N64DD games end Naomi 2 games works on Retropie?

saku00

The questions will be discounted but I have not found clear answers on the web

First question: Do N64DD games work on Retropie? We talk about mupen64plus but trying the .NDD files are not seen at all.

Second question: do Naomi 2 games work on Retropie? if I understand correctly the Naomi 2 core was included in Retroarch last February, any news for Retropie?

Thanks everyone in advance for the answers

First question: Do N64DD games work on Retropie? We talk about mupen64plus but trying the .NDD files are not seen at all.

Which 'mupen64plus' ? Standalone or the libretro core ?
The libretro core can load the.ndd automatically when loading a .z64 game cartridge, you just need to have a "game.z64" file and the NDD named "game.z64.ndd" in the same folder. If the 64DD game does not require a rom to load, then you can copy any rom and rename it as "game.z64". You also need the IPL.n64 firmware file places in the BIOS/Mupen64plus folder.

No news, it's not supported yet.

You need to migrate to https://github.com/flyinghead/flycast for lr-flycast, and i highly recommend adding a standalone build. It seems to be by far the best dreamcast emulator for pi4, since it doesn't suffer from the performance bottleneck of the libretro port.

@barbudreadmon is there any instructions for building the flycast standalone manually? I'd be curious to test it against redream

barbudreadmon

@retropieuser555 earlier this year, @mitu wrote an experimental install script for standalone flycast at https://github.com/cmitu/RetroPie-Setup/commit/d2e3fde006a9e81e5b8b21c424e72f04436ddba5

However i have no idea why it wasn't added to official retropie yet.

@barbudreadmon ah thanks! I didn't know that. Everything I searched only came up with the libretto version. I'll give that a read and have a try with it

I know that you are right as you are an absolute pro!!!

Because of the Achievement-Support i am forced to use lr-flycast, but, as someone who just wants to play games, i am pretty ok with this port.
Everything runs fine, but the CE-Games (tried when the CE-supporting version was online for some hours).
lr-flycast is not that bad IMO.

@sirhenrythe5th it's nice to have the option for the standalones anyway (definitely agree it's fun playing for achievements on Retroarch), I'm the same I tend to find Dreamcast support is pretty much ok. I imagine something like Shenmau probably chugs along slower than original hardware though.

Also I'm curious if the pi zero 2 w will play some Dreamcast games on a standalone flycast than the Retroarch core

Indeed, i think many games run fine with lr-flycast on pi4, yet i keep seeing people saying redream is faster than flycast, while that's only a legend born from the overhead of using opengl(es) through libretro. Afaik, it wouldn't even be a problem if vulkan was used, because vulkan doesn't have that overhead problem.

@barbudreadmon so I tried that script on a retroflag gpi with a pi zero w 2 and got this error

Any ideas? I'll test the script on my pi4 later

Edit : apologies if this is taking over the original topic abit. I can start a new thread if needed?

barbudreadmon

@retropieuser555 i'm not the author of that script

retropieuser555

@barbudreadmon no worries, I managed to build it on my pi4. Having a test of Shenmau and Code Veronica. Happily running at 30FPS and 25FPS respectively which I believe is their native speeds? I never owned a Dreamcast but it looks correct to me, no obvious audio clipping or anything. I managed to play Code Veronica at a high resolution on standalone flycast than lr-flycast. So there's definitely an improvement there

Edit: btw the above script is missing %ROM% at the addEmulator function. So it'll jump to the emulator rather than boot the rom up on startup currently. Just go into opt/Retropie/configs/Dreamcast and edit the "emulators.cfg" file and add %ROM% to the end of the flycast line.

barbudreadmon

@retropieuser555 Lots of dreamcast games were running at 30fps but i don't have the exact list (i think those 2 are 30fps but not 100% sure).
Maybe PAL was 25fps ?

retropieuser555

@saku00 so I tried some Naomi 2 games on the standalone flycast on a pi4 2gb. Good news and bad.

They boot. But they're absolute slide shows. 4-7 FPS at best.

https://ibb.co/fvXsjwn - you can see the FPS counter in the corner. So I would say Naomi2 is a no for a pi4. Not surprising given they're basically PS2/GameCube/Xbox graphic games. Maybe a pi5 or 6 in a few years will be able to handle that.
