I doubt that there is a way to have a fully OS compatible player as timer C is the system timer but timer D is also used for RS232 comunications.
Of course you can say who cares about RS232 and you would be right at this stage.
A timer will always be required for BPM as you can see in the Amiga reference Protracker 2.x source (look for CIA programming).


By the way in my source you can see a use of the timer B in Event Count mode but only in PAL mode.
The idea is to have a precise "VBL" trigger at the end of line 200.
That interrupt has much more priority than the normal VBL and so the DMA data refresh is made more accurate.
You can scrap that and move it always to the VBL but you may loose some quality.

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
