The sprites in BIGTWO are only 42 lines high, because that way one animation frame fits into one 256 bytes page. Not crossing a page boundary is important for the timing in the display routine. Having 100 animation frames is a bit much for the VCS too. The best(*) cartridge format for a game like this is IMHO the 32 kb format with 3F bankswitching. Spending 25 kb on animations alone wouldn't leave you enough room for the game code, I think. (*) That is until Chris finishes his Megacart of course. ;-) >(400%) at the far right. Comparing with the original, it's reasonably OK - >certainly good enough for a frame of animation in a constantly moving >fighting game. I plan to do a dozen or so frames, just to see how they'd The results look a bit chunky. I think you would need to manually edit at least the end frames of the animations, since they would be visible for a longer time. What you also should take into account is that NTSC TVs have a different resolution than PAL TVs. While on PAL the pixels are almost squares like in your graphics, they are higher than wide on NTSC which would make your graphics look vertically stretched. >look. If there's any interest, I will post the results for stella readers >to examine. I would be interested, mainly because I'm too lazy to draw all those animation frames for my fighting game myself and I'm hoping to be allowed to use your graphics. ;-) I have programmed a little converting program for VCS sprites, that takes PCX graphics with a resolution of 320*200*256. Colours between 0 and 127 are treated a pixels and colours between 128 and 255 are treated as background. If you post your graphics in that format with every animation frame taking 48*42 pixels starting from the top left corner, I could put them into my fighting game kernel and you could see if your graphics would work as animations.
