Recently I aquired a brand new copy of metroid for FDS and at first it worked fine but today it started it acting funny. There was a glitch where sometimes it would save with morph ball ability not working and the game registering with it already aquired and have to delete my save file and start all over again.
But today I started getting read error 01 twice today then when I loaded the game save file was gone after happening 2nd time. My question is is my copy of metroid corrupted or is it an issue with my FDS or a common glitch in the game? Cause after everything erased it seemed fine.
