Reply To: Question about SNES sync drop

[nullifer]

I’m pretty sure this SNES is one of the earlier releases.
It says 1991 on it, it’s very yellow, and Final Fantasy Mystic Quest debug says
cpu ver.1
ppu1 ver.1
ppu2 ver.1
I have a pretty cheap Scart cable, I have no clue which sync it’s using. I plan on getting a packapunch csync soon enough.

I’ve seen other threads talking about adjust H-pll pre and post, and some others talking about vth might help out.
I’d like to know what they actually do, help/hurt
