its actually coded quite well for the most part
t romhacker
basically any super popular game can be torn apart to find 17 thousand bugs no one would notice on a playthrough
the only bugs in red/blue people would notice in a playthrough or even encounter really are
1. incorrect dual type attack effectiveness messaging
2. focus energy (if they knew what it was supposed to do)
3. fly/dig+fully paralyzed invulnerability (but since the player is the only one who will use these moves it will be a benefit to them to experience this bug)
