| Summary | 02534: djboy: [possible] Graphics glitch with the briefcase at the beginning of the 2nd level | ||||
| Description | Near the beginning of level 2, an enemy throws briefcases at you. The briefcase graphic occasionally flickers on then off for a frame or 2 in places that it shouldn't. I don't know if it's a bug in the real game or not. Also there may be other places where this happens with other graphics. I attached an inp that will take you through this level. | ||||

Made snaps from the INP - one when the case appears in the wrong place, then again after it shows where is should. |

it's an interrupt timing issue I think, the driver currently toggles 2 interrupts with even spacing when in reality they should probably relate to specific points in the screen (vblank in/out maybe) this causes the spritelist to be updated at the wrong point, and the glitches to occur. If you simply swap them over you get very jerky video update instead. it could of course happen to an extent on the real PCB, as it does on B.Rap Boys, but still, the current interrupt timing is a hack. |

Very brief appearance of the suitcase out of place in the arcade pcb too: 8:42 |
