Horrible hack of the VMW chiptune player code to try to play a 6-channel file.
|
|
|
|
There's really not enough RAM to do things this way.
|
|
|
|
Proper solution is to write a real pt3 tracker.
|
|
|
|
|
|
|
|
Hacks:
|
|
Needs 10k+10k RAM for each KRW file (converted PT3)
|
|
Needs 14k+14k for buffers
|
|
Needs 4k for player
|
|
==================
|
|
52k RAM, more than we have on stock Apple II
|
|
|
|
We cheat and use language card which gives up 64k in theory.
|
|
|
|
The problem is we use interrupts, and the interrupt routine is
|
|
hard-coded to jump into the $F000 range. IIe/IIc might
|
|
be smart enough to handle this, but older machines are not.
|
|
|
|
Hack: copy the FXXX range into the language card so it doesn't
|
|
matter?
