Continuity: In every gym there is a statue that lists the names of all the people who have won there. The only names that appear are the player character's and their rival's, but when you go to the elite four there are all these other trainers. How did they get past the guards when they don't have any badges?

Audio problem: When your Pokemon is low on health it makes a beeping noise. This noise can interfere with Pokemon cries and attack noises (i.e. Kadabra's cry sounds like Ghastly's cry).

Other: Go to the item list, and select any HM. Attempt to use it in a Pokemon. Before you do, the text below will say "Use TM in which Pokemon?". However, you are attempting to use a HM, not a TM, in a Pokemon.
