TM>I'm not sure I understand... what do you mean by 2 char lines? is this

 Yeah, every 16 rasters (or 2 char rows). He changes fonts, multicol modes,
ecm modes, back/forground colours etc. Allows him to have logos in the text
(using a font in multicol mode), plus anything else like diagrams, or just
have text in different size fonts etc.

 TM>Tell me more! What channels are you using, what sort of raster time is
 TM>it taking up, etc...
 
 It just uses the $d415 volume register, but the NMI interupt 'adds' the
two samples in real time. It can also play either channel at different
speeds, ie the samples caÿûn be played at different pitches. The raster
time only allows 2 digi channels this way, so I was hoping to add 2 SID
channels as well to make it a 4 track player.

 TM>A SID player is basically in two parts - the part that handles the

 TM>adjust the registers. That's all pretty straightforword. The more
 TM>complex stuff involves special effects like ; pulse waving, vibrato,
 TM>filter waving, arpeggios etc.
 
 Yeah, I understand the first bit, bit getting decent sounds escapes me. I
think most players change waveform in the middle of the sound to create
different waveforms & sounds.

 TM>Ideas are being thrown around... like : a replacement ROM for the 64
 TM>similiar to Jiffy DOS. As the routine is pretty small, it may be
 TM>possible to trim it down so it can fit into the cassette buffer, and
 TM>the cartridge is another option...
 
 I think a replacement rom is the way to go, or possibly a cartridge that
on every reset shoves the driver in memory & then boots the normal 64
rom.
