Nintendo Arcade Cores not syncing on Arcade CRT after update

Unread post by 80sArcadeKid »

Has something changed regarding sync on some arcade and console cores?

MiSTer FPGA sync problems after latest update on:
- Nintendo PCBs
- Genisis, SNES, etc.
Neo Geo is fine, other arcade cores fine.

What is your vsync_adjust set to?

I'm using the default ini from the MiSTer repro with composite sync on:
composite_sync=1
vsync_adjust=0

I'm using the i/O board VGA out into a JPAC. These cores have been fine previously.

I did try vsync_adjust=1 but seem to make no difference, I could try 2 I guess?

OK.. weird as I;ve always had to use composite sync before but setting it to 0 fixed it.
composite_sync=0

Definitely try vsync_adjust=2 anyway, as it gives you the lowest display latency.

vsync_adjust is for the scaler, it's irrelevant if you are using direct/analog output, which is typically how people connect 15khz displays.

Oops. I could have sworn I saw a difference (such as it not working) when I used the wrong setting.
