@hermit
try it but still no :\

I noticed that lr-reicast has a different function for savegames. maybe it can not write on your HD.
try setting everything to SD

shavecat

@hermit
No still not :
dont get why it worked on the start and now not.
that is right also :\ weird

lr-reicast = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-reicast/reicast_libretro.so --config /opt/retropie/configs/dreamcast/retroarch.cfg %ROM% </dev/null"

so at the beginning it worked and then stopped?
maybe you have a version of the bios incompatible with lr-reicast
I use :
dc_boot.bin md5=e10c53c2f8b90bab96ead2d368858623
dc_flash.bin md5=0a93f7940c455905bea6e392dfde92a4

Yes yes yes yes yes...

I'm able to play House Of The Dead 2 - Sega Naomi Arcade using Lightgun on Raspberry Pi thanks to this thread.

I've also managed to get Confidential Mission and Maze Of Kings both on Naomi Arcade working well too.

I wasn't able to the get the existing Lightgun support in lr-Reicast to work but was able to interface directly with the Sinden Lightgun. Hopefully we can get the existing support functioning across all the games in lr-Reicast, if not I'll make my hack more generic so anyone with a Lightgun device can play the Sega Naomi Lightgun games till the full support is working.

House Of The Dead 2 is quite glitchy on graphics and sound but still playable. The Dreamcast version also works and has less glitchy graphics but I couldn't get the Lightgun to work. It does work OK with a controller if you want to play without a Lightgun. Confidential Mission and Maze Of Kings both work quite well.

Atomiswave lightgun games like Ranger Mission, Sports Shooting USA and Extreme Hunting work too but I haven't yet been able to get the Lightgun controls to work.

@MrLightgun that's pretty neat! I see what you mean with the graphics being a bit glitchy. Dynamite cop has the same flickering triangles. Not sure if this is a short coming of the pi or the emulation.

BJRetro

@quicksilver yeah a good amount of Dreamcast games do that (cannon spike runs really nice except there are so many of those black triangles interfering it becomes unplayable). I think it is the emulation and that for more powerful devices they developed a rendering fix but pi is not powerful enough to handle the fix. Great to hear about your progress with the sinden lightgun @MrLightgun !

MrLightgun

If anyone is clever enough to get Virtua Cop 2 Dreamcast working on the Pi I will be forever grateful!

I've tried both the Japanese version and the USA Sega Smash Pack version and they both crash straight after the Sega splash screens. I've tried a few random graphics settings in the hope it might work but no joy yet.

Ah that's a shame, I hoped it was just an early defect with the Raspberry Pi support, not an a known issue. However the Dreamcast version doesn't have them so just need to get the Lightgun working with that at some point. Thank you, the project is getting there slowly.

here we are a little going offtopic
try to open a new topic and enter all your lr-reicast settings ;)

/config/dreamcast/emulators.cfg
/config/dreamcast/retroarch.cfg
/configs/all/retroarch.cfg
/configs/all/retroarch-core-options.cfg
-etc...

another interesting test could be to create a new system dedicated to lr-reicast
;)

shavecat

@hermit
will give it a try ,
once my new pi will arrive ;)

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.

Darksavior

@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.

Efriim

@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.

mitu

@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.
