Same issue as Sky Adventure having a misplaced explosion when dying + other side effects cfr. https://github.com/mamedev/mame/blob/master/src/mame/video/snk68_spr.cpp#L34 Inner workings of the sprite DMA aren't known, given the structure I suspect a pretty consistant delay and possibly async operations between each group. |
