So it looks like a hybrid between LZ and RLE? amirite?

RLE is effectively a special case of LZ.

So are you going to write some formal documentation on this format and submit it?

How do I submit something?

Submit Files (http://www.romhacking.net/submitfiles/).

It's in the left pane. Basically you have to host your text document (TXT, PDF etc.) somewhere freely accessible on the web (hints as to where to host are in the help on that page) and write an entry for it. Then staff will decide whether or not it's worthwhile having on the site, also based on the correctness of the submission form.

So basically some documentation as to how it works beside source code would do in my opinion. Of course you can also stick source code in there.

A friend mine has a tiny LZE compressor/decompressor optimized (compressed files are a bit smaller than the original compressed)

You can download it from http://www.sendspace.com/file/he0wlp

Syntax: lze -c|-d file1 file2 [-l]

-c ... compress file1 to file2
-d ... decomrpess file2 to fil1
-l ... create log file (for test purposes)

Link is broken... Has anyone else downloaded the program? Please, send me a copy to give it a try or upload it. Thank you

Is there a sample file to test a decompressor against?
