I have investigated and you appear to be right, I have already found the issue and have fixed it. I am planning on updating the game later today with this fix and a few other things. Thanks again for reporting this :D
Sideloading now! If you didn't have any other games that used the default file names, it would work fine on yours. I'm not sure which game on mine was conflicting...I have a bunch. Thanks for fixing it so quickly!
