Here is something very old, but still very cool. Attached are txt files that when saved as com (16bit MS DOS binary executables) will run. Pure magic. It works in DOS, Win9x, Win2k and WinXP SP3. In Windows 7 (32bit) you can only run console apps as the ntvdm.exe wont allow the app to take over VGA.
I have encoded a few text files which can be run in a lab environment (Remember these are unknown ASCII executables after all ! ) Plus I am including the original com2txt ASCII binary and exe2com ASCII binary for further encoding experiments.
Download here and rename to com2txt.com : com2txt.doc
In case you need to convert a 16bit EXE into a COM then you can use the this : exe2com
These programs were not created by me but by some Japanese guy a long time ago. Anyways there is a source code to the converter which can be found online. I am including some example ASCII executables here to play with (Old games)
Remember to save these files with COM extensions.
Also Kaspersky Antivirus 2013 was released a few days back, so I’ve tested it here :
“I need a jug of wine and a book of poetry,
Half a loaf for a bite to eat,
Then you and I, seated in a deserted spot,
Will have more wealth than a Sultan’s realm.”
