Raspberry Pi 5 - official announcement

@retropieuser555 I accidentally almost completely removed the fan header when trying to insert a usb stick so be careful. Luckily, I managed to fix it.
I'm using Pi OS lite with RetroPie. Are there any benefits of using Ubuntu? I only game with a controller so the desktop environment is of no use to me. This will probably make me miss out on ps2 emulation unless someone figures out how to run AetherSX2 on RetroPie.
I am surprised that it can handle the crt-pi shader at 4k for most older systems so I no longer have to see uneven scanlines. I am a little disappointed that it can't handle the crt-royale shader at any resolution.
lr-mame won't build so I can't try it. I do intend to still use lr-fbneo as my primary arcade emulator but I do want to get lr-mame built for the games fbneo does not support.
I hope lr-dolphin gets optimized. Muramasa (a 2d game) runs full speed, but a 3d game like Sin and Punishment 2 does not. ~30fps. The standalone dolphin builds but crashes when loading a game. Maybe it requires the desktop environment?
-
@Darksavior if you can, try please the lr-beetle-psx with some 60 fps games like Tekken3. I hope to be possible to build it . Thanks

@Darksavior thanks for the heads up on the fan usb issue and testing out shaders and lr-mame.
Ubuntu build, I'm not sure yet I'm curious installing RetroPie on top of 20.10 rather than on top of raspberry pi OS, given a few of the YouTubers who got the pi 5 early have found standalone Dolphin and AetherSX2 won't work on raspberry pi OS but will on Ubuntu. So in theory should be able to run those from a RetroPie build on Ubuntu rather than raspberry pi OS. But of course perhaps it simply won't install RetroPie to an arm64 Ubuntu 20.10 machine as of yet.
Oh also, I'm fairly sure lr-dolphin is a lot of versions behind standalone dolphin. It's why people seem to massively prefer the standalone. And I remember Muramasa I had that on my Wii back in the day. Great little game.
Good job though anyways so far, have fun!

Does anyone here know if it will make any difference for emulation if I purchase a Pi5 4gb or 8gb?

It's unlikely to make a difference. RAM is generally useful if you run lots of applications at once. The nature of RetroPie is you're only running a small number of applications and processes at a time. 8GB Pi4 for example was huge overkill.
Except for that later revisions of the pi4 4GB & 8GB could be overclocked higher; that wasn't due to the RAM though. It's because they were board revisions

That makes sense but might the newer version of RetroPie require more memory or use memory in a different way?

Guess more a question for @mitu but I don't see why. Unless the standard became 4k display mode, higher resolution images or videos. Even then you wouldn't see that much of a strain I don't think, as even at the moment video snaps aren't particularly draining on the system. And the drain is more likely to be GPU than RAM.
Ultimately I can't see a situation where RetroPie would attempt to load lots of programs at once like a desktop computer would.
Background tasks > Emulationstation > Retroarch (or standalone Emulator) + few more background tasks
From a RAM standpoint unless Emulationstation or Retroarch suddenly become a lot less lightweight. Or maybe if a different frontend that's more intensive is used. Even then it's more likely to drain GPU than RAM

We don't create the programs that are installated - if future OS/emulators will require more memory, then you'll need more memory. Not something that is controlled by RetroPie, but also not something that's I see changing drastically (i.e. more memory required) in the near future.
If you intend to get a Pi5, then the base model with 4Gb should be enough, even on a 64bit OS.
Same advice was given for a Pi4 - if you want to use your Raspberry Pi for more than emulation and as a desktop /server system, then check the requirements for the applications you want to run and perhaps more memory would be needed (i.e. running Chrome, an IDE, file server/NAS, etc.) -
@mitu thanks for your insight. Its very helpful when trying to work out a budget. My hope for the next RetroPie version for the pi5 is to emulate all the current supported emulators but with more power for some systems like mame and possibly an addition of GameCube.

@windg I re-tested lr-beetle-psx. It looks like I set some setting wrong so I started over. New tests with Ghost in the Shell (that one got slowdowns unlike Tekken 3) 4k crt-pi shader and everything else at defaults: gl 60fps, glcore 48fps, and 40fps vulkan. Gl and glcore would default to software mode. 2x res worked only in vulkan.
Retroarch won't show you the real fps unless you goto the retroarch menu while the game is running so I used that measurement. You can have a game telling you it's 60fps but the video is jerky. I've noticed vulkan makes things much slower so all my emulators are using gl.
lr-swanstation runs fullspeed at 4k with the crt-pi shader. 2x internal res is only fullspeed at 1080p.

You can try switching to the
glcore
driver, but you'll have to manually download theslang
shaders from https://github.com/libretro/slang-shaders. The upstreamglsl-shaders
repo at https://github.com/libretro/glsl-shaders has also added a lot of 'crt' shaders that you may want to try. -
@Darksavior Thank you very much for the tests!
-
@mitu I've been enabling retroarch's online updater and installing the shaders that way. I really wanted the crt-royale shader to work but the pi5 is just too weak for it. I tried glcore but I also got a low fps. While lr-beetle-psx did use software mode for it, I noticed a lower fps with glcore and vulkan on all the emulators I tried. Maybe the mesa drivers need to be updated for it. I will try pikiss's vulkan/mesa updater whenever it works with bookworm/pi5.

I doubt that will yield better results. The version of Mesa included in RaspiOS is a modified/patched one to include the Pi5 driver. The driver is not - yet - part of any official MESA release, so updating Mesa may actually break your setup.

Is that why the couple of YouTubers couldn't get Dolphin and AetherSX2 working on Raspberry Pi OS but could on the Ubuntu 20.10 build do you think?

I haven't paying attention to this and haven't watched all the videos published, maybe the reason they were using Ubuntu is because installing the emulators was easier (using
flatpak
?) than on RaspiOS. -
I just got my pi5 and wondering if its possible to get retropie installed manually or are we supposed to wait for an official release on the retropie.org.uk website?
thanks

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. -
@mitu
Thanks for replying.I setup Raspi OS 64-Bit Lite using Pi Imager.
Is the recommended way to install retropie from terminal by following the guide at https://retropie.org.uk/docs/Manual-Installation/EDIT: I found a guide on youtube and now have RetroPie installed.
Thanks

Yes.
