Sorry I never noticed anything wrong with the GBA version that wasn't wrong with the original back when I played both of them 10 years ago. I assume someone somehow found Missingno in the GBA port once they got at least 3 Chaos Emeralds? The most I was ever able to get in a single run was 2 of them because Sonic 1 has the worst special stages.
