You can play killer instinct at full speed with pi4;

You just have to do lots of workaround to get it working.

@Zuluuk I hate to be *that guy, but pi 5 is an AArch64 or Arm64 system (edit: assuming you install a 64bit OS and not a 32 bit one). X64 is computers, not single board machines.

Be that as a it may, some good videos there, hopefully people will start receiving their pi 5s and having a play around over the next month or so

In my context, it is referring to the OS being 64bit, which is a requirement for some of the emulators to run.

At the end of the day, the launcher is pretty much Emulation Station and the emulator is Retroarch, Redream, and other standalone packaged together.

I would love to stick and stay using Retropie as it has a big English user base, been using it since the pi3 and didn't convert to another distro on the pi4. The pi4 was still underpowered and barely managed to run anything past the PSX with decent speed, it was not worth the time.

The pi5 seems to have changed this. I do hope development for retropie continues as it is stable. Obviously, people would say go with a PC build instead if you want to run everything. This isn't the point though as a pi is low-powered and versatile.

@retropieuser555 was referring to the fact that x64 is not the correct terminology for an ARM 64 CPU and it's only used for Intel/AMD (64bit) processors.

Yes , i have seen this video, but i want to play it more simple as in the menu of the arcade with lr-mame.

@Darksavior sorry I'll drop the message in this thread. I pre-ordered 28th Sept as well, could be a few days yet. How you finding it? Did you install RetroPie on top of Ubuntu 20.10 or Raspberry Pi OS?

@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

retropieuser555

@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 the slang shaders from https://github.com/libretro/slang-shaders. The upstream glsl-shaders repo at https://github.com/libretro/glsl-shaders has also added a lot of 'crt' shaders that you may want to try.

windg

@Darksavior Thank you very much for the tests!

Darksavior

@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.
