GB sound emulation w/pascal

[phedon]

Hi,
I'm currently working on a tool (written in pascal), therefor I need to know how this works.
I have absolutly zero knowledge of sound programming (but I know how to code ).
Does anyone have informations for me about where to begin?
Gameboy emulation is declared as rather easy here at emutalk

Regards

phedon

edit
For now it's enough to output some tones/notes/sounds/instruments - no full music
For example:
Instrument data:
Type: Pulse
Envelope: 77
Wave: 50%
Length: FF
Sweep: FF
Hope this is helpful

hi,
first of all welcome to the forum.
And well firstly i assume you know how to playback samples in pascal and then you can have a look at this paper:

This sheet is very complete, the sound emulation of my gb i solely based on it.
If you have more specific questions how to exactly emulate it, feel free to post it here

edit:
woops sorry i didnt see your edit, gonna change my post accordingly later on when i got time

Hi WingsORC,
