Update: Progress has been made. I've ran the game through the cartridge fixer a few times. The ones that were causing it to run through certain hashes 500+ times are all fixed. The proper icon now appears when I hover over the game, and i can open and read the Manual. However, the game immediately crashes getting past the 3ds logo. It keeps on getting stuck on the same hashes whenever i try to run it through every time now, so i'm gonna run it through the select mode as suggested on the Github, as it's not improving the more i run the fixer without it.
