Thanks for all of your hard work!, looking forward to fine-tuning my Mega Drive and experimenting with the new scan-line modes.

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.

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.

What kind of component cables do you have? I also have a PAL console (SCPH-39002) and with the OEM PS3 component cables there are no ringing artifacts and no noticeable noise at a reasonable viewing distance. That said I do not play any PAL games and instead stick with US/JP releases.

While we’re all talking PS2 does anyone here have any experience with optimal timings for PS2 games?, I’ve had some success with the games listed at junkerhq but is there any easy way to determine the internal resolution on a PS2 game?, for PS1 titles I’ve been using PSXemulator’s debug function to grab the internal resolution so I can set the optimal timing mode accordingly.

It’s me again guys!,

Just looking for some help with PS1 Optimal timings; through 240p test suite I have been able to get some pretty good results on my KDLx8500c with 340×240 (line 4x), 384×240 (line 4x) and 256×240 (line 5x). I have been using the optimal timings found at Junkerhq however, I can’t for the life of me get 512×240 to output a clean picture, no amount of sample phase adjustment or H samplerate tinkering seems to be able to clear up the noisy vertical bars in the picture.

Anyway I’d really appreciate some help as I wasted quite a few hours getting nowhere this afternoon.

The games are running through my PS2 via OEM component cables, but I can try my RGC RGB cable if anyone thinks it would help.

So, it turns out I made a few rookie errors in the web app while planning my profiles that I didn’t catch until now. Now everything looks great at 512×240 at line 4x!, however the aspect ratio is 8:7 is there a way to correct this to 4:3?, my 8500c doesn’t really have any scaling options other than to scale proportionally to height or force 16:9.

@Harrumph

Thanks for your explanation, that more or less clears up why 5x works without issue on 240 optim on my set but 320 causes so many issues. As I said earlier I really lucked out with my 8500c since it has no problems with 2x and 4x so I shouldn’t be too discouraged by the issues with 5x for my Megadrive.

[Listai]

No luck unfortunately.

Even with generic 4:3 mode on I can’t get a picture on 1600×1200 or 1920×1080. Oddly 320×240 at 1920×1200 is the only one that seems to work in that generic mode. I think I’ll call it a day until I get my RGB bypass installed.

While I’m a little disappointed my Sony kd55x8500c has been fairly forgiving with what the OSSC throws at it, considering it was a blind buy on sale well before I picked up my unit.

[Listai]

Thanks for getting back to me so quickly.

I think I did try 1600×1200 but I’ll go back and check at 427-428.

The only other thing I noticed that with my TV the analog sync LPF seems to cause more problems than leaving it off. For both my Super Famicom and Genesis I’m able to get clean pixels with no ringing or ghosting with the LPF set to off, I have to adjust the horizontal position but after that and a quick samplephase tweak it has less noise than when the LPF is enabled.

I’ve ordered a RBG bypass board and I’m crossing my fingers that it might help solve the problem I’ve been having with 5x.

Thanks for your assistance, I took another run at it this morning but ran into the same issues.

I can only get an image to display in 320×240 optim by bringing H. Samplerate back to around 423, but there are four large vertical bars of noise that only duplicate and grow closer together when I experiment with different numbers. Generic 4:3 brings up an image immediately and only required a small tweak to sampling phase to bring everything into line.

I should be happy with 4x mode, but the image looks so soft on my panel compared to my Super Famicom at 5x.

[Listai]

I’m having a similar issue with my Megadrive, my TV can display up to 5x on 256×240 titles with no issues whatsoever, but with 320×240 games I can only get the optimised mode to display up to 4x. However the image does display at 5x when I select generic 4:3.

I’m running a Japanese model 1 Megadrive with Retrogamingcables uk’s Scart cable on a Sony kd55x8500c and as it is a 4k panel I run 5x in 1200 line mode. My Super Famicom also has no issues running at 5x mode.

I was able to get an incredibly noisy image by changing H.Samplephase to around 427-ish but I never could get rid of the noise. I’m a bit of an amateur so some tips would be appreciated.

[Listai]

Thank you!,

That will teach me for skimming through the wiki instead of reading it.

Works perfectly now.
