@stoo While I haven't been able to replicate the weird performance problem I was getting before, I see why OpenGL is failing intermittently.

Seemingly at random when switching AA values, a shader fails to compile. It doesn't happen every time, but maybe 50% of the time?

When this happens, it says it's falling back to Software rendering, but a black screen appears instead. The game is still running, audio is playing but no display. You can switch internal resolutions up or down to force it to initialize the OpenGL renderer again and it usually comes back.

No idea if this is a bug in duckstation, Retroarch or a GL driver bug. I'm using glcore.

@pedrovay2003 well the keys were leaked many years ago. Possible that they are in there. Or they have some hackey way of decrypting like the programs that will extract a clean iso from a bought pbp.
You may be the one of the very few people to attempt to run a DRMed file in an emulator, because for the most part, it should not work.
Also beetle-psx is practically the same emulator as mendafins.

@dreamcastkid Thanks man

@leon21
You can find old versions of Retropie here - https://github.com/RetroPie/RetroPie-Setup/releases

To be honest, I would try a different version of the rom and see if that works rather than downgrading Retropie.

@saccublenda said in [[Solved] Pixelated and juddery background layer in > > I can use the hotkeys to browse and control the retroarch RGUI, but I cannot press the start button to start this game.

Try changing the controller type from DualShock to standard.

Thx - I managed to fix this problem with the multitap emulation option - I made an edit/update below: https://retropie.org.uk/forum/post/248454

@george-spiggott said in General Duckstation discussion:

Has anyone succeeded at running any games at 2x resolution at a reasonable speed? Even on an overclocked Pi4 doesn't seem up to this. This is certainly an emulator that will grow in usefulness as the capability of Raspberry Pis increase although I think I will probably stick with PCSX Rearmed in the short term.

I have been running a few games (spyro, ff1/2, crash bandicoot, ONE) at 4x res, with 32x msaa at over full speed (Vulkan hardware rendering). My pi4 is overclocked, but pretty much stock RetroPie.

@clyde said in Scraper fails on PS1 .chd files where it succeeded with .cue+.bin:

I'm using RetroPie's chdman and Skyscraper with my PS1 and Mega/Sega CD games, and I have only one game that can't be scraped in either cue or chd form (Kyuutenkai: Fantastic Pinball).

Thanks for this, it finally forced me to figure out SkyScraper. OMG the SkyScraper output looks so much better than the default scraper, and it handled the CHDs like a champ.

@danmac2 said in No Dialogue or Music in PSX ROMS (pcsx-rearmed):

@dankcushions I have every BIOS you can think of in the bios folder

ok, and the verbose log?

@Clyde Thank you that is good to know.

I have moved my question about the 2nd controller to a new thread so as not to contaminate and confuse there. thank you all.

My favorite for all games is crt-pi, I love the look that the scanlines give. It looks good with everything from psx, to gba, to snes, to arcade.

@Rion I would've liked video evidence, but o well. I don't see it.

I used PSX2PSP for the PBPs and CHDMAN for the CHDs, both run in Windows 10. Clyde is right above with the pro's and cons. The PBP app uses a pretty easy to follow GUI whereas CHDMAN requires you run the executable in the same location you have the BINs and CUEs. It was a batch file I'd gotten from the retropie docs pages.

@mitu That worked! Hero! Thanks for your quick replies!

I couldn’t find anything in Retropie 4.6 beta.

From the 4.6 announcement:

RetroArch updated to v1.8.5.

Support for real CD ROM, with the ability to dump the disc image.

I found a YouTube video using Retroarch but it mentions a download folder which I don’t have.

Try looking in \\retropie\configs\all\retroarch\downloads

I also have no cores in Retroarch with which to play the disc.

What disc did you rip ?

@dankcushions I provided the information of my raspberry unit to the best of my ability in the posts above.

I tried reinstalling. After reinstalling had to imput login information at the boot screen. Even after the update the ps1 emulator doss not respond to button presses.
