Hi there! Thanks for fixing the binary Dennis!

More or less it's an experimental something binary :-) There's lots of technical issues to solve and I'm just starting. I was just posting binaries and the source to document the process and maybe get input and advice here or there. Basically the display is now composed of 8 2LK resolution stripes, which do: - 2 lines repositioning a ship with a battlezonesque technique. - 2 lines kicking in the display for a moving 6 char like display - 22 lines of sprite display At least that is ~ the plan. There's lots of technical issues still to solve. One of the major points is to have the torpedos smoothly crossing any lines of these three types... An other issue is finding a way to move the range where the battlezone trick works smoothely, from pixel 0 to pixel 144 (160-16). I also had this weird idea of a small chance existing where the timing required to repostition may also already be able to control the delay required for kicking in the moving 6-char code... You'll see, the major factor for this to work is probably unsolvable, as the repositioning requires a precise HMOVE strobing, which'll normally require a WSYNC, which'll ruin the timing for the 6-char and the cat is biting it's tail... :-) Well, to sum it up, I yet don't know wether 24 pixel wide sprites will work good enough in the end or not...
