I meant no disrespect, truly. As Bugtest said, I was only talking about the the file format's simplicity. I made the mistake of assuming you were curious and possibly open to the idea of learning the trade yourself. It really would be a great format to cut your teeth on. I was only attempting to be ...

This is a really good example of the simplest archive format possible. The archive begins with a 4 byte signature 'PFPK'. Immediately after that is an 32 bit integer telling you how many files are in the archive. Then it starts the file allocation table. Each entry consists of: Byte - Number of char...

Step through the entire file and Xor each byte by 0x84 to restore it.

Here let me give an example of the recoloring. This is the 'base' picture. http://bogna.best.net.pl/ao/map/jackstraw.gif Then this string is fed through an algorithm which parses it out and performs the color change. "BaseBias = 0x24, 0xddce, 132" The picture then becomes: http://bogna.bes...
