Settings>Video>Synchronization>Sync to exact content framerate. Turn that setting on and it will fix the weird tearing/jitter.

So while the above is true, I have noticed that turning this setting on globally harms performance for some emulators. Therefore I would only recommend that you turn it on for cores that specifically need it and have a threaded rendering option.

@rejesterd quake 3 split screen works with redream. It was just added in experimental packages.

@quicksilver It's great! Performance has been fine so far.

Yep....you have got to update the retroarch settings just for the dreamcast emulator in /opt/retropie/configs/dreamcast/retroarch.cfg

well.... that's what I did :)

Hopefully this isn't too old to respond or need to start a new thread, but while on my Pi 4 using LR- Flycast, the few games I have seem to run fairly well, the controller sensitivity is too much to even navigate the menus properly.
I am using an 8bitdo SNES controller and a Pi 4 with official PS.

@KN4THX Yeah, I would start a new thread and post your exact steps and observations. "sensitivity is too much to even navigate the menus" is a bit vague. Be as specific as you can.

I am having a wierd problem.
I have Rpi3b with latest stretch retropie 4.6 version. The reincast and flycast are also latest from source.

The game "Revolt" is working perfectly. But, I am unable to see any menu in the game. I just see all the graphics and able to start the first level of the race. But even in the race I am unable to see any direction symbols or the powerups gained. I tried both reincast and flycast and also tried europe, US CDI and GDI versions. All have the same issue. The game is running at a consistent 25fps. But the menus and directions and powerups gained are bot shown. I also tried Dead or Alive 2. But inspite of running slowly it does have everything emulated perfectly.

On the Pi 4B i have manage to get working Marvel vs Capcom 2, Capcom vs SNK 2, Spawn, Techromancers, Zombie Revenge and Gauntlet Legends using Redream.

Ms pacman works flawlessly on pi3b at 50fps with both reicast and flycast. I prefered reicast because it have better latency compared to flycast on Ms pacman.
And this is better then PS1(locked at 30fps with inferior graphics)

You mean Ms. Pac-Man Maze Madness because normal Ms Pac Man you can run that using mame and would get the full speeds.

Most Dreamcast games I've tried on the Pi4 are working great using Redream and Flycast. Redream seems to have a slight edge on the performance front (but might be perception rather than reality), but Flycast has the whole libretro flexibility behind it for custom controls and whatnot, which makes it better for my setup.

Worth mentioning (for me, at least) are Dynamite Cop, Virtua Tennis 1 and 2 finally rendering properly, Dead or Alive 2, Cannon Spike, Project Justice (finally rendering well), Ikaruga and the MvC2 and Capcom vs SNK games (though if I recall correctly they already ran fairly well on standalone Reicast on the Pi3B, bar some graphical glitches).

Naomi and Atomiswave games also run fairly well on the Pi4 on Flycast. Not sure if we have a thread for those around here, but that's really where most of my fun has been coming from. Asides from Metal Slug 6 slowing down to almost single fps at the end of stage 1 and Samurai Shodown 6 also being very slow unless I do something every time on the core options menu, in a non-deterministic fashion, and regardless of saving it as a config file. Still digging into that so that I can report something more specific on the lr-flycast GitHub repository other than "it seems to happen but I don't know why or how" :)

arm_freq=1450
gpu_freq=500
core_freq=500
v3d_freq=500
sdram_freq=500
sdram_schmoo=0x02000020
over_voltage=6

This is for RPi 3B+??? is recomended for all emulators?
With this configuration, works perfect Virtua Tennis 2? (emulator? redream, flycast, reicast???)
thx

I believe for DC on the 3B+ your only option is flycast and reicast since redream is better supported for the Pi 4B.

Is there a guide anywhere for setting up NAOMI to work with Retropie?

shavecat

@Krakatoa
u just need the namoi bios in the folder dc bios
"Accepted File Extensions: .cdi .chd .gdi for Dreamcast ROMs, .zip for Naomi/Atomiswave games.

Place your ROM files in"
https://github.com/retropie/retropie-setup/wiki/Dreamcast

Krakatoa

@shavecat thanks, will that separate the games between dreamcast and NAOMI, or will they all be under the dreamcast umbrella?

shavecat

@Krakatoa
whatever u wanna or editor the es_system and add another console NAOMI or just add them to your dreamcast easy way ;)

Krakatoa

So I managed to get some Atomiswave running (what an awesome system!!). I have a question though. Some of the games don't recognize controls when running. Is there a fix for this? I recall reading somewhere about deleing the eeprom.

Also, I am still unable to launch any NAOMI games, it just boots me back to the emulation station. What version of Bios did are you all using to launch? At the moment I have all the bios' in the bios/dc called naomia.zip. I'm using he MAME rom alpiltdx.zip. NV M figured it out

You mean the games with zillions of analog controls ? Make sure the game is mapped to controls that actually exist on your controller in "quick menu > controls", if that's not the issue then yeah, try deleting the eeprom.

Krakatoa

@barbudreadmon I don't think its the analog control issue, as the coin and player select don't work either. I deleted the eeprom and a game booted, but I couldn't get past the service menu, even with a keyboard plugged.

Such a fun machine though, so I will keep persevering.
