Yay! Great fix Been waiting for that for a long-time. I think I actually understand the fix in the VICE-repository as wellgroepaz wrote:ok, so as for the rasterline 0 "delay"... i fixed it in r29805 - "capture the flag" works perfectly now (and also, as far as i can see, all the other games listed as "ntsc only" in megacart).
Se attached to this post below. It's a simple-basic-program that utilizes a small machine-code-raster-routine. I fixed up the program in the last two days a little so that it can work with interlace as well. Strangely enough, value 0 in $9004 flickers in interlace between position 0 and 33 and does so even when I add an extra waiting loop that waits for raster-value 131 just beforehand (which only appears in every odd field). Really strange...it would be great if you could also post the source to that test program, so i can include it in the VICE repo
as for the interlace thing... a test program would be really nice, too
Great idea! But sadly when I drop this into a fully expanded VICE (latest r29805) it crashes after a secondedit: just for fun, last nites hack: Capture the Flag for PAL
