	     Digi Booster 1.x - module format
             ----------------

There  is  one  DB  format,  but  the old is a little bit different (but is
compatible with the new one). Here you have describtion:
([1] - data stored as one byte)
([2] - data stored as two bytes - word)
([4] - data stored as four bytes - long word)

offset |bytes| contents   | meaning

000000 |   4 | "DIGI"     | char Magic[4]
       |     |            | If you support different music file types
       |     |            | check these letters.

000004 |  16 | some texts | Not very important[16]

       |     |            | There is a version of Digi Booster which
000020 |   4 | "V1.x"     | made this file [4] - stored as ASCI
       |     |            |

000024 |   1 |            | Once again version of DB but stored as hex[1]
       |     |            | (protection against lamers).
       |     |            | eg. $14 means version 1.4.
       |     |            |
000025 |   1 |    (8)     | Number of channels used in module (always 8) [1]
       |     |            |
000026 |   1 |            | Pack pointer [1]
       |     |            | If 'Pack pointer' is zero, the pattern data
       |     |            | isn't crunched.
       |     |            | 1 means that is crunched

       |     |            | PatNum[1]
000046 |  1  |            | It specifies the number of different 
       |     |            | patterns this module has.

       |     |            | OrdNum[1]
000047 |  1  |            | It specifies the number of different 
       |     |            | orders (in editor POSITIONS) this module has.
-------+-----+------------+------------------------------------------------- 
000048 | 128 |            | Orders[1]
       |     |            | Here you have stored numbers of patterns which
       |     |            | the player will play

000176 | 124 |            | SamLens[4]
       |     |            | Here you have a sample lenghts
       |     |            | Number of samples in module is 31.

000300 | 124 |            | SamReps[4]

       |     |            | The old format (versions 1.0-1.3) hasn't play
       |     |            | finetunes but has store it in module.
       |     |            | So. if version of mod. is 1.0-1.3 you have
       |     |            | to clear finetunes otherwise the new player
       |     |            | will play samples with stored finetunes.

       |     |            | Each sample name has 30 bytes ended with 0
       |     |            | You have 31 samples in module.

001572 | ... |            | Patterns.
       |     |            | 
       |     |            | 
       |     |            | 
       |     |            | Patterns can be packed and not packed 
       |     |            | Each not packed pattern takes 2048 bytes
       |     |            | So lenght of this hunk (all patterns) you can
       |     |            | calculate such like this: PatNum*2048 (easy?)
       |     |            | 
       |     |            | If the patterns are packed...
       |     |            | Each packed pattern at beginning has stored
       |     |            | its length[2]
       |     |            | Address of next pattern you can calculate in
       |     |            | this way:
       |     |            | - take a length of last packed pattern
       |     |            | - and add (2)
       |     |            | How to depack pattern read below

Packed pattern format:

offset |bytes| contents   | meaning
-------+-----+------------+-------------------------------------------------
000000 |   2 |            | Length of packed pattern[2]
-------+-----+------------+-------------------------------------------------
000002 |  64 |            | Pack table (stored as bits)
       |     |            | If bit is set you have to take a four bytes
       |     |            | (long word) from packed datas
       |     |            | IF bit is clean you have to clear four bytes.
       |     |            | That's all... (very easy?)

000066 | ... |            | Packed datas
-------+-----+------------+-------------------------------------------------

- Each depacked pattern has 64 positions, 8 tracks.
- Depacked pattern has following structure:

CHN1ADAT, CHN1BDAT, CHN2ADAT, CHN2BDAT,CHN3ADAT, CHN3BDAT, CHN4ADAT, CHN4BDAT
