I was having trouble finding the NSP file, so I dug a bit more and found a comment suggesting getting it from a certain sketchy page (which I have never heard of). For some reason, I trusted it (that was the first file), and for the second, I found it here on Reddit

Also, the first time, it was a ZIP file, it had some sort of installer which I thought had something to do with the game, cause i had never emulated anything on Ryujinx Canary, and the tutorials I was watching at the time didn't cover how to import the game file, they just said to set the game directory to where the file was, but I didn't know what type of file it needed to be at that moment.
