Thats one *cool* entity.



And I will offer some latitude here, a *decent* automatic disassembler
is not possible, either.  I mean, if the RosAsm disassembler is the
"best there is" and it break by just adding a NOP to a sequence of
print statements, there's not much hope for an automatic disassembler,
is there?


You can try the RosAsm disassembler on this file.

< http://www.szmyggenpv.com/Help.exe > (ca 335kb)

This file has been updated _several_ times since I posted about it the first time.
Its very easy to test. Just download RosAsm, and then open this exefile from the RosAsm's

File/Open menu.

Then, when the disassebler has finished, hit F5 to recompile.
The dissassembler will stop, pointing out an error at the following line:

;fld T§edx*2+Data0407B9E           ; DB 2C 55 9E 7B 40 00

just comment it out by inserting a ; (semicolon) in front of the line.

now, hit f6 and run the application. (Should be connected to the internet when you hit run), as the app will try to download the file : "http://www.szmyggenpv.com/MyHome.roa";, and if it cant find it, it will likly spawn some error message.

The app run flawlessly compared to original.

You know have the asm source of the app, even it was ripped from the exe prior to upload.

Cheers,
