can be "decompiled". That project was dropped.  It was very cool info that guy provided though.

[rkmcswain]

Yes, FAS can be "decompiled". To repeat, I have seen it done.

[JohnK]

Dude, the .fas format isnt really `compiled' so it cant be `decompiled'. The .fas format can only be "decrypted". ...Look in to it.

Now, like i said; there isnt a "tool" out there that i know of right now but the info is so people can build their own if they want. All the tools ive used were very rudimentary; you can do almost the same with a hex editor and a little snooping.

Whatever, you are talking semantics now.

The original question wasn't "is there a tool?" - the question was "can it be done?"

BTW: Who is this "guy" that you are talking about?

[JohnK]

Im talking about ``Dead_loop''.
Awhile back a guy posted on the news groups that he wanted to create a fas/vlx decompiler...

Needless to say, this topic soon got deleted along with his notes/tools.

No tool? then use a hex editor.

If you google the right words you will find that not only is ther a "tool"
to decompile/decrypted/dissasemble fas files it will also decompile/decrypted/dissasemble vlx
into fairly readable code
its not something I would endorse But the fact is there is a way to convert a vlx to lisp

[JohnK]

Have you used it?

Ive taken a look at a fas and vlx file and i noticed that there is basically no difference between a vlx and a fas file. The only difference is a small ``header'' or ``make file'' included in the vlx.

I will delve a bit deeper later.
