presume your rom is incorrect. i believe flycast uses latest MAME romsets.

Having the exact same problem. Any Naomi based game that requires a CHD file gives a "Error 01" message on the Naomi splash screen. Melty Blood, which doesn't use a CHD file, works perfectly fine so I assume this isn't a BIOS issue (I even downloaded Melty Blood from the same source as other games). I've tried Guilty Gear XX Accent Core, Chaos Field, Border Down and Kuru Kuru Chamleon and all have the same result.

I read somewhere else that it could be a VMU issue and enabling "Per-Game VMUs" and deleting "dc_nvmem.bin" could possibly work, but I can't for the life of me find this per-game VMU setting in RetroArch...

Running a Raspberry Pi 4 with Retropie through EmulationStation. Using latest version of lr-flycast. Have dc_boot.bin, dc_flash.bin, and naomi.zip in folder retropie/BIOS/dc .

I have all of those games working with no issues. I dont use the mame romsets as they require the .chd format, but if you can find the .lst versions they work perfectly

Heres what i have for borderdown to give you and idea what to search for.

borderdown.dat (212mb)
borderdown.lst (63k)
borderdown.lst.eeprom (128k)
borderdown.lst.nvmem (32k)

I’ve been messing around and have gotten them to work.

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.

Turns out that’s just the way that it’s searching the directory for the CHD.

@swagford This is an example of how it should look

/home/pi/RetroPie/roms/dreamcast/ggxxac//ggxxac/gdl-0041

@obsolete This was the problem apparently. Putting the CHD file in its own appropriately named sub-folder worked. Thanks so much!

@swagford No problem!

Your ROM is incomplete, you're missing the chd file for the ROM or the .zip file location is incorrect (shouldn't be in the ggxxac folder).

In the future, for large log files please use pastebin.com (or a similar site) to post it.

Thank you, this worked for me.

It makes no sense, and it doesn't require this folder structure for retroarch on your windows PC, but in retropie this is required for the games to run.

You need to have (for example for Guilty Gear XX):

/home/pi/Retropie/roms/dreamcast/Naomi/ggxx/ggxx.zip
/home/pi/Retropie/roms/dreamcast/Naomi/ggxx/ggxx/gdl-0011.chd

In my case I have an extra 'Naomi' subfolder for organisation, you can leave that off if you don't want it.

Other games like Akatsuki Blitz that don't require CHD files can be setup normally in the following folder structure:

/home/pi/Retropie/roms/dreamcast/Naomi/ausfache.zip

again I have an extra 'Naomi' subfolder for organisation, you can leave that off if you don't want it.

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