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.

@Krakatoa Searching here will help, specifically here.

Any games in particular you can mention? I tried a few and they worked well, only a few had real input challenges but they were surmountable.

I find that some games actually crash after some runs on load, and deleting the eeprom fixes it - Metal Slug 6 and Samurai Shodown 6 being the main ones that come to mind, but probably others will have the same issue.

Krakatoa

@pjft Thanks, yeah the one in particular was Faster than Speed. It booted up fine, but none of the controls worked

pjft

@Krakatoa Haven't tried it, apologies. It shows as running OK on the compatibility list.

See if this helps: https://github.com/libretro/flycast/issues/865

From the search I shared :)

@Krakatoa In my case it works on my Dualshock 3 controller. Analog sticks for steering, though, can't have them on the dpad.

Faster than Speed

That's one of the games that came to mind when talking about games needing a bit of remapping, and tbh i don't expect it to be playable on keyboard anyway (requires 3 analog axis).

Krakatoa

@barbudreadmon I'm hoping to map it my arcade sticks, with six buttons. If not I can my my USB Nintendo controller.

Well, good luck with remapping then, but as i said it's using 3 analog axis, arcade sticks have none.
