I used to be able to use the ZX Spectrum core on my PVM, and it was fantastic, but recently it won't sync on the screen, and I can't work out what has changed.

I've tried using:
- External sync using the H and V sync cables coupled into one using a T connector (this is the setup when it worked before)
- External sync using just the H sync cable
- External sync using just the V cable
- Internal sync using composite_sync = 0
- Internal sync using composite_sync = 1

Menu and other cores all look amazing on my PVM, but I just can't get the ZX Spectrum to work - it's annoying as it used to work perfectly!

It's the same issue on the Amiga core - both worked perfectly a few months ago.

Fixed.

It was a setting on the PVM needed tweaking. H Frequency.
