Culture Brain titles graphic glitch with analogue IO

[xenyou]

It seems that some of Culture Brain titles have a graphic glitch with analogue IO board.

The titles I checked are:

• SD Hiryuu no Ken (Japan)
• Super Chinese World (Japan)
• Super Chinese World2 (Japan)
• Super Chinese Fighter (Japan)

Only audio is fine. But the graphic is flickering and I can't play it.
It's also reproducible with HDMI and DAC (direct_video=1).

It might be fine with CRT display. I'm using LCD monitor (15khz supported).

Cute bird.

Have you reset the core settings to default to see if the problem goes away?

I've tried it. But it won't work.

And, I found this title is also reproducible.

• Super Ultra Baseball 2 (Japan)
