Raspberry Pi 5 - official announcement

@skankieflank
RPi5 it's a new product and it needs time so some things to be polished. You can check RetroPie GitHub page to see the progress of the project or better install it in the Bookworm lite to test every change. For other systems, better ask in their forums, as they know better.

@skankieflank pretty much just wait for the official releases. Pi 5 support does exist in one of the testing branches in gitlab I think according to this:- https://www.phoronix.com/news/Mesa-23.3-rc1-Released

If you go the manual route there and install it expect instability and bugs though.

I meant to ask @Darksavior did you attempt an overclock? Reading the odd few managed 3GHz/900MHz but most seem to bottom out at 2.8GHz/800MHz?

Darksavior

@retropieuser555 I only managed to get a 2.8Ghz cpu overclock without overvoltage. I tried 2.9Ghz and 3Ghz/1Ghz with some over voltage settings from Jeff Geerling but it kept freezing. I didn't try 900Mhz on the gpu but I don't really know what would benefit from an extra 100Mhz.

At this time, emulators need optimizing and fixing. lr-flycast and all n64 emulators don't load and crash. Using the glcore or vulkan renderer on any emulator is actually much, much slower. Unless vulkan is only useful with dreamcast and n64 but I can't test those yet. Then there's the issue of someone possibly needing to port the standalone dolphin and aethersx2 to run without the desktop. I won't be using the desktop.

@Darksavior Try with the newer version of lr-flycast, i hope it works with Pi5, see: https://github.com/RetroPie/RetroPie-Setup/pull/3789

Darksavior

@windg I tried it a few days ago and got the same crash. I don't believe any more work was done when it got pushed to the main repo. I'll try it again when I can and post the error message.

@Darksavior Please note that the default GPU (V3D) frequency appears to be 960 MHz and not 800 MHz. This was also mentioned by one of the Pi engineers when I asked them on the forums. The documentation on their web page states 910 MHz, but that's not correct. Here's what my Pi 5 says:

vcgencmd measure_clock arm core isp v3d hevc
frequency(0)=2400007680
frequency(0)=910002304
frequency(0)=910002304
frequency(0)=960003072
frequency(0)=910002304

So beware of setting v3d_freq to 800 MHz in config.txt, as that would likely downclock it.

@mitu said in Raspberry Pi 5 - official announcement:

You can install manually if you wish, the basic things should work by now.
Note that - since Bullseye - there's no longer a default user included in the OS and upon 1st boot you'll be prompted to create one. You can skip this step if your use the RPI imager to write the image and optn the advanced options to set the name and pass of the default user. The RetroPie image pre-sets the user automatically, but if you're starting from a Lite image you'll need to either configure it in RPI Imager or set it up on 1st boot.

I didn’t realise I could manually install RetroPie before official release from you guys. I got my Pi5 delivered last week so will give it a go soon and try my Controlblock too.

Darksavior

@Brunnis Good to know, thanks. Right now, I've only set my cpu to 2.8Ghz and that's it. I'm not touching gpu speeds.

@windg I rebuilt lr-flycast-dev and it still crashes. I also got the same crash when building from the guide on the flycast dev's github. Here's the log: https://pastebin.com/Tq7dynin

retropieuser555

So I got my Pi 5 4GB with an active cooler and official power supply in the post. Having a quick go with a manual 64bit bookworm install on a regular SD card.

Same as you @Darksavior can't get N64 working, tried all the various mupen64plus versions, the lr-core, and lr-parallel. Nothing will load and I get a segment fault.

Same for flycast, I can build the lr-flycast and standalone but again segment faults.

