[Coco] RG6 video playback test

[James Ross]

That is as cool as heck!!  Simply amazing Ed.  

Sorry if this has been asked and answered already, are you using tricks that are specific to the CoCoSDC, to be able to do this?

Hi Brendan,

It’s using raw data (pre-rendered), without any decoding, in a precisely timed
sector read routine.  It requires only the video pages used (one at the moment)
and a small 512 byte buffer for audio, outside of the player code itself of course.

An optimal sector interleave format is required, but in this way, complexity of the
image and file length do not matter.  Up to 3+ hours of continuous playback anyway,
due to max file size.

Right now there’s no screen buffering, so there’s some “tearing” when there’s large
changes between frames (actually seeing the bytes being placed in video ram).
Next I’ll implement screen buffering to eliminate that.
