I've looked at the code a bit more, fixed some misconceptions, and added some more of the code with comments. The drive head movement routine does indeed set the density for each track based on a simple 2 value lookup table. Density %10 for track 18, density %11 for all other tracks. There's also some weirdness at $03bd that might allude to what VMAXX posted earlier about the stepper motor wait time. Still can't get the game to load properly after fooling the checks though. It zips back to track 12 again and loads for a few seconds and crashes. Perhaps the sync values are sent back to the c64 and checked again. I haven't looked at the c64 side of the code at all yet. |
