@mitu thanks you so much for your advice!
I will try

@mitu I will try that, thank you !!!!

Thanks everyone.
It was due to bad dumps. I had bin files and a .zip romset solved the problem.
The control issue came from the 8bitdo controller. I connected it like a switch pro controller and everything is fine again.
I went further and replaced some of the original roms with dreamcast ports in order to use Redream. Really good perfs now !

@g30ff I am using LR-FLYCAST already so thank you. And deleting the vram files did the job! It's still a bit choppy, but still plays ok. Thank you both!

@unknown No, the default theme (carbon) doesn't support them.

@SireGo There are a few themes that support it - epicnoir or bluray (one of the many themes created by Dwayne Hursty - I think some of the other themes they created also support the new systems).

@greenhawk84 Sorry currently my pc has broken down so i backed up Retropie and installed Raspbean so i could continue to work from the home office, so all i got left for gaming momentarily is my RPI0 which i turned into a Sega mini :-(

@mitu said in Dreamcast/Naomi/Atomiswave no longer working.:

There are a few - glaring - errors in your configurations:

there is no /opt/openarena folder in a RetroPie installation, so your emulators.cfg files are wrong. You copied that from your previous installation, it's not compatible to the RetroPie installation, no wonder they don't work. Reicast doesn't support Naomi/Atomiswave ROMs and there is no lr-reicast in RetroPie (it's the former name for lr-flycast).

If you have created custom folder for Naomi/Atomiswave ROMs, then you should install lr-flycast and then copy the emulators.cfg, from the dreamcast system to your new system configuration. Make sure you have a corresponding retroarch.cfg in each config folder, containing

input_remapping_directory = "/opt/retropie/configs/<FOLDER>/" #include "/opt/retropie/configs/all/retroarch.cfg"

Gotcha. That's essentially what I did, since I have my ROMs on a USB drive, I just copied those cfg files. I didnt realize the dingus that had created that previous installation changed the directory structure (yet another plus to abandoning it).

Well I'm on the right path now (get it?) to fix it. Thanks for the help, yet again.

@obsolete said in Naomi Error 01:

Create a folder with the title of the game.
Put the rom inside.
Create a folder within the folder with the same name as the rom.
Put the CHD in the folder.

Working as a charm. Found out same solution after searching a few hours ^^

I've found what I was looking for. It works great ! Here is a list of atomiswave shortnames :

I made some minor adjustments to naomi bg, here is an update : naomi_background V2

Check angular theme

@shavecat said in Retropie Atomiswave Rumble Fish 1/2 no background in the game:

how do i check my romset?

https://retropie.org.uk/docs/Validating%2C-Rebuilding%2C-and-Filtering-ROM-Collections/

You could also check versus the ROmset files on adb.arcadeitalia.net, but that's just a one-time thing.

@raspnoobie said in lr-flycast does not run Atomiswave or Naomi games (log show just the launch string):

Is there a website that show the content of each ROM file? I wish I could see the log like I do with mame games, so I can see where the problem lies

https://github.com/libretro/flycast/blob/master/core/hw/naomi/naomi_roms.h

or

http://adb.arcadeitalia.net/lista_mame.php?game_sourcefile=naomi.cpp&arcade_only=0&current_version=0

@mitu I did a lot of reading around in those docs, but since I didn't require a user/pass for access I didn't know how much of that I should cut out of the line so I browsed forums until I found an example of someone doing what I was trying to.

Duly noted, though. Just another thing added to all the stuff I've learned about this stuff in the last couple months. After fixing that, Daphne works as well for me. I knew it was going to be some little minute detail. Thanks again, you're a lifesaver.

Can't open network settings, the option is grey...

@sirhenrythe5th Any progress with this (HEX editor)?
I am facing the same exact issue with these two roms and I tried with the files generated with flycast on a PC and the result is the same (i.e. still freezing at start)...

@sirhenrythe5th said in Naomi / Atomiswave problem:

Does every NAOMI-Rom need a CHD?

No, the chd are only required for games that were on optical media, in this case the zip file only contains some stuff to decrypt the chd and sometimes a default eeprom.

Updated the script. Works as you'd expect. Thanks BuZz & mitu!

@Libation

thanks you :)

That said i popped in a Nvidia GT 8800 and got the same result,
