I had that happen once after an update. I had to tell it to uninstall retropie and then reinstall it. it all worked fine after that.

I can confirm it was the SD card. I bought a new one and made all updates. After that everything runs as intended. :)

PS: I buyed a more expensive SanDisk Extreme. Much faster than the SanDisk Ultra I had before!

@fnkngrv if you update it will wipe the old file and install a new one on the new location.

Nevermind I forgot the bin files >.<

This site is getting cluttered with posts that end with a reference to the rules. It would be nice if they were deleted by the administrator that ended the discussion or linked to the duplicate/repost.

Thanks to all for the advice. I have used the no intro rom set and slimmed it down to English language only games using Romulus and a dat file from dat-o-matic.

@BuZz , have you read this topic to fix the controller on the future Retropie Update ?
For the screen i'm sad but i don't found why it's not working fine :(
Thanks

@wombat Update, then everything is now set up for KIOSK mode.

After using ClrMamePro and updating my ROM set... and finding out that i didn't have to go through all of that....
i already had the correct ROM set version. All i had to do was copy over dkong.zip and then ReStart EmulationStation.
Donkey Kong showed up and played just fine after that. Thanks for all the Great Advice.!!!!!

@ballboff I tried what you mentioned but nothing shows up but the same 2 options:
0
H hidden ESSID

I honestly don't think its something that simple. I logged in to my router to see if it would even pick up the Pi, unfortunately it's not.
Thanks for your input, I appreciate ALL the help I can get.

I checked in my network to see if the Pi would show up but it does not. Either way I get no wifi regardless on the PiZero W. In regards to the GBA, I forgot how the frame rates were on it lol but it seems to be normal. I will check up on a few more Roms on the SNES when I get back home to confirm if it's only a few games being affected.
Thanks for your input

@gpr17 4.1 is not the latest version, but I've not tested this on OSMC. I will need a complete build log to see the failure. I would recommend you use the last RetroPie image if you wish to use the experimental modules.

Doh! I did read the documentation but overlooked this. I checked it again after your answer and you're right, it's definitively there. Sorry, my bad.

If you have the files, then you could run them under dosbox.
Such as, if you had the files to run I dunno, Jazz Jackrabbit. You could run it on DosBox.

You don't necessarily have to rename all the files. If you use UXS it will scrape all the cover art and also create a gamelist.xml. That XML file should contain the proper meta data for your roms in it, which is what emulation station displays...

Yes..you can expand the filesystem in Raspi Config in the Retropie menu.Then the additional space will be seen and used.

The Problem was located:
When using pbp files with sbi files the extension both must be lower or uppercase.
Having them mixed will result in the emulator not finding the sbi file since linux systems are casesensitve.

multidisc PBP Systax is as described in the sourcecode comment above.
