@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.

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?

No.

How are the temperatures-CPU usage with Saturn and GameCube games ?

I've got RetroPie manually installed over a Rasbian Lite Image no problem, is there an easy way I can transfer my existing emulation station / retroarch configuration from my Pi3 to my Pi5 - or is this not recommended?

mitu

@StuMcBill EmulationStation configs can be copied from /opt/retropie/configs/all/emulationstation between systems. If you have scraped your systems and stored the media in the ROMs folders, copying the folders should be enough.
For RetroArch, what configs do you think you need ? Did you have overrides/shader presets, input remaps ?

In all honesty the only things I think I’ve configured in Retroarch is a crt shader and cheats. Nothing I couldn’t recreate quickly. It’s the emulation station things I’d want to copy.
Thanks.

@mitu The gamecon driver is not working. https://pastebin.com/Qj7Z95KB
If raphnet has the usb the adapter I want in stock then I'll switch to that someday.

Looks like a build error, but regardless of that I suspect all of the GPIO related drivers are not working with the Pi5. Haven't taken a look at it yet; all the I/O is handled by the on-board RP1 chip and I think the current approach used by the GPIO drivers to read/write to the kernel memory will not work.

Darksavior

@mitu No worries, I thought it might be a simple script fix.

Fixing the build, yes, but actually working - I doubt it. I'll probably fix the build, but for the actual functionality it may be a bit problematic since I don't have a GPIO based test bed.

So, to gather some information so far, if someone wants to test RetroRie (experimental) with the RPi5, they need to add :

For Bookworm Lite 64 bit

To the config.txt file

kernel=kernel8.img
overscan_scale=1

For Bookworm Lite 32 bit

arm_64bit=0
overscan_scale=1

To change the resolution (optional) :

add to the end of cmdline.txt file the following:

video=HDMI-A-1:"add_your_width"x"add_your_height"M@"add_your_refresh_rate"

Example for 1080p 60HZ resolution:

video=HDMI-A-1:1920x1080M@60

There's no need for the kernel line for 32bit, just arm_64bit=0 (as it's already done for the Bullseye weekly image). The line you added forces a 64bit kernel.

retropieuser555

Think I've found a way around the kernel problem. You can bypass the mupen64plus 4kb issue by changing the configs so it uses the pure or cached interpreter in mupen64plus.ini and retroarch_core_options.cfg.

https://github.com/mupen64plus/mupen64plus-core/issues/1047

And flycast can be built changing this memory line mentioned here, it worked for me and now have lr-flycast-dev and standalone flycast built and working in the regular kernel.

https://github.com/flyinghead/flycast/issues/1288

Those are the only two emulators/systems I found I couldn't run on the default kernel, there maybe more.

windg

@retropieuser555 Thanks to report the issues!

retropieuser555

One more thing to note, if you attempt to install ppsspp, supermodel3 emulator, fallout-ce and run it outside the desktop (these are apps that don't require a window to be opened like Dolphin)

You get audio and a scrambled image on the screen, the log doesn't have errors as such but does have this line in each case:-

WARNING: v3d support for hw version 71 is neither a complete nor a conformant OpenGL implementation. Testing use only.

So seems like a pi 5 problem. I tested these and they all ran in the desktop environment (I mean they are running here, just without the video output)

How would I go about adding this? I tried doing it via Cyberduck SSH, but when I try and copy it back, I get a permission denied error.

Edit - Managed it via terminal using sudo.

Darksavior

@StuMcBill To ssh, you need to enable root, set a password for it, and then login as that. The RetroPie docs go in detail.

You can also put the card/stick in your computer and edit it that way.

StuMcBill

Ok, so I have this up and running, however I have a couple of questions.

When I boot up, I am not getting a splash screen I get an error saying "splashscreen is not available for your system (rpi5)" - presume this would be a known issue which will get fixed in a future update.
When the system boots, it defaults to RetroPie Settings - Splash Screens - can I make it default to Arcade?
I'm getting these errors also
WARNING: v3d support for hw version 71 is neither a complete nor a conformant OpenGL implementation. Testing use only.

Nov 09 21:41:41 lvl0: VolumeControl::init() - Failed to find mixer elements!

retropieuser555

@StuMcBill splashscreens, they don't work on 64 bit as they're run on a process that doesn't exist outside 32bit.

Probably there will be a replacement like VLC, but the pi5 boot is like 5 seconds lol not sure I'd wanna elongate the bootup personally.

Don't think you can force Emulationstation to pick arcade first, it should just do it. Maybe remove splashscreens if they're not working anyway?

@windg said in Raspberry Pi 5 - official announcement:

So I left the temperature check on in terminal SSH while playing, I couldn't get it into the 60s. I have the active cooler. I didn't check if the fan kicked in, I didn't hear it if it did.

This was testing Naomi 2 games and the pi really struggling with that framerate wise

Edit: Flycast has a fix now so building it from master it should run fine without the kernel changeover
