Belowis the full transcript of my discussion with probono about getting an RA AppImage to run on OpenELEC, LibreELEC or OpenPHT Embedded. tldr: He thinks that someone will need to compile RA on LE. Iāll try this but honestly I donāt even know if that is possible, or, how to even do it. 
[07:49] ==johnodon [4b617b7b@gateway/web/freenode/ip.75.97.123.123] has joined #appimage[07:50] <johnodon> Hello. I was directed here with my question
[07:50] <johnodon> will AppImage run on JEOS distros like OpenELEC, LibreELEC or OpenPHT Embedded?
[07:51] <johnodon> I am trying to run the latest Retroarch AppImage (https://bintray.com/probono/AppImages/RetroArch#files) on OpenPHT Embedded 1.7.1
[07:51] <[COLOR=red]probono> hi johnodon[/COLOR]
[07:51] <probono> i have not tried that
[07:51] <probono> it depends on 2 things:
[07:51] <probono> 1. is FUSE installed on the target system
[07:52] <probono> 2. is the AppImage you are trying to run depending on something that is not bundled inside the AppImage
[07:52] <probono> both should be possible to make work
[07:52] <[COLOR=red]probono> but I have not tried it yet johnodon[/COLOR]
[07:52] <johnodon> This is the error I receive when running the latest RA AppImageā¦
[07:52] <johnodon> ./bin//retroarch.wrapper: line 39: syntax error: unexpected ā(ā
[07:52] <probono> ooops. is bash installed?
[07:52] <probono> or just busybox?
[07:52] <johnodon> I am able to run bash scripts
[07:52] <probono> well that error message says that the AppImage is actually running
[07:53] <probono> just a bash script inside the AppImage is erroring out
[07:53] <johnodon> ok
[07:53] <probono> namely, bin/retroarch.wrapper
[07:53] <probono> which is actually excellent news
[07:53] <probono> because it is a proof that AppImage itself is working
[07:53] <probono> just what is inside this particular AppImage may need some tweaking
[07:53] <probono> which system are you running this on?
[07:54] <johnodon> OpenPHT Embedded Generic 1.7.1
[07:54] <johnodon> iāll get a link
[07:55] <johnodon> https://github.com/RasPlex/OpenPHT-Embedded
[07:55] <johnodon> actually, this
[07:55] <johnodon> https://github.com/RasPlex/OpenPHT/releases
[07:56] <johnodon> OpenPHT-Embedded-1.7.1.137-b604995c-Generic.x86_64.img.gz
[07:56] <probono> wow, didnāt know of this one
[07:56] <johnodon> itās awesome
[07:56] <probono> anyhow, you can do the following:
[07:56] <johnodon> basically LibreELEC + Plex
[07:57] <probono> ./your.AppImage āappimage-offset
[07:57] <probono> sudo mount ./your.AppImage -o loop,offset=XXXXXXX /mnt
[07:57] <probono> edit /mnt/*.desktop
[07:57] <probono> remove in the Exec= line the .wrapper suffix
[07:57] <probono> then run /mnt/AppRun
[07:57] <probono> and see if it works
[07:57] <probono> possibly it will be missing some libs
[07:58] <johnodon> okā¦will need to try later when home
[07:58] <johnodon> I took notes and will report back
[07:58] <probono> ok. cool, thanks
[07:58] <probono> in any case, if it doesnāt work out of the box it can be made work
[07:59] <johnodon> that we be awesome! I love the JEOS media center apps but installing 3rd party apps is a challenge
[07:59] <probono> yes
[07:59] <probono> might be a good use case for AppImage
[07:59] <johnodon> would be perfect solution
[08:12] <Calinou> hi probono
[08:12] <probono> hi Calinou
[08:17] <johnodon> probonoā¦I remoted into home and trying this now
[08:17] <johnodon> <probono> sudo mount ./your.AppImage -o loop,offset=XXXXXXX /mnt
[08:17] <johnodon> what do I use for offset?
[08:17] <johnodon> not xxxxxx I assume
[08:17] <probono> whatever ./your.AppImage āappimage-offset gives you
[08:17] <johnodon> I got same error
[08:17] <probono> then try without an offset
[08:17] <johnodon> OpenPHT-Embedded:~/retroarch # ./RetroArch-1.3.6+r487.glibc2.17-x86_64.AppImage āappimage-offset ./bin//retroarch.wrapper: line 39: syntax error: unexpected ā(ā
[08:18] <johnodon> ok
[08:18] <probono> sudo mount ./your.AppImage -o loop
[08:19] <johnodon> okā¦two things just so you are awareā¦
[08:19] <johnodon> there is no sudo with OE, LE or OPHT
[08:19] <johnodon> so I donāt need that
[08:19] <johnodon> alsoā¦
[08:20] <johnodon> filesystem in read-only so I try to mount to /storage/mnt
[08:20] <johnodon> OpenPHT-Embedded:~/retroarch # mount ./RetroArch-1.3.6+r487.glibc2.17-x86_64.AppImage -o loop /storage/mnt
[08:20] <johnodon> mount: mounting /dev/loop1 on /storage/mnt failed: Invalid argument
[08:21] <probono> you are sure you had typed --appimage-offset with two dashes in the beginning?
[08:21] <probono> i think the chat program changed these into a long ā
[08:22] <johnodon> lol
[08:22] <johnodon> you are right
[08:22] <johnodon> sec
[08:23] <johnodon> 112664
[08:23] <johnodon> okā¦now to try to mount
[08:24] <probono> good
[08:24] <johnodon> mount ./RetroArch-1.3.6+r487.glibc2.17-x86_64.AppImage -o loop,offset=112664 /storage/mnt
[08:25] <johnodon> mount: mounting /dev/loop1 on /storage/mnt failed: Invalid argument
[08:26] <probono> mount -o loop,offset=112664 ./RetroArch-1.3.6+r487.glibc2.17-x86_64.AppImage /storage/mnt
[08:27] <johnodon> same error
[08:27] * probono suspects you donāt have bashā¦ but something like busybox
[08:27] <probono> ok now for the brute force:
[08:27] <johnodon> I beleive that is the case
[08:27] <probono> ./RetroArch-1.3.6+r487.glibc2.17-x86_64.AppImage --appimage-extract
[08:27] <probono> this may or may not work (still a bit buggy)
[08:28] <probono> nano ./squashfs-root/*desktop
[08:28] <probono> ā> edit the Exec= line, remove the .wrapper
[08:28] <probono> then
[08:28] <probono> ./squashfs-root/AppRun
[08:29] <johnodon> OpenPHT-Embedded:~/retroarch # ./squashfs-root/AppRun
[08:29] <johnodon> Segmentation fault (core dumped)
[08:30] <johnodon> guess that isnāt much help
[08:32] <probono> probably the ingredients that went into this AppImage are not suitable for your OS
[08:32] <probono> but AppImage itself appears to be working
[08:33] <probono> probably one should compile RetroArch for LibreELEC and put that into an AppImageā¦
