Complete noob please help

I bought a raspberry pi 4 off of my teacher and he had a bunch of penny bs games that no one would ever play so i deleted them but now i want to add my own games. i bought a sd card to usb 3.0 and its filled with dtb files and elf files and kernels i dont want to bomb my computer but how do i add my own games. Yes i did read the Read this first. but i dont know what any of that stuff means/is.(i attached a picture so if someone knows what to do can help) Also if in wrong subforum let me know will move it happily. image url)

@jorgejohnson72 When i click on a kernel it says the file is corrupted. but the pi runs just fine

You have to boot up the pi, and use a local connection or usb to transfer roms.
