This disc image contains tunes composed by a musician of the Atari ST demo
scene (Big Alec of Delta Force) which have been transfered onto the Amstrad CPC.
The Amstrad CPC and Atari ST have compatible sound chips which made the transfer
easier.

Transfer procedure:
1. The drivers were ripped on an ST (using a Ultimate Ripper). 
2. The files were were then copied to the Amstrad CPC, 
3. I disassembled the driver using a Amstrad BASIC program I wrote (disassembles 68000 code)
4. I then converted each instruction step-by-step into equivalent Z80 assembly instructions.
5. The final sound can then be played on the Amstrad CPC.

Run "bigalec.bas" then select a .mus file (type the filename and extension).
The music should start and you can then listen to it. The coloured block indicates
the time between interrupts. The moving coloured region indicates the time the driver
uses to generate the instructions for the Amstrad CPC sound chip.

These tunes were transfered around 1990.
