@Fastcat4 First off, I appreciate people being new to these and not getting their heads around it. However, the info we asked for, and guides and wiki we pointed you towards are all in the stickied "read this first post" at the top of every page of the forum.

This includes all links to the RetroPie wiki which we have been directing you towards.

It also has a table in it to copy and paste to provide accurate details as to your setup and build.

I don't believe you have read that post nor the wiki anything past a cursory glance.

As before, I diagnose a corrupt SD card. I'd check for a compatible card (use Google to find the list), buy it, then read and follow the wiki to try and rebuild.

Never pull any memory cards when data may be being written to it. This applies for all devices, not just raspberry pis.
