new video mode...
Posted: Sun Oct 08, 2006 12:56 am
I saw some interesting things in recent demos, and wondered about a way to do similar stuff in text mode...
Came up with a funny text mode :
Basically, the first char of the line switches to HIRES, the 2nd byte of each HIRES line has a color attribute, then the 3rd has the text attribute to go back to text (an optional 4th one has a alt charset attribute)
I think it could be used with more colors / interleaved colors like RGBRGBRG and matching alt charset, this gives a virtual 8 colors 2pixels / char...
about 15 to 20 lines (more means charset colision) of 40*2=80 8 color pixels... not counting the video-inversion bit every 2 pixel.
Using text mode means less data to handle (= higher frame rate).
