Which software project is "help me delete this shit" - exactly?
Oh I know, its an emulator. No...
Homebrew perhaps? How about you homebrew yourself to the correct thread or forum then?
How about you name applications?
How about you do anything apart - tell a story with "now YOU solve this sh*t" at the end.
Answer is: You probably cant easily. Get a working whatever of the thing you wanted installed installed. Installs usually have the same folder names, so the thing already there should be overwritten. Or restore a Nand Backup. Or perhaps, use more complex (PC based) tools I've never used, to wipe your system storage partition in place. People that would walk you through that, because you "want to get rid of shit" probably aren readily available though Also - I wouldnt watch youtube videos on this.
Let me rephrase that. I wouldnt ever, for the life of me, watch youtube tech tutorials on anything. (Well, one time I did repair a dishwasher...)
edit: Factory reset should do it as well.
