great build! everything is really starting to look solid.
excited about all the progress.

anyone know if it's possible to turn off the odroid "heartbeat" LED?

thanks for all the work Slaminger!!

thanks! you can use ssh to get to the console/terminal

A little "bugs":

Nintendo DS: When I press R2 the screen goes white and can't play (it freezes).
Saturn: Doesn't appears on emulator list menu, I checked and the games are in correct format and in correct folder.
PSX strange problems: If I open a psx game and close it (by button upper ABXY or retroarch menu)and open it again (or another psx game), system freezes. If I shut down by button then and start handheld again it works again. I tried puting bios just in case but same result.
Restart EmulationStation: If I close the system shutting down OK, but if I restart it by menu QUIT - RESTART SYSTEM. It takes a lot of time on restart and open Emulationstation again, and a lot of time to exit the system before restarting.

Thanks for your hard work !

you are very welcome

is that in 2.3.5 as well or only 2.3.6? I am m looking at saturn right now, it's for sure here, what format are your games? When i press R2 in Drastic, nothing happens at all. I cannot make the screen turn white. Also, i can exit PSX fine. I can't replicate these issues, besides restart taking longer than shut down does. What version are you on? what format is sd2?

saturn solved ( I had only the bin, I inclued the cue and works ok, i had to include bios with recovery metod, in SD is it possible to include in bios folder the saturn bios? I tried without success.)

thank you !

I'm missing BIOS files. I found a link ( https://github.com/Abdess/retroarch_system/releases/ ) to complete packs, I assume I'd use the Libreto pack?
How do I know which romsets to use for this emulator?
How can I customize the splash screen?
Thanks to everyone working on this!!!

[Slaminger]

To customize splash you replace the files in /usr/local/bin

Yes the retroarch pack will work, and yes you can put them in sd bios folder. Then run retrorun linker from settings. The only bios you need is Saturn in /opt/libretro/yabasanshiro if you want to use retrorun. Otherwise all on SD.

We finally got portmaster running. Hopefully it will be ready to go for the next release!

[Slaminger]

Update! Portmaster is working along with thememaster and will be in the next release, along with a few other additions. I had my son December 30th, his name is Simon. This is the reason for my temporary absence, but I'm slowly getting back to work on things now.

[Stephen_m64]

It has been an interesting project getting these working, Hopefully people will enjoy the new features.

[animeware]

upcoming 2.3.7 build is coming soon it will have
Portmaster according to slaminger.

I have a question about 2.3.6.

It's about PC88(QUASI88).
About BIOS, it did not work with the following BIOS that worked with Retroarch (on PC), RetroPie, Batocera, etc.

N88.ROM
N88EXT1.ROM
N88EXT3.ROM
N88SUB.ROM
N88EXT0.ROM
N88EXT2.ROM
N88N.ROM

Checking the log, the requested BIOS has a different name
It seems that the file name must be for lr-quasi88.

Code: Select all

[libretro INFO] [QUASI88]: Loaded n88.rom from system_dir (0x00008000)
[libretro ERROR] [QUASI88]: Couldn't find n88_0.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88_1.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88_2.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88_3.rom in system_dir
[libretro INFO] [QUASI88]: Loaded n88n.rom from system_dir (0x00008000)
[libretro ERROR] [QUASI88]: Couldn't find disk.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88knj1.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88knj2.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find n88jisho.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find font.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find font2.rom in system_dir
[libretro ERROR] [QUASI88]: Couldn't find font3.rom in system_dir

Is it implemented differently for RA's PC88 than for the regular Retroarch?

Also, when I change the file name to the one for lr-quasi88 and load the PC88 core, normally from the Retroarch menu "Subsystem", I should be able to select up to 6-disk configurations, but Retroarch on RA only allows me to select 2-disk configurations.

Could you please confirm the above?

I can't get it to recognize CHD (and m3u for multi-CD games) files for PSX. It loads CHDs for PC Engine CD just fine. What do I need to change?

[nickca]

Solving my own problem: we need to change /etc/emulationstation/es_systems.cfg so the "psx" section looks like this:

<system>
<name>pcsx_rearmed</name>
<fullname>Sony PlayStation</fullname>
<path>/roms/psx/</path>
<extension>.m3u .M3U .chd .CHD .bin .BIN .pbp .PBP</extension>
<command>/usr/local/bin/retroarch -L /home/odroid/.config/retroarch/cores/pcsx_rearmed_libretro.so %ROM%</command>
<platform>psx</platform>
<theme>psx</theme>
</system>

If you notice I've added ".m3u .M3U .chd .CHD". However, this file isn't directly exposed over MTP, but we can get at it through the file manager.

You need to do this (and this is also just a general tutorial for interacting with the filesystem):
Open the file manager and copy /etc/emulationstation/es_systems.cfg
Paste it in /home/odroid
Now we can get at it over MTP, as root:
# apt install jmtpfs
# jmtpfs /mnt

Now you should have something like /mnt/ODroid Go Ultra (I don't have it mounted right now to get the exact thing, but it will look like that). Edit /mnt/ODroid Go Ultra/Home/es_systems.cfg and make the necessary changes.
Now you need to copy that back to /etc/emulationstation. Delete the original /etc/emulationstation/es_systems.cfg and paste the new one in place.

Now it should scan and load you CHD/M3U Playstation games! Please consider adding this to the releases!!! The best thing to do would be to just use RetroPie's es_systems.cfg.

With that out of the way, though, I have another problem: USB just flat out doesn't work. My USB WiFi dongle doesn't even turn on. Even a simple keyboard won't work, it seems the port is completely disabled. What's going on there, is there something I need to do?

[nickca]

Dolphin will not work at all (and GameCube and Wii need to be added to es_systems.cfg manually as I described above). The output:

No X11 display found
No platform found, or failed to initialize

Strange! Mine is working flawlessly…
Can you paste your es_systems.cfg GameCube section?
