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?

@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"

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 ;)

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.

Krakatoa

@barbudreadmon Good point, I will probably have better luck with my nintendo64 controller.

Krakatoa

Anyone know how to get into the service mode for Naomi and Atomiswave roms using a keyboard?

barbudreadmon

@Krakatoa did you enable the service mode buttons in core options ? they are disabled by default to avoid misspress while playing

Krakatoa

@barbudreadmon yes I enabled them thanks, but it wants me to use l3 and r3 which I don't have on my system. That's why I was wondering if you could access it ca the keyboard.

pjft

@Krakatoa You can change them in the RetroArch menu, even if temporarily.
