ORA Retropie image for the odroid Xu4

if you need anyhelp setting up anything go to the Odroid forum. https://forum.odroid.com/index.php
(if it is ok to put links for other forums )

for your basic it works out of them box, but if you want to get older pc games working like Halflife, and jedi kight 2 working it can be a pain.

No i have not used BATOCERA , i have a load with ORA and that also works great and bluetooth works good for my 8bitdo controller.

@exarkuniv Thank for the link. Yes I know BT on ORA is very good. WiFi is a bit tricky because my results with BATOCERA was much better. I hope ORA v2 will hit some gaps, All in all it is a very good image with lots of nice Gimmicks.

OpenBOR for Xu4 would be nice .... Newest version of course maybe someone can port this. As I said it seems just an SDL2 dependency issue

ExarKunIv · 5 Oct 2018, 18:07

@cyperghost
from what i have seen on facebook for ORA, they have improved WiFi they where to drop V2 last week, but something did not compile right so they needed to push it back

i do think OpenBOR will come out. they will just need more time i think they are nailing down all the main systems first then going after the smaller things

ORA 1.5.2 is out
With support for various new emulators and the OGST N64 display ;)

Ryuzaki1986 · 13 Oct 2018, 21:51

So I put the bios where they needed to be and added my roms but Atomiswave and Naomi folders aren't showing on retropie, anyone else had this problem, I can't figure out what I've done wrong.

@reesk92 @ExarKunIv
If you are a owner of the N64 case you can make the left button work

 #!/bin/sh
# by cyperghost
 
[ -z $1 ] && leftswitch=24 || leftswitch=$1
 
echo $leftswitch > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio$leftswitch/direction
 
until [ "$status" = "0" ]; do
    sleep 0.5
    status=$(cat /sys/class/gpio/gpio$leftswitch/value)
    echo "Status: $status - GPIO: $leftswitch"
done
 
echo "I am done! Resetting GPIO $leftswitch now!"
echo $leftswitch > /sys/class/gpio/unexport

It will output 1 if button is not pressed and 0 if button is pressed. So we can kill running emulators or do annother crazy things. GPIO 24 is button key ;) Barly no documents are available so it was a bit try and error. Finally found the little nasty....

EDIT: EXECUTE script with sudo otherwise echo export will fail!
This is just proof of concept! It works of course but gives an entrypoints to other coders outside world - so enjoy!

@cyperghost that is really cool.

The N64 is AFAIK the only gaming case for the odroid. I like the small screen ;)
But the left button (looking from the back wiring!!) is not invoked to any action.
I tested some scripts to terminate emulators - even non libretto ... They can all closed by pressing button ;)

cyperghost · 20 Oct 2018, 12:24

@ExarKunIv Is there a ORA forum?
I removed the display usage out of runcommand and replanted it in the place it should be ... inside ~/ogst/ogst.sh
We can use runcommand-onstart/onend to give script right direction for setup. I think runcommand should be kept untouched ...

@Ryuzaki1986 I'm having the same issue. ""For NAOMIS's roms, you must have two files by game, one .lst and one .bin"" I found this quote on AP but not sure what I need to actually do. Perhaps a different romset? I'm still digging

reesk92 · 21 Oct 2018, 06:42

ok to clear some things up i dont work for the ORA team on a official capacity no longer we cane to a agreement and i just sit in the background and test stuff out from time to time and work on the odd theme i dont own nor work on the ogst case ogst case is owned by odroid and the os ogst is owned and developed by meverick

ill pass on that script suggestion to adrian taur (slappymcphee) for his attention

now discord the new discord is available on the website http://odroidarena.com/

we dont have a forum we simply dont have any real desire to maintain one especially when we cant even get some people to go read the damn wiki to have questions that were already answered answered so what hope do we have that they would check for other forum threads that are the same as there own we have a facebook but were moving away from it to mainly discord because its easier for the developers to answer questions because there in there every day

wifi is the easiest thing on earth to fix just buy pretty much any of the wifi modules from ameridroid they are baked in for compatibility and range from 5 -30 bucks depending on which one you want wed love to make others work but before that happens everyone needs to sit down and agree on what dongles most people use because WE WILL NOT be doing support for every dongle under the sun just because you bought a one hung low dongle off ebay or some obscure website

bluetooth if it says csr 4.0 it will work why because for some reason linux really really likes that dongle and it just works flawlessly so why mess around when its like 10 bucks and lower

2.0 IS TABLED no one is working on it its not even a priority at best someone takes a poke at it every couple weeks but as it stands there is no plans for the time being to release 2.0 it has issues said issues are awaiting fixes and untill then 2.0 is shelved

1.5 is the current release it is a long term release ergo it will be suplimented with over the network updates for a while to keep things moving along without the need to reflash a sd card

@astal79 said in ORA Retropie image for the odroid Xu4:

hello the sega saturn will be presented in the next update for the odroid xu4 a dev has been paid by the community odroid for it works on the compatibility in 32bit on the odroid xu4 how is it that on raspberry while the community is bigger there is nothing?

ill give you the same answer i give my community when they ask this

raspberry pi is not a odroid xu4
odroid xu4 is not a raspberry pi

raspberry pi uses a broadcom chip
odroid uses a exynos chip

to expect one to work like the other is like expecting a stroller to go 90 mph just because it has wheels like a car

if you think your hard done by just remember your a bigger community shit you guys get as standard weve had to fight for to get working because we have a far far smaller community

weve only had the divine blessing of a xu4 compatible build for 1 year and its because of this and the small comunity weve had to work just to get as far as we have

you guys have mehstation and attract mode we do not because it has no recent 32bit compatible build

saturn DS and a couple others didnt even have compatibility we had to raise money to be able to make it worth the developers time and to purchase them hardware so they could develop there emus for us

anyway to summarise like buzz said your not a xu4 your hardware is different theres stuff that simply cant be done

but before you feel sour we cant do things you guys can for the same reason

@reesk92 Changed some scripts and make reset button work proper to terminate emulators and restart ES!

 #!/bin/bash
# Make right button work
#
# if emulator is detected is kills the process
# if no emulator is running ES will be restarted (properly!)

@cyperghost i was wondering what to do with your script, does it go in a startup script somewhere? do you just run it once from a terminal? i am somewhat new to linux and just not completely sure what to do with your script but i really like tge idea. i just bought the OGST n64 case but have yet to set it up

cyperghost · 1 Nov 2018, 05:46

@lordcrammy Edit the autostart with nano /opt/retropie/configs/all/autostart.sh and add line sudo /home/pigaming/button.sh & before the emulationstation call. Then it will work

Change the path and the name of the script as you like but don't forget the &

lordcrammy · 2 Nov 2018, 12:32

@cyperghost thanks! i'll try it out this weekend

cyperghost · 2 Nov 2018, 16:32

@ExarKunIv
Created a script to enable/disable WIFI connection according to this thread posting #2 even the title is a bit misleading (because it is not rfkill) ;)

What is the purpose? Because Wifi and BT interfere together and with a simple toggle dialog you can disable Wifi and BT inputs are lag reduced or even better signal distances ;)

@cyperghost i gave this a try, i love it. works like a charm. thanks for it

This might sound like a stupid question. But would it be possible to port Irata Jaguar and Real3doplayer to the Odroid Retro Arena?

Since both Irata Jaguar and Real3doplayer emulators run perfectly and at proper FPS on Odroid using Android.
