The Odroid Go Advance/Super/Ultra

There are currently two work in progress builds of Retro Arena available for the Odroid Go Ultra.

 OGU TheRA with Retroarch:

This is a build with a full RetroArch GUI, armhf and aarch64. Sega Saturn, Dreamcast, Naomi, Atomiswave use RetroRun from crashoverride, and N64 uses Mupen stand alone. NTFS and ExFat sd2 formats are supported, and a roms skeleton folder structure is provided inside of the zip for your SD2, it will auto mount at boot. Bios also go on SD2 into the bios folder, your roms folders should be located at the root of the card, not in a sub folder. It currently has 106 different systems emulated.

The bottom left grey key will exit RetroArch, bottom right will open the menu. The two circular buttons are select and start. 

To exit Daphne/American Laser Games use F1 and F3, F1 being the bottom left grey button.

Flycast, and Yabasanshiro via RetroRun require your bios in /opt/libretro/flycast or yabause

As of RC 2.3.8 OTA Updater, Portmaster, Thememaster, and working bluetooth, including the Hardkernel all in one Wifi/BT adapter. No audio currently, but controllers work.

Please use the forum link below for more detailed information, and read the change log. 

OGU Stock Mod:

This is the current stock firmware, but it has 75 systems supported. This build lacks the RetroArch GUI, however it has a more simplistic and straighter forward setup, simply place bios into /opt/libretro into the corresponding core folder and the best settings are already selected for you. This build supports NTFS and ExFat SD2 and will auto mount at boot, a zip file for the rom folder structure is provided inside of the zip.

Both builds have been modified to not ask for a sudo password, and both have a su password of odroid. The login and password remain odroid.

More updates for these builds will be coming in the near future.

 Retro Arena for OGU Development Thread - ODROID 

Older models, scroll down.

Over time, we have been working very hard to  maintain a build of Retro Arena  for  the Odroid Go Super and Odroid Go Advance. I am happy to say we remain successful in our endeavors and are able to provide users with a new OGA/OGS RC5.2.1 as of 2021-10-03

**Please note, at first boot your handheld will restart twice, this is normal. It is resizing your NTFS /roms partition to fill the SD card you used. Use larger than 16GB or you will have no space left over.

* OTA Updater has been added.

*RetroArch updated to 1.9.8 as of RC 5.

*There is now an over the air theme and ports downloader located in tools.

This release is built on Ubuntu 20, and has about 110 systems set up to launch through EmulationStation, as well as numerous cores that can be used via RetroArch directly. Tiger and Konami LCD games, along with Daphne Laserdisc have been added. Both EmulationStation and RetroArch have been rebuilt to work on all models of OGA/OGS. This is a new version of EmulationStation shown to me by Christian, and it can scrape 2d, 3d, screenshots, and videos. Video screensavers and video snaps are also now working on all models. 

*You can change scaling options by opening  RetroArch and go to Options > Video > Scaling and switch the ratio to 480 x 320.

*Do not delete the MPV.py script in the videos folder, or you will lose the ability to play movies and shows. 

*If you have an issue with games not scraping, scrape a game with thegamesdb first to generate the folders, then switch to screenscraper to scrape 3d box art and videos.

*Ports have been added, for Doom you must place your .wad files at /roms/doom

For CannonBall(Outrun) you must place the files at /home/odroid/.config/retroarch/downloads into the CannonBall folder, a file in that folder will tell you what you need.

*The other ports are shareware made by non commercial developers or are abandoned, so we did not remove their files. Lutro and Chailove are also shareware open source projects.

*For users having trouble with bluetooth:

sudo apt-get install bluez-tools

sudo service bluetooth start

and successfully connect to it and get mac

sudo bluetoothctl

[bluetooth] agent on

[bluetooth] default-agent

[bluetooth] scan on

[bluetooth] devices

[bluetooth] pair <bluetooth_mac_address>

A new version of EmulationStation  has been installed, and a new kernel has been installed that allows overclocking up to 1.5GHz, further information can be found in the ReadMe and below.

