Recently, ( see sp manbow2 ) it was proved that a limited horizontal scroll is possible also on screen 5 at the following conditions:
-draw a part of the screen on a hidden page after using r18 to fine-scroll horizontally.
-do not draw unchanging tiles between frames.
I've done some experiment and the horizontal scroll could reach 65 fps at 60hz on a 28*20 char area in sc5.
It's possible to modify the vscreen engine and make it working in screen5 ?
Everything is always possible but I think writing a new engine screen 5 based (like the one of Total Parody) would make more sense... VScreen is very much based on the idea of a tile based screen mode. A V9990 port would be much easier than a Screen 5 port...
Writing a new sc5 engine is possible of course, but I would not be interested in doing such thing myself. You would be very limited regarding how fast you can scroll, perhaps one or two pixel at a time. Not exactly ideal when you want to make a fast action game...
Last version is still 1.0. I made a few changes to the code to be able to compile on the PC using a cross assembler and have a few ideas for improvements but right now, I barely have the time to even turn on my MSX.
Hi! I'm looking for that VSCREEN, I've tried a lot of searches and links but it didn't seem to be on the net... I've found some demos but not the engine... is it available?
