After looong break i'm looking again at Wheels & Fire from TCH. Game is running on custom, blitter based hardware (sprites + framebuffer layer with linescroll feature, and sprite-to-framebuffer rendering mode ). I have made a lot of changes/improvements lately, but there's still a lot to do: - proper image scaling - quite weird (close to hardware, i think) way to draw scaled images. for more details pls scroll down to the end of this post. - framebuffer (various problems) - sound - not emulated yet (2nd 68k + samples) Here's few pics from the game: W&F video hardware supports image scaling. For each image(sprite) to draw, there's a couple of parameters sent to the blitter: - screen cooridnates of image rectangle ( top left ad bottom right corners) _after_ scale transform applied, - source image cooridnates (only the upper-left corner, no info about the source dimensions), - two sets (for x and y scale) of magic parameters : da...
