Raspberry Pi 5 - official announcement

Probably quite useful in the context of emulation. Even Dolphin's system requirements is only 2GB Ram

Can it play CARNEVIL?

Playable enough with Mame2003 Plus. Here's a video from @Widge playing it

Jiryn

@mitu Thank you!
I thougth 2010 would be better for this.

I find the following interesting and am sharing it here in case anyone wants to try it: NUMA Emulation speeds up the Pi 5.

It also looks like we'll have an official implementation soon.:https://forums.raspberrypi.com/viewtopic.php?t=376730

@sugarfree Oh, wow. That is cool!

I wonder if that'll help Saturn 3D games run at 60fps rather than the current 55fps, and (unlikely), seeing Time Crisis on MAME running full-speed as well would be fantastic.

@sugarfree I did the update late last night but I didn't necessarily see any big improvements but tbf I was only looking at GameCube stuff which seems more a raw gpu bottleneck than anything else. I imagine compiling will be faster which is nice though

mitu

I don't think the NUMA changes are integrated yet - if https://github.com/raspberrypi/linux/pull/6273 is the pending change, is not merged in the RPI kernel.

55 FPS with all 3D games? So far, I've only found two Saturn games that don't run at full speed. One is Die Hard Arcade, and the other is Virtual Fighter. I'm using a 720p 60Hz resolution.

pjft

@sugarfree Well, I haven't tried a lot of games to be honest, and when I did it was early in the Pi5 lifecycle. Die Hard Arcade was definitely one of them, but I seem to recall that Virtua Cop 2 also fell in the same bucket, at least. Other games I am likely to have tried were Sega Rally/Daytona/Radiant Silvergun, and I want to believe that if any had been able to run consistently at 60fps I'd remember. At the time we only had one Saturn emulator running on the Pi5 64-bit OS, lr-beetle-saturn I think? Do we now have yabause/yabasanshiro, libretro or standalone, or is it still just the one?

sugarfree

@pjft We have two emulators, lr-beetle-saturn and lr-yabause, that have lower accuracy but can run some games faster. For example, Die Hard Arcade runs at full speed (but without sound).
I hope it's possible to install lr-yabasasnhiro or the standalone yabashashiro to bridge the gap with lr-beetle-saturn.

Update:After applying the NUMA patch, Die Hard Arcade (USA) bin/cue runs at full speed (60 FPS) with the Beetle Saturn emulator. There were no improvements with Virtual Fighter. Maybe some games would benefit from this patch. I was wrong, sorry.

Quick comment: On Pi5 , with lr-flycast-dev, you can run Naomi2 with Vulkan and at fullspeed (or almost) with good sound quality if you set Auto Skip Frame to Maximum in

Retroarch UI --> quick menu/core options/Performance

retropieuser555

@DTEAMhave you tried Wild Riders on that? I've found with standalone flycast there's a handful of Naomi2 games it can't really run, Wild Riders being one of them. When you do jumps or there's a ton on screen it slows down a lot

pjft

@sugarfree Oh, I hadn't seen the edit and was coming here to try out the NUMA patches as well but, in that case, I'll stay put :) Still, I updated lr-yabause, lr-beetle-saturn and while we're at it lr-flycast-dev per @DTEAM 's recommendation. Thanks!

Yes, big improvement for that game too with that setup. All Naomi2 games run normally .

New edit: I also installed the NUMA patch and my Pi5 is "overclocked" , I don't know how useful this is.

#new overclock
over_voltage_delta=50000
arm_freq=3000
gpu_freq=1000

For Flycast, in emulator.cfg, create a line for the system UI

flycast-editor = "/opt/retropie/emulators/flycast/flycast --config window:fullscreen=yes"

In the UI, you can set your controller, the language and also, you can set performance in "video" ---> Performance, Automatic Frame Skipping to "Maximum"

Wild Riders and the other games will be playable for NAOMI2

I haven't tested lr-flycast vs flycast for overall performance. For Wild Riders. quickly, I don't see a big difference. Graphics are better with flycast, but less choppy with lr-flycast (almost perfect) even if it's very good with Flycast.

Maybe for other games, it's better with Flycast, I don't know.

retropieuser555

@DTEAM yeah you don't need an dedicated editor function necessarily; you can just set a hotkey for getting into the flycast GUI, like with ppsspp and make the adjustments for either global or per game settings. But I will give it a try in a few weeks, in the middle of a house move so don't have access to pi stuff

sugarfree

Hello. I would like to ask if someone has installed RetroPie on a 2GB board? Thanks.

Master Dev

@mitu not exactly playable when it crashes before the end of the game

mitu

@Master-Dev Not sure what you're referring to.

@mitu carnevil crashes before u can finish the game