**Format your SD card to NTFS in Disk Management, delete each partition one by one until the whole card says unallocated. Then right click it and click format. Do this before you flash the image to it, or it might fail.

***if you are using oga please follow these steps to restore mpv and sld2 functionality. 

download the zip in this link libSDL2-2.0.so.0.14.zip

unzip it onto your pc, turn your device on and connect to the internet.

open winscp and log in to your unit, navigate to /usr/lib/aarch64-linux-gnu. open a putty ssh connection and run sudo chmod -R 777 /usr/lib/aarch64-linux-gnu. now drag and drop the file from the zip in, and locate the libsdl2.so.0 file located in the same area, right click it and select edit link, change it from the current version, which is 0.10 to the new one 0.4 and make sure the name matchs identically. once this finishes you may close winscp, before you close putty run sudo chmod -R 755 /usr/lib/aarch64-linux-gnu.

now type sudo reboot, upon reboot you may now use mpv, drastic, and the sdl based ports on OGA. 

***Overclocking:

Here is The Retro Arena RC 2.6.1 Beta for the Odroid Go Advance, this release resolves the joystick issue with N64 and PSP, as well as enables PS1, SNES, NES, Genesis/Megadrive and Dreamcast to use the new two player mode from crashoverride.

This is a Beta, as such bugs are to be expected. The release is intended to get feedback from the community to fix any remaining bugs or issues before the final version.

Nintendo DS has been temporarily removed as it is having issues, and will be added back later. 

Please not that for Dreamcast, Naomi, Atomiswave, and PSX the bios go with the cores in /opt/libretro, and for the rest they go to /roms/bios. 

Please be advised two player mode is in early development stages and has some bugs still, if using this image for a model 1 OGA you need to use Retroarch and Retroarch32 and go to input and rebind the controller.

A mostly complete system list:

Arcade/FBNeo, Dreamcast, Atomiswave, Naomi, Sega Saturn, Neo Geo, CPS 1 2 and 3, MAME, Famicom, Famicom Disk System, Virtual Boy, Super Famicom, Sufami Turbo, Snes MSU1, SNES, the Snes-hacks folder is for games like Yoshi's island with a special chip in it, intellivision, N64, N64DD, Gameboy, Gameboy Color, Gameboy Advance, PlayStation 1, PSP, PSP Minis, Sega Master System,  Sega CD, Mega Drive, Sega 32x, Game Gear, Neo Geo Pocket, Neo Geo Pocket Color, TurboGrafx 16, TurboGrafx CD, PC Engine, PC Engine CD, Supergrafx, NEC-PC98, Vectrex, Wonderswan, Wonderswan Color, Atari 2600, 5200, 800, 7800, Lynx, MSX 1 and 2, DosBox, Coleco, Sharp X1, Scumm VM, Commodore 64, Nintendo DS, Vectrex.

I have included RetroRoller from Valadaa48, which basically installs Retroarch into the build via a debian package that supports rolling updates. Because of this the majority of emulators now have the Retroarch menu and the settings and customization options that go with it. Also with the exception of Dreamcast and Saturn all bios now go into /roms/bios  as of RC 2.4. Flycast and Yabasanshiro are the only bios needed in the /opt/libretro folder in with the core. 

keyboard based games require you to remap the key layout in Retroarch or connect a USB or wireless keyboard. 

Release Candidate 2.5 (temporary) is available as of 06/06/2020.

This is based on Arch Linux, still has RetroRoller from Valadaa48, and all the things the previous build had, there are some differences as this image is not finalized yet. To connect to wifi navigate to the sd card after the image is written to it(while it is still in your pc), open network.sh an fill in your ssid and password. The GUI from RC 2.4 for network connection is still being ported. Also the Drastic button layout is broken until next week, and you will be able to drag and drop the fix in, it will only work on model 1 currently.

When using Dreamcast, Naomi and Atomiswave press F3 + F1 to exit or it might hang for a few seconds if only pressing F1. and ScummVM must be launched from Retroarch. 

to see your IP click on the Retroarch logo inside of es then click Retrolauncher, click Emulationstation to return.

