OSSC Optimal Timings for PS1

Post by Tobiasrieper » September 30th, 2019, 6:37 pm

I just invested an OSSC and am knee deep in timings and such. It's such a great little device. My Dreamcast looks absolutely amazing with FirebrandXs settings.

I'm messing around with settings for my PS1 and just wondered what others users here used for their optimal settings?
I have mine on Line X5 mode for 320x240
and Line X2 (Bob) mode for games that run in 512x240. I get a much improved picture over just plugging directly in to my telly.

I had a look on FBXs page but couldn't find an entry for the PS1.

There is a Wiki page that shows some examples. You'll have to use Google to find it.

Hi Matt,
I've tested the settings from the wiki page and I'm just having trouble with the 480i settings. Spent hours over the weekend tinkering with it. Hoping someone here can share their 'recipe'

Iv'e got best quality using old 21' CRT Monitor SUN using Hdmi to VGA adapter TENDAK



about LCD, some models got problems with lineX5 like newest Samsungs, other like chinesse TLC work flaweslly :)
try use Luma on Sync cable :)

on my old samsung LCD 40' need do some settings to see PAL PSX games on Line3x (x4, x5 dont work)
PSX SCPH-7502 + PSIO + OSSC with Sun X7146A = amazing !

Heya buddy! Awesome, thanks so much for the link. I'll put those settings in after work. Do you prefer super sharp X5 or a lower line multiplication mode? Wish I got one of these years ago! The games look as good as I remember them . Been playing Vagrant Story, looks incredible.

Thanks so much for these, 320x240 looks even sharper now (almost emulator sharp!) and works properly at all multipliers. It got rid of the slight shaking I had at 3x too.

If you guys check out this thread on VGP there is a really cool web app you can use for your OSSC. You can tinker with the settings online then download them to micro SD and upload them to your OSSC

:) enjoy your PS1 experience.

I tried these timings with my SCPH-1002 PS1 last night and because of changing the "Line2x/3x/4x/5x/ mode: 320x240 optim." It made things look a lot worse than the setting I already had so I reverted that back.

It will depend on the resolution of the game you're playing, which is why there's 3 profiles for the most common PS1 resolutions. 320x240 optimised would definitely look worse on a 512x240 game for example, so you'd need to load the most appropriate profile on a per game basis. When correct it should be an improvement on generic 4:3 for PS1, at least in my experience.

I tend to use a PS1 debug emulator to find out the resolution of the game I'm playing, or you can just load all 3 and see which looks better.