Saturn though, I got Saturn-beetle working and oh boy, Sega Rally, Daytona USA, House of the Dead. All working perfectly :-)

Things like nes wouldn't load for me. lr-nestopia or lr-fceumm

Killer Instinct 1 and 2, I know someone mentioned above, work great on lr-mame2003 for me. When it does the character tower scroll it pauses to load in the fight but then in gameplay it's perfect. Not sure if that pause is a mame problem or part of the original game.

lr-dolphin I can get gamecube games (Wii ones seem to just crash) loading but still can't get the controller to work oddly. Fwiw wind waker the menu looks amazing and runs really smoothly. So given that's the engine of the game itself and not an fmv, hopefully it plays well.

lr-desmume works pretty well; gave Hotel Dusk a shot as I know that intro can be a bit iffy on low powered machines, it runs fine and the 3d in the lobby at the start is ok. Good news considering drastic never had a rotate option so games like hotel dusk and last window were impossible to play.

Darksavior

@retropieuser555 I'm using lr-mesen for nes and that works. I haven't tried those other nes emus.

lr-dolphin worked fine for me for wii. I'm using wbfs files if it matters. It's slow with 3d games.

I've had controller issues but it might be the pi5. Sometimes I need to re-connect my sn30 pro on startup.

Can you boot with kernel=kernel8.img added to /boot/firmware/config.txt and see if you still get the crash with the new Flycast ?

can you test them in lr-mame?

retropieuser555

@mitu That did the trick thanks! standalone flycast, lr-flycast and lr-flycastdev, lr-mupen64plus,lr-pscx-rearmed all boot now. 007 goldeneye has no slowdowns in the Dam that it usually has bumped up a few resolutions to 1440x1080 (edit:- sorry this is meaningless I forgot to change native resolution to a multiple)

Widge

@mitu This worked for me too. Thanks mitu

Darksavior

@mitu Yes, that works. It also made n64 work. Thanks. So, this kernel8 is a non-optimized kernel for the pi5?

It looks like lr-flycast-dev does take advantage of vulkan. 1440x1080 internal res with 1080p output res was getting me ~50fps with Sonic Adventure 2 with gl. Vulkan made it 60fps with minor unnoticeable dips.

lr-mupen64plus-next didn't do so well with Goldeneye. It seems to handle 2x internal res at 1080p output res until I turn on the first level and then I get major dips. No change if it's native res. I chose vulkan for it but it used glcore.

No, it's a kernel with 4KB pages, instead of 16KB that's the default for Pi5 (and the reason this doesn't happen on a PI4).

Some applications/libraries assume 4KB and they won't work with the default Pi5 kernel choice. There are a few issues reported for Bookworm on the bookwom-feedback tracker:

https://github.com/raspberrypi/bookworm-feedback/issues/107 - this lists Wine/Win64/Box86 not working
https://github.com/raspberrypi/bookworm-feedback/issues/91 - Scratch 3

For now I think it's enough as a workaround, but I'm wondering why this happens just on Linux. AFAIK, Flycast works on modern macOS when running on Apple Silicon (M1/M2 chips) and macOS works with 16KB pages only on those ARM systems.

@mitu given that bug stops things like Scratch I'm sure it'll get fixed pretty quick, can't imagine pi foundation will be happy that's not working

It doesn't seem to be an OS issue, more like an application issue. The Asahi Linux project stumbled upon this when running Linux on the Apple Silicon - see https://github.com/AsahiLinux/docs/wiki/Broken-Software.

retropieuser555

XNU (macOS) gets around this by supporting independent page sizes in userspace, however we have no such mechanism in Linux and likely never will.

Oh right. So basically software will need a fix in each case?

@Darksavior

At this time, emulators need optimizing and fixing.

100% agree, I haven't touched an overclock at all and it doesn't feel like the system is necessarily struggling with things. I doubt most users will attempt or worry about 2x 3x resolutions for games and such. Maybe have it as an option like with mupen64plus on the pi4. I'll give lr-mesen a go given that lets you do the texture packs anyway

Oh and I opened a bug report for flycast and it might be as simple as this, I'll try later on. If it works, would it work if there's a check in the lr-flycast or flycast script if it's arm-cortex a76?
