The level script in the Pokemon Centre is terrible, you go in, and it's a map that has another computer in it, but you warp into another pokemon centre with no room in it, there is grass in front of the water in the beggining forest and it doesn't have the brown bit behind it, officer jenny walks on top of you when she moves away from Elms lab, she is standing behind team rocket when there is no possible way she could've done that, Brock and Misty teleport all the time instead of walking away, Team Rockets sprte is glitchy and incorrectly inserted, the font is corrputed, and there is probably more but I haven't gotten further yet.
