I have only released the piece of code which is stable. I'm going on with 16bits decoders, and the parser.
Currently the parser does this :
$ ./unmo3 -d 1 -p 3 dannyelf_ll.mo3
Uncompressed size = 53448 (0xd0c8)
Offset in compressed data after decompression = 5216
Songname = Danny elfmania
Nb channels = 8
Song length = 60
Song restart = 0
Nb pattern = 41
Nb unique voice = 123
Nb instr = 31
Nb sample = 31
Ticks/row = 6
Initial tempo = 125
Song sequence = 0 0 1 2 3 4 5 6 [...]
Unique voice number for each pattern = 0 1 2 3 4 4 4 4 [...]
Pattern size table = 64 64 64 64 [...]
Voice data len table = 0xf9 0x5b 0xc5 [...]
Instr table =
Instr#0 name = Assembled by -moby-
Instr#1 name = Original simpsons
Why releasing the code and specs if nobody needs it ? To share your know-how of module compression.
So that every tracker authors can respect this standard and some others can improve it.
Example: why it was so difficult to write a modern tracker compatible with the de-facto standard FT2 ?
Because (to my knowledge) no source was available, and very few documentation : only the format of the module, and not how to play it. Take a look here (http://lclevy.free.fr/exotica/
), I have helped to gather and re(dis)cover information about module and replay algorithms.
I have made the same thing years ago about the Amiga filesystem : writing a solid specification and some code as a demonstration (http://lclevy.free.fr/adflib/
). It was designed to work with a first application : ADFopus. Then years ago, without any contact with me, ADFview adopted it (because of the documented API). More recently a 3rd application surprisely adopted it.
And of course each time, the authors send me bugs fixes, and even a C++ wrapper.
I think the tracker communauty has more to win to use open and standard fileformat, instead of closed and proprietary ones, like MO3 -today-. That's the idea behind my work on it.
Now you have the whole ideas behind my motivation : sharing knowledge, and improve know-how on a given topic.
