Extracted and edited music generating code fragment from a game "SOLDAT.BIN".
I love music from this game, but the game inner timer don't let to listen it for long.
So I decided to find a piece of code that is responded for music playback, then extract and correct it for the next execution.
With a help of the 'PDPy11' - a compiler for PDP-11 by imachug (https://github.com/imachug/PDPy11) this task goes much easier.
Attached test.bin file can be executed on BK-0010-01 emulator.
