I have the same issue and cannot seem to find a solution anywhere, hopefully someone will see both of our s.o.s messages and send help.

Thanks for your help, I wrote that in command and got the following:
ln: '/home/pi/pimame/roms/mame4all': hard line not allowed for directory

I went into desktop and used file manager to look in the mame4all-pi folder and it is empty, is this normal? it seems like the mame4all emulator never installed.

Thanks,

I tried that and still no luck, I have cleaned the SD card and re-written the image to it.

I was wondering if you could give me a bit of a guide as to how what I should be doing including what to write in the command line. This is about the 5th time I have had to start again, and I am starting to think it might be me :)

If you could assume I don't know anything about linux, which is 100% true.
I will understand if this is too time consuming for you, I appreciate your help to date.

I have just made an awesome arcade gamepad, and all that is missing is a small machine that can run the arcade emulators and roms, hopefully if you can help I will be able to complete it and upload the photos of it all up and running!

Thanks,

Bryce.

I'm also having similar issues.
After running the line above, I get the message that the files were already linked.
"ln: failed to create symbolic link '/home/pi/emulators/mame4all-pi/roms/mame4all': File exists"

I'll check it out when I get home tonight. Thanks.

I ran this:
rm -r /home/pi/pimame/roms/MAME4ALL
ln -s /home/pi/pimame/roms/mame4all /home/pi/pimame/emulators/mame4all-pi/roms

And got the same error as listed above

yes. sorry, I did.

Try running:

rm /home/pi/emulators/mame4all-pi/roms/mame4all

And then run this again:

rm -r /home/pi/pimame/roms/mame4all
ln -s /home/pi/pimame/roms/mame4all /home/pi/pimame/emulators/mame4all-pi/roms

Maybe it's a problem in your MAME.CFG file?
Have a look where the roms section of that is pointing too.

nano/home/pi/pimame/emulators/mame4all-pi/mame.cfg

Sorry it took a while to reply, because I posted twice in 60 seconds, Spam Block is now effective on my account, apparently. (ಠ_ಠ) I've had enough time to even look up Eastern Emoticons. ¯\_(ツ)_/¯ Yay

Nice emoticons! And don't worry... it was late where I was and tried to go to bed...
Huh. Now *THAT'S* weird... that file, mame.cfg, is blank. Like, empty. I'd expect there something to be there.

I think if you reimaged or re-run the mame4all jnstaller plus create the symbolic link, it may work. Try going into startx and deleting mame4all-pi and reinstall mame.
I dont know, sorry.

Edit config.yaml and change 'Install Mame' to visible. Then load the menu and run the installer.
Once its finished you may have to make mame4all visible again in config.yaml

hi all ... i had same problem and solved , it's not a bug .. it's easy .
you need to extend the FS. and reinstall mame4all-pi .

go to the shell (exit)
type "df" if you see /rootfs or /dev/root to 98% you are running out of space and the installation script fail becasue no space on sd.

run sudo raspi-config and extend the SD FS (first option)
reboot
go to the shell (exit)
reinstall mame using the script located in /home/pi/mame python mame_install.py
end...

Havin' the same problem! Sure enough my /rootfs (not sure what that means!) and the other one were at 99%. So I got rid of the wolfram-engine. Now they are at 84%. So now I'm stumped at reinstalling mame4all. I'm not totally understanding the "reinstall mame using the script located in /home/pi/mame python mame_install.py" that was mentioned above. I mean, I found the text that is in mame_install.py but I have no idea what to do with it or what it means! Any way to dumb it down or am I hopeless?!?

Not exactly sure what that means to expand the rootfs. I did try reinstalling pimame with the script you gave me. It worked in that I reinstalled mame4all but then when I tried to open it up I got a new error message. Ugh! Frustrating...

Thanks kris, I could finally install mame4all.
Great work!
