Pi3B+,Retroarch 1.7.6. Bios in /home/pi/RetroPie/BIOS/dc . Tried both a dc gdi game and naomi .zip game. Here's my error. Boots me back:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-reicast/reicast_libretro.so --config /opt/retropie/configs/dreamcast/retroarch.cfg

@Darksavior check if these files looks okay_
/opt/retropie/configs/dreamcast/emulators.cfg
/opt/retropie/libretrocores/lr-reicast/reicast_libretro.so
/opt/retropie/configs/dreamcast/retroarch.cfg
ls -l will list directory owns/perms
I can turn my pie on and get a better reference going, i just turned it off. I have lr-reicast installed but I haven't tried naomi so I'm kind of interested. Im really sleepyy though.

@Efriim Oh crap. It was a failed update I stopped. Ok, reinstalled retroarch. My other games work. Still no dice on dreamcast. Creating dir: /home/pi/RetroPie/roms/dreamcast/Ikaruga//dc/data mkdir(/home/pi/RetroPie/roms/dreamcast/Ikaruga//dc/data) error: No such file or directory.

@Darksavior
reicast and lr-reicast are working for me, I don't know anything about NAOMI but I added .zip extensions to es_systems<dreamcast>. I know that MAME arcade rom sets are name specific and remain zipped, They are also MAME*machine specific, so one package may not work for a different emulator. Maybe once I figure out how to run them myself first...

Darksavior

@Efriim It's a bios location issue. I've read up and there's a few posts about it but no real fix. No dreamcast or naomi games work.

Efriim

Sorry I wasnt at all more help, I built lr-reicast less than a week ago from this thread, I didn't have any problems but regular reicast outperforms it in everyway other than hwc reset and controller niceness. Again sorry, I got to go to bed, before I understand naomi.

@Darksavior You seem to have reset your system RetroArch folder, so if your BIOS files are in bios/dc, they're not picked up and RA tries to uses the ROM folder path as system. Backup your retroarch.cfg file frm /opt/retropie/configs/all and then move the .dist file over.

Darksavior

@mitu Great, that worked. Thanks.

Efriim

Oh I see it now, I guess I skipped that one for being interested in just getting naomi files to work.

Hokuto No Ken Atomiswave running at an asstastic 24fps. Held my hopes high for this one. Also tried Capcom vs snk 1 Naomi at the same fps. Yea, I won't be running this emulator on my pi.

the following Atomiswave/Naomi games run pretty well in lr-reicast :-

Animal Basket
Knights of Valour : The Seven Spirits
Jambo Safari
Monkey Ball
Powerstone 2
Puyo Puyo DA
Radigy NOA
Samba De Amigo
Shakatto Tamborine
Slash Out
Spikers Battle
The Maze of Kings

@Stuart2773 I also found guilty gear x 1.5 very good.

@Stuart2773 can you define pretty good? At/near full speed? No/minimal visual issues?

@MrLightgun

great work with the Sinden Lightgun, have you tried:-

Lupin The Third - The Shooting (naomi)

(i could not get the mame .zip version to work in lr-reicast but the .lst version does work.

I only tried the Zip version but I didn't realise that some might work with the LST file instead so I'll see if I can source them and try, thanks for the suggestion.

barbudreadmon

@Stuart2773 because you aren't using the latest version of the romset

@MrLightgun except if you like unexpected issues, there is no reason for using the deprecated lst format

Hello, someone managed to start the lr-reicast core on RetroPie installed on an Ubuntu Server 18.10 64bit machine?

This core after some seconds hangs completely the retroarch (show some graphics then freeze)...

I tried several combination but i have the same issue on Ubuntu (not server), Lubuntu and i tried an Ubuntu 17.10 32bit version too with no luck.

The Reicast core instead works but doesn't have Naomi/Atomiswave support.

The only thing that seems to work for the lr-reicast core is to create the "10-intel.conf" file and set the AccelMethod option to "uxa" but the graphics become inaccurate and everything runs slower and stuttering.

Someone using Ubuntu could help?

@fastpop72 Please open a new topic, add more details about your system - https://retropie.org.uk/forum/topic/3/read-this-first - and post your RetroArch log file (/dev/shm/runcommand.log).

try setting "DRI" to "2" instead
