I presume that's done INSIDE the VIDEO_UPDATE then, even though I've said to death to not do it here --"

I'd like to quote video/dc.c, because it's basically the same thing for this case:


MAME note

The video update function should NOT be generating interrupts, setting timers or doing _anything_ the game might be able to detect
as it will be called at different times depending on frameskip etc.

can anyone else reproduce problems in SMK (J)?

Tried many times ... probably you have something like OPTIMIZE=0 in makefile or dunno, it gives black screen specifically on my end for whatever reason ...
It remembers me a similar bug on Prikura Daisakusen for the ST-V back in the day ... I was getting correct graphics but Haze was getting just garbage ... turned out that I wasn't returning proper values on a DMA status bit ...

Practice makes perfect, that's the secret of VGs ... I suck at puzzle games and 1vs1 2d beat'em ups, but mainly because I don't play these at all.
