Hello, the video game super chase has the intro not synchronized with the music unlike the original hardware where the intro and the music are synchronized.
Here the pcb for reference

edit: CPS1 games are reacting 1 frame later than in mame.

Hmmm, it used to be the other way around, right ? I'm wondering what happened

@dink: how u doing, I don?t know if you are aware of this in relation to the Shuma gorath raster effect from Marvel super heroes but as far as I know only one author got it right and did it correctly or shall I say accurately and that is the old nebula emulator from elsemi, you may want to look into it if your still interested in solving this old mystery for fbneo and I don?t think jotego ever got back to you about this either? I would?ve provided some screenshots but unfortunately my puter is fried..

I don't think nebula ever released its source code ? Or actually wasn't it supposed to have been incorporated in MAME ?
As for screenshots, i think we are good since we have pcb videos.
The answer probably is in https://github.com/jotego/jtcores/blob/master/cores/cps2/hdl/jtcps2_raster.v, but i don't understand much about vhdl language

the_maq,
Unfortunately I can't figure out how/where the top irq chunk is being scheduled, so its a mystery right now.  I'm not too worried about it, it's only the top several lines of the screen - everything else is bang-on.

That sucks about your computer, maybe it can be fixed?

best regards,
