@mitu for getting it working.

I actually didn't do anything besides adding that comment from the Github issue. @buzz already added the scriptmodule last year after the upstream development started.

I'm guessing my audio is working because I updated retroarch right before installing lr-recaist. However, now I have a frame counter running on multiple lr- emulators that I'm going to have to go through and manually turn off.

@pjft @BJRetro For what it's worth, i'm using alsa and sound is working.

@quicksilver I noticed that on one of my systems (where I had intentionally let retropie save a full config out). Must be a parameter change in retroarch or a default value change or something to cause it (or maybe it's a bug). To fix just restore the default retropie retroarch.cfg (It's not a good idea to save the config out anyway as you lose the function of the global config then).

quicksilver

@BuZz So just replace the retroarch.cfg in the "all" folder? Do the retroarch.config.rp-dst only come with the binary install? I updated from source and it seems that retroarch.config.rp-dst is missing from all the system config folders.

mitu

@quicksilver Only the retroarch.cfg.rp-dist exists in /opt/retropie/configs/all/, the system's config folder don't get one. However, if you enabled 'Save config on exit', your systems' retroarch.cfg files contain a full RA config, which should override your global .cfg.

BuZz

@mitu @quicksilver All retroarch configs get the rp-dist one if when updating the existing one is different from the shipped retropie version. In this case it could be the one for the system that's changed - and probably is if it's only happening for certain systems.

mitu

@BuZz Aha, thanks for clearing that up.

Does anyone know if there will be any conflicts with reicast and lr-reicast accessing the same VMU's? Will one overwrite the other?

edit:
Also is it possible to use ALSA for the standalone reicast? I think the audio works better than OMX when used on a raspberry pi.

Hey,
can someone explain me what happen here ? haha
dreamcast have some fixes ? i didnt get it from all the reading...

quicksilver

@shavecat We got a little off the original topic. We are still testing dreamcast games but we got a little sidetracked and started testing lr-reicast on the raspberry pi.

shavecat

@quicksilver .
Nice!
will be great to have more of them maybe run ... :)

BJRetro

@shavecat ok so on original topic, I have working well on standalone reicast:

power stone 2
gauntlet legends
marvel vs Capcom 2
crazy taxi 1 and 2
dead or alive 2
Virtua fighter 3tb
soul caliber
cannon spike (speed is great but there is a glitching background that renders it unplayable because the polygons keep disappearing/going black)
Sega GT
Daytona 500
Hydro Thunder (a bit slower but still fun, some might call it unplayable though)

I am not a video game purist or competition gamer so my definition of working well is “is it fun to play”? This means there may be lag a bit from time to time or the game runs a step slow, or audio cuts off or scratches for a second here or there, but ultimately I can sit down and have fun playing the game. Someone who spent years perfecting their craft in Marvel vs Capcom or Soul Calibur might see them as “unplayable” because the game doesn’t respond exactly how they are used to from the arcade/Dreamcast.

On lr-reicast I fully support putting it back as an option in the retropie setup menu for Rpi 3b+. Some of the games above run the same, some perhaps a step slower but the retroarch implementation then makes available TONs of settings to tweak that as people experiment may “fix” that or they may see it as a a fair trade off anyhow for just being able to play games without setting up the controllers and getting to access save/load states, the other options etc. the only game that on the settings above became not “working well” under my definition is Virtua Tennis. I did notice as stated by someone else that Daytona was a bit slower and perhaps gets into the verge of not “working well.”

Also, updating retroarch from binary fixed the sound issue I was having so that is also a non-issue with lr-reicast. I did get the stupid frame thing in the corner too but I am sure that will be removed again in a future retroarch binary, and I fixed the setting anyhow.

@buzz based on everyone’s testing what do you think about getting lr-reicast added back to the retropie setup menu for rpi?

BJRetro

I was also able to confirm that the setting for analog to digital controls worked in the retroarch menu for lr-reicast as expected, so it fixes the issue with games like Virtua Fighter that were originally programmmed only to work with the dpad when someone only has the choice of one joystick to control all games.

skj

@mitu

Is LR-Reicast in the experimental packages? Or can it be added there?

mitu

@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?

BJRetro

@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.

parallax

@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.
