Hello, I just got a FDS and 3 games to play on it. 2 of the games work without any issue (Zelda and SD Gundam World: Gachapon Senshi), but the 3rd game, Metroid, gives me an error 27. Looking on the forum, that seems to be an alignment issue, but if my drive is misaligned would I only be getting an error on one game?
It's officially a CRC error, but this (https://www.famicomworld.com/forum/index.php?topic=7142.msg185830#msg185830) is my take on these errors.
If you are in the US (even if you are not, but shipping will cost more than its worth) I can re-write the disk for you if you pay the shipping.
If you have the card cleaner that was from Nintendo, that might work, if you cleaned the disk.
