@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.

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.

<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.

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

SEGA NAOMI GD-ROM HARDWARE

SAMMY ATOMISWAVE HARDWARE

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

@Stuart277 hi sorry how did you set up the bios - I am seeing conflicting info. Is it dropping the zipped Naomi.zip into bios/dc/ or creating a Naomi boot.bin from one of the unzipped files in Naomi.zip or something else? And do we need to worry about romset versions like we do with Mame, I.e. need to have .xxx romset and .xxx bios? I would assume so but figured I would ask rather than spinning my wheels.

Edit: answered my own question I think. Putting Naomi.zip, naomi2.zip and Naomigd.zip bios files from Mame .185 romset in this bios/dc folder and the corresponding 18wheelr.zip from the same romset into the Dreamcast ROMs folder got 18 wheeler running (not well but running). This with editing the es system cfg to allow .zip files to appear on the EmulationStation game list for Dreamcast. Now just further tweaking and testing!

Not yet.

Please open a new topic and provide the info asked in https://retropie.org.uk/forum/topic/3/read-this-first, along with the RetroArch log file (/dev/shm/runcommand.log) taken after you start a failing game.

yeha i got confused there maybe ,
reicast works fine.
the lr-reicast just quit the games (the new install) .

Stuart2773

@BJRetro

heres my folder :-

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

the airlbios.zip f355bios.zip f355dlx.zip hod2bios.zip are game related to

Airline Pilots, F355 Challenge & House of the Dead 2

awbios.zip is needed for atomiswave

naomi2.zip is not needed as its not supported yet but i added it there anyway

hope that helps

Stuart.

@Stuart2773 ah thank you for the atomiswave file names forgot about that!

your welcome :)

just remember that some naomi games require an additional .chd file as well as zipped roms

example Virtua Athletics / Virtua Athlete (GDS-0019)

vathlete.zip
gds-0019.chd

@mitu fixed it :-)

I had to create a /usr/share/X11/xorg.conf.d/20-intel.conf file to hack the integrated intel card with the details below.

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "DRI" "2"
Option "TearFree" "true"
Option "AccelMethod" "uxa"
EndSection

Now both Dreamcast & Naomi run vi lr-reicast

BOOM!

Hopefully this helps others.

@Stuart2773 Remove naomi_boot.bin, it is deprecated and i'm not 100% sure it won't cause conflicts

@shavecat
I do not know at this point, from what I can depend
maybe it's a hash not recognized by lr-reicast.
have you tried lr-reicast with a rom that is not gdi?

shavecat

@hermit
crap
yes :\
