Okay here are my research results, with links to my screen grabs of each example (note you will need to right-click on each image and select “View Image” to see full detail):

Sega Saturn NTSC Model 1 OSSC optimal timings:

320×224 (Game Example: World Heroes Perfect [has in-game letterboxing] )

Video in proc.:

Video LPF = 9MHz

Ouput: (for 240p/288p proc)

Make sure whatever linex you use is set to “320×240 opt.”

Sync opt.:

Analog sync LPF = 10MHz (I tend to base all my profiles on this setting)

Sampling opt. <Adv. timing > 320×240

H. samplerate = 427
H. active = 320

I didn’t have to change H. synclen or H. backporch as it happened to fall dead center on my capture card.

Sampling opt.:

Sampling phase = 225 degrees (this will differ from console to console).

352×224 (Game example: All of the various Capcom arcade fighting game ports)

Video in proc.:

Video LPF = 9MHz (vital for some saturn consoles in 352 and 704 res modes)

Ouput: (for 240p/288p proc)

Make sure whatever linex you use is set to “320×240 opt.”

Sync opt.:

Analog sync LPF = 10MHz (I tend to base all my profiles on this setting)

Sampling opt. <Adv. timing > 320×240

H. samplerate = 455
H. active = 352

I didn’t have to change H. synclen or H. backporch as it happened to fall dead center on my capture card.

Sampling opt.:

Sampling phase = 225 degrees (this will differ from console to console).

704x480i (Game example: Virtua Fighter 2 [stage areas] )

Video in proc.:

Video LPF = 9MHz (vital for some saturn consoles in 352 and 704 res modes)

Sync opt.:

Analog sync LPF = 10MHz (I tend to base all my profiles on this setting)

Sampling opt. <Adv. timing > 480i

H. samplerate = 910
H. synclen = 62
H. backporch = 98
H. active = 704

Sampling opt.:

Sampling phase = 225 degrees (this will differ from console to console).

Note the optimal timing couldn’t perfectly fine-tune the dot alignment. Some slight ghosting appears on hard edges.
