Keep an eye on https://www.youtube.com/user/KarbuncleX/videos – I think he’s going through and doing optimal timings for all consoles, and the Saturn will be soon. This is FirebrandX btw, the guy who did the well-known profiles for the FM.
From my conversations with the guy on the OSSC/FM facebook group, what Harrumph is saying is correct – the Saturn has two output modes, which will both need different h samplerates. The 427 value on the optimal timings page works for some of my games (Sonic Jam, for example) whereas it’s totally out for something like NiGHTS. I also wish there was a 240p test suite 😛
