another video demo

It looks like it's not advancing the audio clip counter / frame counter and just repeating the same audio clip over and over.

I think you're right about the video but the audio might be ok; the first several seconds of the video sound like that, and the audio isn't triggered the same way as video.  

Has anyone who downloaded this tried it on the emulator?

[ZeroByte]

I've run it on the emulator just fine.

Can't recall whether it was using SD card image or host FS though. (that makes a huge difference)

Ok, that helps narrow it down, then, it wasn't a problem with the upload. @Wavicle is the BOND folder and BOND.PRG in the root directory of the SD card?

Another possibility is that the hardware is still slightly slower than the emulator, and perhaps only 12 fps is possible. But then that would show just the left side of the image changing...

Looks like moving the files to the root was one thing that needed to get fixed. Now it only updates the left side of the display as you'd mentioned it would do if it couldn't keep up.

I'm going to try again soon, using @ZeroByte's suggestion of using MACPTR. That will get the number of files down to 3 - a PRG and two SEQs - and perhaps I'll also lower the video frame rate to 12 fps.

The sound seems to work, except loading the audio into low RAM and then pushing it to VERA is taking too long and it occasionally runs our of PCM data, hence the pops. Hopefully MACPTR  fixes that too.

One other thing that I forgot to mention and just tested - the demo appears to depend on memory being cleared to zero, which it isn't on hardware. @MooingLemur wrote me a raminit program that clears memory and when I run it before bond.prg, the audio is a little bit better (the video is still stuck though).

I suppose I should share the code I used to make this. No, it doesn't depend on anything being set to zero, except for the one tile that is used in the top two and bottom two rows on the screen (it's 8 rows by 20 columns).

Are you using an actual VERA?

Yep, I have a real VERA. The rest of my hardware is compatible of my own design, but my VERA is a VERA.
