The batch file has to be written just right to allow it to work within PAM or as a standalone, but I worked it out and include the sources and instructions in the package. I simply make a batch file, then use a BAT-to-EXE 'compiler', then use ResHack to insert the ICO (not needed, but looks better), then package it up using 7z SFX. My method for creating my portable app package is a bit different and actually more simplistic than using NSIS (which I used to use all the time back in my Baldur's Gate hacking days). While ImgBurn is not open source, it is freeware and very useful (it has a huge fan base).

I do realize the goal is to use open source software. This is my first attempt at doing such a thing as I just recently became interested in making some USB flash drives using PAM and began to see there were programs out there that were perfect for PAM but not yet properly implemented, so I tackled one of my favorites. I keep seeing references to people saying ImgBurn is portable, yet nobody has really put it together in a proper portable app package.
