Experiments in Linear Screen Modes

Post by kieranhj » Fri Jul 21, 2017 7:58 pm

Hey all,

I got a bit side-tracked from the scanline-timed raster effects with all this talk of the linear screen modes (esp. MODE8L as I will now call it.) I realised that there was a quick & dirty hack I could do with the Bad Apple video player to make it full colour...

It's in the wrong aspect ratio etc. but quite a nice result I thought. Shame there's nowhere near enough bandwidth for digitised audio as well!

Let me know what you think... I'll keep posting any other prototypes I come up with.

PS. Here's a link if you don't want to download the DSD: https://bitshifters.github.io/jsbeeb/?d ... del=Master

:shock: Wow! I never thought I'd be able to sit back and watch colour digitised video on the beeb! =D>

How many discs for the whole film? :mrgreen:

Great work Kieran.

There are some very impressive sampled audio tracks on the beeb that seem to be very compressed.
I was wondering if the audio playback code was interleaved with the video code whether it would be possible to play audio through a D2A (resister ladder) on the printer port.
