Amiga MOD Packers Described - Module Protector Described

Format name : Module Protector
Created by : Matrix / LSD (David Counter 1992)

Sources :
* Arise & Drinks 40kb tracktro
* Converted MODs with NoiseConverter
* 3 files sent by Gryzor (thx !)

Gryzor states there can be an ID at the beginning of a Module Protector packed file. Now, in the small exemple written in Pro-Wizard doc, there IS a 'TRK1' ID in the header and all the description below is starting right after ... just add 4 bytes at each offset if the ID is there :). (Hi nicolas)

The following is repeated 31 times
with 8 bytes description for one sample

OFFSET	SIZE (bytes)	COMMENT
0 2 3 4 6	2 1 1 2 2	- Sample Size / 2 - Finetune (0 -> F) - Volume (0 - 40h) - Loop Start / 2 - Loop Size / 2

- Size of pattern table
- NoiseTracker restart byte ($7F)
- Pattern table
- ?!? wheter it's $00000000 or it is the beginning of the pattern data. BUT, a note COULD be $00000000 ! ... so, how do we process here ?!?. Pro-Wizard seems to test if it's empty ... if so, it bypass these 4 bytes and begins the pattern data right after
- Pattern datas (stored like Ptk) (one pattern is 1024 ($400) bytes)

Follow Sample datas stored like Protracker. Nothing is packed..
