@chaoseffect I'm on the pi4. Tekken 3 on rearmed with increased cpu clock is mostly fine overall but depending on the game's stage I still do experienced random fps drops and also the game slightly speeding up. It's pretty noticeable at default cpu clock.
Tekken 3 is running fullspeed here on (a stock) Pi4 either with ir-PCSX-ReARMed or lr-duckstation. Both with default emu settings. If you're relying on
.chdit might be interesting to recompress it using the latest chdman available as described in my 1st post above. -
@nemo93 Yeah I've been redoing my games with the latest chdman which I got from the mame package. But so far so good other than some graphical glitches most of my experience with duckstation have been really positive. My issues with tekken 3 is pretty negligible at best since the game works fine most of the time, and I'm actually happier that finally I could enjoy games that had been a crashfest in pcsx rearmed like Star ocean 2nd story.

Feature(s) request
- to support different extensions for
.chd(eg..cd[1-4]) so that games won't be listed twice in frontends (note: Pegasus does support regex / I don't know about ES).
You might be able to put images (.chd or whatever) in a hidden subdir and have an .m3u file pointing to them for multidisc games so they only show up once in the gamelist. Depends on how duckstation handles disc switching. I haven't tested with duckstation yet.
See my post here about this. Post is about SegaCD but same principle applies.
Edit: Tested briefly. Seems to work fine but I don't have any saves at a disc-swap point to test.
Edit2: Seems the memory card manager feature from duckstation didn't make it to the lr- port. Have to convert .gme saves to .mcr on the PC and move them across. Not a big deal, and better with a more complex UI anyway.

@dankcushions so far I've tested ~550 games and it went very well as stated earlier. I've updated my first post with some findings but the emulator perfectly works (at least on pi4 - stock). I've deleted lr-PCSX-ReARMed from the system given all games play fullspeed and without glitches (except for the 1 or 2 games reported).
I'm taking a 2-week break now. If you're interested I leave to your hands what I reported in my 1st post, if you want to report the "issues without fix" to the author please feel free to do so. I'd prefer somebody else to confirm these issues first to be 100% sure it's not my setup.
Settings-wise I've used pretty much default values. As discussed the most important for now on pi4 is to be sure Renderer is "Software", "alsathread" has to be enabled (sorted as per your PR) and Apply Compatibility settings must be switched "ON". I've used mostly the Crop "All borders" which works 95% of the time. The remaining 5% are usually 2D games, FMVs or still images (loading screens) that will flicker. For these the Crop "only overscan" will do just fine. For max compatibility the Crop setting should be set on "none" so up to the users to decide what's best for their setup. I just set Log level to "none" instead of the default. Bios I've been using for the whole test session is "scph101.bin".
To be fair lr-PCSX-ReARMed did also a pretty good job for many years (thanks to authors/maintainers) and still does but in term of stability, compatibility, sound and image quality lr-duckstation is superior on pi4.
This emulator is really an amazing piece of software and I'm so glad to have a fully working PSX emu now. What's nice is there will be improvements hopefully soon when it'll be possible to fully rely on Vulkan/OpenGL backends. But even without it's so great to be able to play some old goodies exactly the way they were back in the days :-)

The only thing I'm really missing from lr-PCSX-ReARMed is the internal FPS counter that shows the actual FPS rate from the emulated GTE. It's good for seeing whether a CPU overclock helps stabilise the framerate in certain games. Apart from that, lr-duckstation is a clear winner. I look forward to the day the accelerated graphics options are really usable on the Pi4.

@dankcushions Thank you and the RetroPie team for finally providing this build after so much waiting...
I'm having a great time seeing games like "Jumping Flash 2", "Tobal 2", "Airgrave" and "Tomba 2" work perfectly for the first time since I started using RetroPie back on the Pi2 in 2015.
Keep up the great work. š

Hi all.
I followed all the steps but it doesn't work for me. I am just thrown back to ES. No matter what I do.
I run Retropie 4.7.1 on a HP laptop running Xubuntu. See pastebin for the verbose log of Run Command: https://pastebin.com/vQ5pLxqm
My guess is that hardware rendering is tried which doesn't work. But since no ROM is started I can't get in to the RGUI of lr-duckstation and change it. I already tried to manually edit the config file but I don't know the proper syntax nor what file to edit manually.
Any advice is welcome, many thanks in advance.

@mrpacman17 try forcing software mode by editing file
/opt/retropie/configs/all/retroarch-core-options.cfgreplace line
duckstation_GPU.Renderer = "OpenGL"with
duckstation_GPU.Renderer = "Software" -
do you have any particular examples which slowdown with the default hardware (OpenGL) renderer on pi4? ideally with a way i can quickly verify them.
in lieu of vulkan i can be tempted to make software the default renderer for pi4 (and pi2 and 3?), but i haven't seen any performance issues in my (limited) testing of the default hardware renderer - open to ideas!
i note that a few of the PGXP enhancements are on by default - i'm not sure if they are applicable to software mode, but if they're not i would be tempted to turn those off by default if i can provide full performance.

@dankcushions Hi there.
Thanks for the advice but it doesn't work :(. What is strange that the file you mentioned contains NO other entries for Duckstation what so ever.
See pastebin for the verbose log of Runcommand: https://pastebin.com/LXzAgGwS
And pastebin for the retroarch-core-options.cfg: https://pastebin.com/e8p3jr7E
Guess something is not okay here. And thanks a lot for your help here, much appreciated.

@dankcushions I've tested a handful of games on the Pi4 (arm 2000/v3d 700) and found:
OpenGL
All tested games seem to run full speed at 1x nativewith or without PGXP enhancementstested more and it seems PGXP can cause slowdown in certain scenes. It's not terrible, but it's definitely there.
1x native with any form of antialiasing introduces slowdown in certain scenes, with or without PGXP.
2x native and higher introduces slowdown
Some of the time the emulator fails to initialise the OpenGL renderer, simply trying a second time with identical settings seems to fix it.Vulkan
AFAIK, Vulkan is not officially available in RetroPie yet, at least on RPi platforms.
[ERROR] Requesting Vulkan context, but RetroArch is not compiled against Vulkan. Cannot use HW context.Software
Everything seems to run full speed.
Scaling, antialiasing and PGXP are not available in software. -
@mrpacman17 Turn on logging in retroarch and post that log. Settings - Logging - Log to file.
Logs should appear here:
/opt/retropie/configs/all/retroarch/logs

@mrpacman17 can you please show your config files:
/opt/retropie/configs/all/retroarch.cfg
/opt/retropie/configs/psx/retroarch.cfg -

@dankcushions Hi there.

this is a non-default config, unfortunately. i would reset it by updating retroarch, which will generate a
retroarch.cfg.rp-distdefault file in th same folder. delete/rename your old retroarch.cfg and then renameretroarch.cfg.rp-disttoretroarch.cfgthat said, the line i was curious about is
video_driver = "gl"try instead with
video_driver = "glcore"From PSX folder: https://pastebin.com/yJqykEM0
looks fine
-
@dankcushions Thank you, will do as advised. Many thanks again for your hard work and time.

@dankcushions I did as requested. The file is default now and I changed the videodriver to glcore as requested. But the issue persists, see Runcommand log: https://pastebin.com/YcmcpvLM
