Yes of course, I'm not saying it's useless code. I'm just saying that it's useless code for my specific use :)

Btw when you developed this, did you use real hardware or an emulator? Some modules does not sound the same on a real STE as on Hatari, there is a problem with volume settings. I can hear that volume is set only occasionally, and usually only on one channel. I added a couple of lines of code to change the background colour when the timer C code is running, and I can see that it runs just as often as on Hatari. Maybe there's a timing problem when writing to the LMC registers. If I comment out the instructions that writes to the LMC the modules sounds identical on Hatari and the real thing.

Btw a side effect of changing the background colour when running the timer C handler is that I can see how much CPU it's using. Not very much, usually less than one scanline. So for an amateur demo/games-"coder" like me this means that I can use screensplits with reasonable CPU-usage without moving the volume/bpm-stuff to the VBL :) So I will not spend much time on this, atleast not until I have to.

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.
