MODE 4 Video Player

Postby kieranhj » Sun Jul 23, 2017 1:55 pm

Hey all,

Since I was busy hacking the old Bad Apple video player I thought I'd do a full screen MODE 4 test... completely unoptimised but fun & has potential. :)

Here's a linky if you don't want to download the DSD: https://bitshifters.github.io/jsbeeb/?disc=https://bitshifters.github.io/content/wip/mode4-video.dsd&autoboot&model=Master

Very impressive! (And thanks for the jsbeeb link, makes it super-convenient to look at!)

Thanks. I thought I'd run another test using ordered dithering to grey scale a colour video. Yeah, might be pushing the limits a bit trying to run this full screen!!

Thanks! And for old time's sake, although I don't think it would have been so successful like this!