F3 is the global hotkey on this release. 

To expand your sd once you have connected wifi, use Putty to ssh connect and then enter sudo systemctl start firstboot.

The Ubuntu image is RC 2.4 with the kernel and uboot from Ubuntu 20 backported so that wifi and l2 r2 work. If you use this image in model 1 you need to remap your controller in es and retroarch, you will also need to swap the drastic config depending what version of OGA you are using.

Drastic will work on model 1, but for OGA-BE please click the ubuntu link below and grab the config files, place them into /opt/drastic/config

***For Ubuntu RC 2.5 when you first boot, connect to wifi, use ssh to connect to the device and type sudo ./resize.sh and follow the instructions, this will resize your image to fill the sd,  the default size is 16GB. 

If you wish to enable the joystick for Retroarch games press f3+f4 to open the menu, navigate to input,  port 1 binds, then set analog to digital type to left analog. 

**If you have any issues with the sleep function open a ssh connection and type sudo nano /etc/systemd/logind.conf and scroll down the the line saying Power=Ignore and add a # at the start of the line, this will disable the sleep function until it is resolved.

The page below will let you know what bios is needed for which core:

https://retropie.org.uk/docs/Supported-Systems/

For version RC2.4:

This build incorporates the base image from Crashoverride, meaning Ubuntu has been updated from 18 to 19.
Sega Dreamcast, Naomi, Atomiswave, Dos, Commodore 64, Sega Saturn, NDS and a couple other systems have been added.
The themes by Travis Wilson have been updated to include the new systems and Retroarch. Also Mame cores by the year have been added.
Retro Roller from Valadaa48 has been added, this integrates a full Retroarch into the build and that has been added to the theme as well, both 64 and 32 bit Retroarch are included.
Most of the emus that were cores have been moved to Retroarch to allow use of the Retroarch menu. The bios for all of these now belong in /roms/bios
The exceptions that do not use Retro Roller are:

Dreamcast, PSP, N64, ScummVM, and blue Msx for Msx 1 and 2. Coleco uses Retroarch.  These bios still go into /opt/libretro (saturn and dc only) into their respective core folders. While the rest now all go into one folder as noted above.
The sleep kernel function as also been added, tapping power once is sleep, holding it down is power off.  

Snes9x_2002 and Snes9x_2005 32 bit cores have been added, along with Parallel N64 both 32 and 64 bit cores, to Retroarch directly. When you launch the n64 core you must enter the Retroarch menu and change the gfx plugin from auto to rice for proper playback.

When using Drastic for DS the f1 key brings up the menu, its a bit buggy in the sense sometimes it stays black. if you tap the dpad a couple of times it pops up. To full screen a game, go into the menu and options, change screen orientation to tingle. Now the main screen is full screen. F3 will swap between screens. When playing in 2 screen mode you can use the f key to swap the positioning of the screens to make the picture larger. 

Edit: the Drastic menu has been fixed. please redownload RC 2.4 correct the bug.

 to change the language to English in Drastic, edit: /opt/drastic/config/drastic.cfg

firmware.language = 5 to firmware.language = 1 

Please note Saturn and Dreamcast function like n64, not all titles are playable.

I would like to thank Crashoverride, Kamots and their team of community developers for  their base image and continuous contributions to this device and the Odroid community. 

Also, Travis Wilson for the beautiful custom made Odroid Go Advance themes.

And Valadaa48 for his creation of  Retro Roller.

Along with the Lakka Team, especially Demetris and Natinusala.

NoirBright for the hotkey functions, and photo to go with them.

ETAPrime for his videos and support of the build,  it is greatly appreciated.  

This project is dedicated to the memory of my grandfather Rudolf Laminger, Born December 16, 1934 and passed away November 24th, 2019. My grandfather was very proud of me and the work I do, the happiness and nostalgia it brought to others,  and I was very proud to have spent 33 wonderful years learning from him. He always taught me to follow my heart, and that is why I started Tech Toy Tinker. I hope you all truly enjoy this device and retro gaming as much as I do.
