Got the NTSC-J Saturn and all is well now. Glorious 5x 🙂

Thanks again, and merry christmas!

A second crystal? Not sure what you mean 🙂

Thanks for your efforts again, Steo. An opportunity presented itself and I snagged a NTSC-J Saturn for 30 Euros. I hope to get it in the next couple of days. Hope that’ll work better 🙂

Forced 16:9 2x sounds nasty. Already left home so no ability to tinker for the next couple of weeks but I haven’t had any luck with 3x using the settings in the guide we talked about. You can imagine my surprise when 3x wouldn’t work but 4x would, although with funky aspect ratio and wobbly pixels.

I thought so. I wont be able to test your latest suggestions until I return from a business trip in a couple of weeks. I think I will run with the setup as is for now and maybe revisit getting a NTSC variant in 2019. After all, I’m off much better than than I was when I created the thread.

Thanks again!

Steo, thanks again for all your efforts. I should’ve mentioned that I had the TV already set to Computer mode. When running the DC or Wii in 2x, it would show 960p as PC mode. With your comments towards PAL limitations it seems that a NTSC Saturn would’ve been a better idea? I was thinking of modding it to to 60Hz, but according to the JunkerHQ Wiki, that’s not going to work well with the OSSC either. Maybe I should flip my Saturn for a Japanese one, they can be had fairly cheap.

My TV is a Philips 43PUS6551, the Saturn is a Model 1 PAL. I didn’t notice this issue previously, maybe it wasn’t that obvious with 2x. It’s not limited to Sega Rally though, I’m seeing the same with Castlevania Symphony.

Thanks again, Steo. I’ll get back to tinkering and report back with my findings.

Edit: Here’s what I found with the Saturn:

1. Increase H. Samplerate to 2200 and H. Active to 1920.
2. Decrease V.Active to 270.
3. Increase V.Backporch until you get picture (approximately 28).

TV says no.

Alternatively, if you cannot force 4:3 you can attempt a Lx4 1440×1080 50Hz 4:3 image: increase H.Samplerate to 1900, H.Active to 1440, h.sync 150, h.backporc 212.

TV says no.

If aspect ratio still looks off, try H.Samplerate 2460, with both H.Sync and H.Backporch around 215.

TV says yes!

But aspect ratio is totally botched. It’s near fullscreen on my 16:9 TV, and I haven’t found any way to force 4:3 on the TV. I have plenty of image options (stretch, fill, manual zoom, original) but no 4:3. The manual doesn’t mention it either. Plus, the pixels are somewhat … wobbly or shaky? I don’t know how to describe it better, English is not my native language, sorry.

Here’s a quick clip, hope this helps explain what I mean: https://youtu.be/Dsx-kzYbNd8

BuckoA51 and Steo,

many thanks for taking the time to reply!

Support for PC resolutions (i.e anything other than 2x or 5x 1080p) at 50hz PAL are rare. No PC ever output these resolutions at 50hz you see. Most TVs/monitors will reject this. I think some of the ABT scalers support it (Edge, but maybe not VP50/Pro) but yeah, not very common at all.

Hmm, should’ve gotten a NTSC Saturn then, I guess? I’ve been tinkering some more and managed to get 2x from the Wii using VESA 640×480@60. DTV480 would suddenly work as well, but crops the right side of the image. Why I managed to get it working right after posting here is beyond me, but maybe this will help someone else with the same problem.

For the likes of Saturn, you might get 720p50 working with tweaks but you’ll be cropping a lot of the picture vertically. This might not matter for some games with black borders.

There’s also a tweak I talked about that gets you 4x 1080p50, but that might only work if you already get a picture at 5x with the OSSC set to 1080p. I prefer the 4x method for PAL since you don’t lose a lot of vertical detail that way.

I was previously limited to 4x with the Neo Geo but more tinkering today enabled me to go to 5x with 5x set to 1600×1200. I’d be happy with 4x with the Saturn, if only I could achieve it. Care to elaborate on the tweaks you mentioned? 🙂
