I get quite heavy graphical glitching on the starfield during gameplay on an A1200/PAL/TF1260/WB + KS 3.2. It has also got stuck in attract mode with the "tractor beam" sound effect looping.

if you have glitches, I'd advise to turn off stars scroll. This is probably a sync problem between display and "scrolling".

High-score is always 0, but I see a high-score file in the folder? Real hardware. Amiga 4000.

yes, after 7 minutes, it looks very bad.
for me something is not cleared, but maybe this is other bug. |

this is a hardware sprite bug. I also have this on my A1200 after a while. Strange as the code does exactly the same all the time. DMA interaction with something else probably.

Is there something like audio buffers? I know I am way out there but the sound is also distorted. |

For me it looks like accumulated code bug. Exactly trashed data or trashed register(s), f.e via movem.w instruction. You can try to call Stage 4 as first stage, and check if graphical glitches occured. Edit. First time when I see graphical glitches is after ship was captured and recaptured (about 1 minutes 35 secs). Exactly before Stage 2 was started. Then can be init Stage bug too. You can check without ship capturing too. Last edited by Don_Adan; 27 July 2024 at 15:09. |

Ok, now I'm lost as it works fine on WinUAE. Not a single glitch. But on real hardware the glitches are there. You'll have to wait until I can test on real hardware. It may take a while as I'm away from home.
I zoned one last version, as the gfx corruption passed undetected but it shouldn't have been. Wrong bplmod but winuae displays it fine. |
