| Summary | 06945: Timing issues in Jumping Jack'son | ||||
| Description | The latest slave has definite timing issues. Please see the following videos. I've confirmed this on WinUAE, but I seem to recall it happening on MiSTer as well. WinUAE config: AGA, 68020, 24-bit addressing, Approx. A500/A1200 speed, 68882 FPU, Cycle-Exact (Full + DMA), Full Collision Level, Wait For Blitter, Kickstart 3.1, 2mb Chip + 8mb Fast Video 1: https://streamable.com/arxzvd - raster bar issues on level screen, followed by in-game being very slow. Video 2: https://streamable.com/6mf5xo - game froze, but whenever I opened WinUAE's menu, then exited, it would advance 1 frame (you see my mouse cursor appear each time I did this). And I've seen other timing issues with the animation later (I think when you completed the bonus stage?) I played this game extensively back in the day and I can say with certainty that there's a lot wrong here, unfortunately :( | ||||
| Steps To Reproduce | I'm not sure if this is a 68020 issue or not, but I suppose try my config listed above to confirm. | ||||
