PS1 Optimal Timing

[Frostheart]

Good evening,

I’ve been setting up retro consoles with optimal timing setting with my ossc after watching firebrandx’s videos. For the sega genesis, after setting optimal timing for 320 and 256 resolution modes, I used his list of 320 vs 256 roms to properly organize my files on an everdrive.

I plan on setting up setting profiles for my playstation 1. I read on junker hq’s optimal timings for various systems. I noticed that the playstation 1 has 4 different resolution modes. Junker hq provides examples of games for each resolution.

My questions is, is there a list similar to the one made by firebrandx for the sega genesis, specifying which games output at which resolutions. I know this may sounds like a stupid question, is there a way through the ossc, to see which resolution is being output to the ossc?

Thanks,
Frosty

FirebrandX doesn’t have any PS1 settings but the settings I use ain’t that bad tbh

320×240

-Output Options
   Line2x/3x/4x/5x/ mode: 320x240 optim.
-Sampling Options
   Sampling phase: 90 deg
 -Advanced Timing
   -H. Samplerate: 427
   -H. synclen: 30
   -H. backporch: 54
   -H. active: 320
   -V. synclen: 3
   -V. backporch: 15
   -V. active: 240

256×240

-Output Options
   Line2x/3x/4x/5x/ mode: 256x240 optim.
-Sampling Options
   Sampling phase: 11 deg
 -Advanced Timing
   -H. Samplerate: 341
   -H. synclen: 25
   -H. backporch: 41
   -H. active: 256
   -V. synclen: 3
   -V. backporch: 17
   -V. active: 240

512×240

-Output Options
   Line2x/3x/4x/5x/ mode: 512x240 optim.
-Sampling Options
   Sampling phase: 90 deg
 -Advanced Timing
   -H. Samplerate: 683
   -H. synclen: 50
   -H. backporch: 78
   -H. active: 512
   -V. synclen: 3
   -V. backporch: 14
   -V. active: 240

You may have to tweak these settings for it to be just right. Hope it helps!

Thanks for the settings, I’ve already saved optimal timing settings from junkerhq. I’ll double check my settings and see if yours work better.

My questions wasn’t about what setting to use though. It was, is there a list of what games output at what resolutions.

Thanks,
Frosty

Oh my bad lol

I don’t think there’s a list but most 3d games run at 512×240, a lot of 2d games run at 320 but there’s probably some 3d games that run at 320, Doom and SOTN (in-game) run at 256 pixels wide.

What I’d do is save a profile for each resolution and once you get your settings dialed in just load each profile while you’re in-game and see which one looks the best. That’s what I do.

Hey, thanks for sharing!

Do you know if your settings are also good for PS through PS2 – via back compatibility – or if it’s better to use a proper PlayStation?

Thanks in advance. ^_-

[ENunn]

It should work fine on PS2 aswell.

[Listai]

Yeah, my current set up for PS1 is just PS2 over RGB and it works great with the JunkherHQ settings. I use psxemulator’s debug window to get the main gameplay resolution for a game and then I note that down for each title in a spreadsheet.

[Galdelico]

@ENunn Thanks! I’ll definitely give your profiles a shot as soon as the new official fw lands.

[Frostheart]

@listai Never thought about this route, that would quickly solve most of my issues. Do you mind me asking what emulator you use?

Thanks,
Frosty

[Listai]

Not at all!, its easy to miss in my post but the emulator is actually called pSXemulator. The website seems to be down at the moment but the latest version is v1.13 the reason I use it is the debug window very clearly states the internal resolution at all times unlike other emulators.

I haven’t even bothered to properly configure it, I just button mash until I get in-game, update my spreadsheet and continue on.

[Frostheart]

@Listai Deadly! Thanks a lot for that.

Hi @listai I was trying to figure out the main game play resolution for a game using “psxemulator”. I got the game to load but I can’t find the debug window you described to find the resolution for the game? Can you let me know what I have to do to find this? Thank you very much.

Your settings (with a few tweaks) work great for me @Enunn, thanks for sharing.

@Enunn Thanks for sharing these and sorry to resurrect this thread from last year, but was wondering if you had timings for the another popular PS1 resolution 384×240, trying to play Ape Escape and i just cant get it right.

[ENunn]

No biggie. I do have 384 timings!
384×240

-Output Options
   Line2x/3x/4x/5x/ mode: 384x240 optim.
-Sampling Options
   Sampling phase: 225 deg
 -Advanced Timing
   -H. Samplerate/s.rate adj: 487.85
   -H. synclen: 37
   -H. backporch: 46
   -H. active: 384
   -V. synclen: 3
   -V. backporch: 14
   -V. active: 240

Tweak as necessary. I do suggest checking out FireBrandX’s profiles though. Since this thread was made FBX made PS1 profiles + the usual OSSC changes because of firmware.
