Sega Naomi with BeetleDC

DTEAM

Hi

Has anyone tested It on a Pi4 with Retropie?

https://www.libretro.com/index.php/reicast-libretro-now-supports-naomi-other-additions/

https://www.libretro.com/index.php/category/beetledc/

It seems to be more convenient / frendly user for roms formats ( .dat/.lst or .bin/.lst pairs).

Regards

Hm, there's no BeetleDC, it was a very temporary name (which lasted for a few weeks) for lr-reicast and afterwards it was renamed to lr-flycast, which is available already in RetroPie.
And yes, Naomi ROMs are supported.

EDIT: .lst/.bin format is deprecated for lr-flycast, use the MAME roms (and .chd when needed) for Naomi games.

Naomi 1 Games work great with lr-flycast on the Pi4 :)

I'm using .zip format for roms and every single game i've tried works perfect ... can't ask for anything more friendly than that.

For games that need .chd .. just extract into a folder named the same as the .zip file and the directory location as the .zip file and it works fine :)

Thanks for the chronology.
How did you manage to no longer see directories in your Retropie list and only see the zip files.

@DTEAM

Emulationstation Setting > Other Settings > Parse Gamelists Only > On (then restart Emulationstation and the folder is gone from the gamelist)

and i think if the .chd folder did get added to the gamelist.xml which is located

/opt/retropie/configs/all/emulationstation/gamelists/naomi

note: the default folder for naomi and atmosiwave games is the dreamcast folder. I manually created the naomi and atomiswave systems as per the Retropie Wiki Instructions.

i just deleted the .chd folder from the gamelist.xml and kept the reference to the .zip .... at least i think i did that ? was a while ago, can't quite remember.

@ReadyPlayaWon
Thanks
I don't like the ParseGamelistsOnly option because It hide the "unsrcaped" games
I'll try to figure out something like I did for Daphne emulator

I already set separated systems for Atomiswave and Naomi . I did the same thing than you .

It works.

i have scraped every single game on my system (all have metadata, images and videos) ... so it's not an issue for me. Oh well, i don't know of any other way, sorry.

@ReadyPlayaWon

My problems are with Lr-Mess systems like Gamate , FM Town Marty, etc. It's not a walk in the park to scrape them . I edited my gamelist manually with pictures from the net, my own videos, emumovie packages, hyperspin datas , etc.

I fixed It! My problems was my extension list in platforms.cfg and es_systems.cfg files. I had written .chd, so that's why I saw the folders. Now I use:

Platforms.cfg

naomi_exts=".7z .zip"
naomi_fullname="Sega Naomi"

es_systems.cfg

<system>
   <name> naomi </name>
   <fullname> Sega Naomi </fullname>
   <path> / home / pi / RetroPie / roms / naomi </path>
   <extension> .7z .zip </extension>
   <command> /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ naomi% ROM% </command>
   <platform> naomi </platform>
   <theme> naomi </theme>
 </system>

and evrerythings work perfecly.....

By the way, Sega Naomi with Atomiswave are one of the coolest thing on Retropie!! It's absolutely amazing. I just can't believe I never installed It before today. Shame on me!

Good link to know:

@DTEAM

And the cool thing, there is a number of them that got a release on the Dreamcast (little brother to Naomi) as well ... a few games i had issues with, the Dreamcast version plays great with Redream .. or lr-flycast if there's any probs,

Thanks for the es_system.cfg advice .. works a treat :)

Hey out of curiosity, is there a specific mame romset that has the correct Naomi ROMs?
