@sleve_mcdichael said in 1on1 PSX Background issues:

@adambegood just so I understand...the solution was "fix the code and recompile your emulator from source" or am I reading that wrong?

Yep, change Line 35 of the scriptmodule to BUILTIN_GPU=unai and then Update from Source. Let me know if you need more detail on how to do that, I am no pro but could just about manage this!

What exactly 'not working' means ? EmulationStation doesn't start ? Games aren't working ? Installation is not completing ?
Please add more details about your setup, including the Ubuntu version and hardware details.

As this question has not really been answered yet: for the people who bought a 4/8GB Pi4: as far as this amount will never be useful for the emulators, would it be helpful to increase the VRAM to 2/4GB?

@quicksilver
In buffered I get this, but I don't know how to change it in lr-ppsspp, but in ppsspp it gives me a black screen.

@BuZz Thank you. I made some edits to my post above to help prevent silliness. You are correct, it was psyke83 who suggested the change.

Your directions above worked perfectly, as expected and I reverted all of the configuration changes. And scummVM also works as expected.

Thank you for the commit, and for letting us play in your house while you and the team tidy-up the inevitable release.

I had the same issue. The problem is that RetroPie manage default resolution very bad.
To solve this and other performance issues just play with the resolution and set the best that fits your needs.
You have to enter the raspbi-config -> display options.
If the system crashes when you select display options, use this trick:
Enter the menu and before opening display options disconnect the HDMI.
Than open display options (with screen off) and connect HDMI again.
It should solve the problem.

After I changed resolution I experienced a big performance jump!
And all that glitches and sprite problems was solved

@cagusch Have you tried it on lr-duckstation?

Also, not saying that that's the case, but it is quite normal for games to reduce polygon count and drawing distance when rendering split screen. What's the atual behavior you're observing?

IT WAS THE ROM DUMP!!!!!!! I TRIED THE SAME ROM ON MY PHONE AND ALL THE GLITHCHES ARE THERE!!!!!

@dankcushions

Ok thanks

This is a CRT via composite: Brightness about 40

And this one with Brightness: 25

Problem is, this is a really low Brightness, even if I bump Contrast to ~80. There's one more variable in my telly (S-Bright), but overall I play with the brighter version on. It all depends on a game though: for example in this title (CAW) the low brightness is mostly fine, but in other, darker titles you will start losing details. It's also dead hard to calibrate properly, I'm not even sure if its possible, to have one profile for all games and systems.

@dankcushions yeah, it's probably as simple as that. I just wish there were some way to fix the issues.

I have similar problem. I thought its my adapter to the monitor. I use a dongle for keyboard too. What was the interval when you got this screen freeze? I get it maybe once in a hour. Maybe its a different story on my side.

@BuZz I just saw that Libretro-Mupen works fine without Problems, and i love Retroarch, so im gonna use that Emulator from now on!

@osiviper great to hear. Enjoy!
