Working Dreamcast games

@Efriim I couldn't honestly say, but you should get better performance than the Pi for sure.
I'm running this on a LattePanda Alpha, so more modern chipsets.
My suggestion since Batocera runs Dreamcast/Naomi etc now is to boot off that via USB as a quick test.
If Batocera works, then your custom Retropie should be better :-)

I use Retrpopie to have more control & it allows me to easily add emulators like the Sega Model 3.

Note: I'm running Ubuntu 18.10 with latest stable Mesa drivers.

Btw does anyone get a bunch of all black segments while running metal slug 6? The game was running pretty good but then I was getting portions of the stage going black.

Already mentioned above, this one needs "div matching" set to auto.

crap
yes :\

have you tried to reset the retroarch-core-options.cfg settings?
with some settings of the bios it is also reset to me

Efriim

@dmanlfc Retropie is a lot more versatile having raspbian underneath it all, I learned quite a bit from all the script modules and I'm kind of getting used to them, plus the support and active community. I liked batocera but I'd probably run into a dead-end when I want to customize anything, a USB boot is a good idea I think I can figure that out, I should unplug my harddrive just in case it wants to install though.

I haven't used ubuntu in ages (I still have Ubuntu 8.04 LTR on dvd and 7.10 on CD from when they would send you them for free) I think I may end up going with that. Except the newer version.

by uninstalling lr-reicast, these settings are not reset
the file in question is in the path /opt/retropie/config/all/
make a backup first

@barbudreadmon ah thank you very much for replying again- it seemed vaguely familiar but when I had tried to scroll through I didn’t see the post sorry.

@hermit
try it but still no :\

Just tested Pro Pinball - Trilogy ~~but it crashes with lr-recaist~~ and standalone the ball is invisible.

Edit:
I messed with some settings and it looks like I have it working with lr-recaist. I'll have to turn them on one by one to see which one fixed it.

So it looks like DIV matching has to be disabled otherwise the game will freeze with lr-recaist. Another weird thing I noticed is when you see the production studio logos at the start of the game, You have to press start right away, if you press "a" or press nothing the game loads to a black screen and nothing happens and the game has to be reset.

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 ;)
