@shavecat A lot of issues here, again, if it worked previously, it's impossible it came to this without any action from you

First issue :

creating dir: /media/usb0/roms/dreamcast//dc/data
mkdir(/media/usb0/roms/dreamcast//dc/data) error: No such file or directory

The actual path it's trying to create is system_directory/dc/data, where system_directory is your RA bios folder, since it thinks your bios folder is your rom folder, it means system_directory is not defined in your retroarch.cfg, which is pretty bad because it'll also search for your bioses in /media/usb0/roms/dreamcast/dc/

Second issue :

find blahblahblah: No such file or directory
again
again

It's failing on spaces in names, so something isn't set right in your retropie setup and i've no idea what it is. Are you sure you copied the hack in /opt/retropie/configs/dreamcast/emulators.cfg properly ? A quick fix would be to remove all spaces from the name of your dreamcast isos.

@barbudreadmon
this is really wired i guess, cause the lr emulator works just fine :\

mitu

@shavecat Let me guess, you didn't modify anything and it started working ?

shavecat

@mitu
what do u mean ?
i did everything by the intersections couple of times...
the reicast just quit the games..
the lr-reicast works just fine before and still now.

hypothesis: with the latest updates the path for the bios has changed from /bios/ to /bios/dc/ ;
is not that the dc_boot.bin and dc_flash.bin files are in the bios folder?

p.s. in the wiki someone has modified the path :(

shavecat

@hermit
yes also notice it , yes its there.
if it wasnt the dreamcast (lr) also will not work ... :\

mitu

@hermit Actually the path is ok, the standalone Reicast uses that path, the Libretro core uses bios/dc. The wiki is correct, it only covers the standalone Reicast.

I have a February 8 version and it works with the bios files under the DC folder
I know little about these scripts, but in the reicast.sh file it is written:

# symlink bios
    mkUserDir "$biosdir/dc"
ln -sf "$biosdir/dc/"{dc_boot.bin,dc_flash.bin} "$md_conf_root/dreamcast/data"

https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/reicast.sh

mitu

@hermit You're right, although that only symlinks the BIOS files found under BIOS/dc. The help text for the module mentions the new location, but it's not updated in the Wiki - it was updated (at the same time as the symlink code) - when lr-reicast was added.

Does anyone know how to change the Bios language in LR-Reicast? I am soft reset to get to the Bios screen and change the language but it does not save. I assume it does this when you exit back to the game but when I do this it goes back to a blank screen.

@George-Spiggott core options

Stuart2773

ABSOLUTELY loving this core for ATOMISWAVE & NAOMI arcade games....

But....

Does anyone know how to navigate the service menu in LR-REICAST Naomi arcade games?

i can activate the menu by holding down the "start" button on my xbox360 game pad but cant select or change anything !! any help would be much appreciated

@Stuart2773 core options

Ok i'll go into details for this one : there is a core option to enable service buttons (Service and Test), one is to enter the menu, the other is to navigate, iirc i assigned those 2 buttons to L3/R3 by default (use quick menu > controls to confirm).
As to why they are disabled by default in core options : they would be always accessible otherwise, meaning if you press the service button by mistake while playing, your game is screwed.

George Spiggott

@barbudreadmon Thanks for that.

I used core options to resolve that and the analogue controls problem I had by turning off "User X Analog To Digital" in the controls menu.

I also set Frameskip to 1 which seems to speed it up a bit. I'll edit my feedback post from the other day to reflect this.

shavecat

Maybe something in the file install has change or i did wrong ?.
Can anyone look plz :)

the script is identical to mine
I would have a couple of questions:

are you trying everything on a raspberry 3B or 3B +?
Do not you work Reicast or lr-reicast?
because here it indicates that lr-reicast does not work, while reicast works well
https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/122
here the opposite
https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/140
and now ask for the lr-reicast script ..
maybe I lost some passages, but I'm confused

Thanks for that,

turned out that my 360 pad was configured to enable and navigate the menus by pressing the analog thumbsticks, had to enable the service button as well .

now everything works great.

BTW. i found this very useful site with all the Naomi Error codes and i was able to get some games previously non working games to boot up using their guide:-

@Stuart2773 are you guys running the Naomi / atomiswave games from command line? I ask because I loaded some in various formats and they aren’t appearing in the Emulation Station gamelist. If running from command line would you mind sharing exactly what the command line language is you use? I have never run an emulator / rom from command line. Would like to also join in the testing.
