Is LR-Reicast in the experimental packages? Or can it be added there?
-
@skj It is available as a scriptmodule, but it's not enabled for the RPI, only for PC installations.
-
I was able to get lr-reicast working on my pi3 and played Phantasy Star Online v2 for a little while thanks to this thread (thank you!). I toggled all the speed settings suggested by barbudreadmon. There was no audio and I had an issue with it running too fast at times and then slowdown. I understand the slowdown is inevitable but is there anything to be done about it running too fast?
-
@parallax for the audio two of us had that issue and once we updated retroarch it was fixed. I had a game briefly run fast but then it didn’t do it again so don’t know about that

Does it not run in standalone reicast? There was a recent update for the emulator if you haven't tried in a while.

@BJRetro - Thank you. Updating RA helped, I now have audio.
@quicksilver it wasn't running at all but now the standalone is running now. The speed issue also has been corrected but I can't say for sure what fixed it. As of now I prefer using lr-reicast, it's running PSO well enough for my pi3 without any overclock but I'll probably run a few tests for comparison's sake. Aside from having to quit RA anytime I change a setting (minor inconvenience) I'm quite pleased with the performance. -
Capcom Vs. SNK 2 and Street fighter 3 third strike work withouth overclocking really well
-
How does Zero Gunner 2 run on lr-reicast ? On the new standalone reicast ? Graphic glitches (polygons badly shaped) appeared for me when I updated. One of the very few games that ran worse on the last standalone build.

could we get a scriptmodule added for pi3 to the experimental section ? if certain games are running on the pi3 using LR-Reicast at least its better than nothing at all? i guess more users could test and report the compatibility of the games.

@Stuart2773
yeha , i agree if its fixing issue's we can all try different games.. -
Just tested fur fighters, runs pretty good in standalone reicast though there are some menus that flicker (perhaps due to the auto frameskip?). Lr-reicast actually runs the game more accurately without the flicker and the menus are more accurately rendered but it does run slower.

@quicksilver
Lr-reicast how can i install it too ? -
@Stuart2773 I posted how to modify the existing scriptmodule to be installable on a PI3 - https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/43. Look below (https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/48) for the BIOS files needed and where to place them and also for the modifications needed for making it run (https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/57).

I updated reicast yesterday, I noticed Jet Grind Radio renders shadows now, unfortunately they render and flash sometimes and Jet Grind Radio needs all the performance it can get. Is there a way to disable them again, or do I need the old binary? Do I have to edit the build source? Is there any rundown for reicast emu.cfg file? I've searched and couldn't find anything until I just now installed lr-reicast, which has the core options listed I could try to cross reference.
-
This is the best I can do:
-
update the retropie setup script
-
update Retroarch from the the retropie setup menu choosing the “from binary” option
-
once you reboot and are back in emulation station press F4
-
type sudo nano /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-reicast.sh
This lets you edit the lr-reicast setup script to allow it to appear on the raspberry pi retropie setup menu under experimental packages. Edit the lines motion pointed you to:
replace the rp_module_flags with
rp_module_flags=""in the build_lr-reicast function, replace the single make line with
make platform=rpi3
Press Ctrl and X on your keyboard then y to save changes.5)type sudo reboot to reboot then in EmulationStation go to the retropie setup menu, manage experimental packages, and lr-reicast should now be there. Install from source.
- type sudo nano /opt/retropie/configs/dreamcast/emulators.cfg
You will see a line that says lr-reicast= and at the very end of the line inside the last quotation mark put < /dev/null
-
put the bios files you need in the Dreamcast bios folder
-
Dreamcast should now work when you start a game.
If the paths are wrong in steps 4 or 6 let me know as I am not in front of my pi so doing it from memory.

@BJRetro
Thanks , now i can also try it too later ;) -
-
Worked for me very slow and leggy , then for some reason stop to work....
not worth it from my side.
Why is it jumping back to the emulator ? -
@shavecat I am not sure what you mean or what game you tried. But I was playing around with the settings on Virtua Fighter (yay I was right; by enabling analog to digital controls for left analog in the retro arch settings I can finally use this game on my bar top! That alone makes it worth it for me to have lr-reicast). What I found was that at least for that particular game, using the runcommand menu to select CEA-3 as the video mode (so a lower resolution)and then using the retro arch menu and turning on bilinear filtering on video settings in-game, made it run very well and also look good rather than fuzzy or jagged edges. I can tell it is still running slightly slower than the game was supposed to run originally but I can have a lot of fun this way. So the big benefit of using lr-Reicast is you can mess with the settings a lot easier and see what works best for you.
