@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

@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.

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.

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.

@BJRetro

this is what i did:-

created a naomi & atomiswave rom folder here :- /home/pi/RetroPie/roms

editited the es_systems.cfg in /etc/emulationstation

added the following

<system>
<name>naomi</name>
<fullname>Naomi</fullname>
<path>/home/pi/RetroPie/roms/naomi</path>
<extension>.zip .lst</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS reicast %ROM%</command>
<platform>naomi</platform>
<theme>naomi</theme>
</system>
<system>
<name>atomiswave</name>
<fullname>Atomiswave</fullname>
<path>/home/pi/RetroPie/roms/atomiswave</path>
<extension>.zip .lst</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS reicast %ROM%</command>
<platform>atomiswave</platform>
<theme>atomiswave</theme>
</system>

in /opt/retropie/configs created folders for naomi & atomiswave and copied in a retroarch.cfg in both folders (make sure you edit this line input_remapping_directory = "/opt/retropie/configs/naomi/"

i think thats everything i did, only reason i did all of the above is so i could have separate folders for each set of roms that i could load manually rather than doing the retroarch/quick menu/load content method.

hope that helps

@Stuart2773 got it thanks will try this weekend

@shavecat
looks good to me.

@Stuart2773 interesting. So, out of curiosity, what games have you tested, and how does their performance compare to their Dreamcast counterparts? Is the emulation similar, do they perform better? Worse?

I don't know the hardware in detail so I really don't know what to expect.

@Stuart2773 said in Working Dreamcast games:

<extension>.zip .lst</extension>

I don't recommend the lst format though, it is deprecated and a lot of games didn't work properly with it.

@pjft said in Working Dreamcast games:

There is no difference performance-wise between naomi and dreamcast, that's the same hardware. What's interesting in naomi/atomiswave are the exclusives, there is around 100 naomi/atomiswave games and maybe half of it got a port on dreamcast (some got ports on later generation console, some neither got ports on home console)

Heres some info on the Naomi/Atomiwave & Naomi GD hardware and games with screenshots that LR-REICAST now supports

i prefer to use the mame romset instead of using the .lst versions,
99% of the roms i have tested all boot up and work

some naomi games required you to access the test/service menu and change the config such as horziontal/vertical games, No of players. to get them to work eventually.

I posted a link to a list of naomi error codes a few posts up that was really useful.

I'll also add that some games have unfriendly default mapping, going into quick menu > controls is mandatory for those.

Hi all, is there a wiki guide to get Naomi games working?
I seem to have followed all the suggestions but my x64 system crashes at the BIOS logo screen

Thanks in advance
