that 8th badge was so rediculous. really challenging trainers in the last gym.
I have seen quite a few bugs throughout the game:
near articuno are several spaces you cant walk on, even though you should be able to
girl who teaches blast burn etc. wont teach it to me now after i changed my mind and canceled out
jumps in last gym can make you land on rocks, shouldnt be able to walk there.
Some of the caves lets you walk on rocks, i found some near the strength boulders letting me not use the HM sometimes
all across the game, each wild pokemon is very specific (ie. Jynx is always level 48, shellgon is always level 56, machop is always level 45 etc.)
in last gym, some guy at the top right says training is "tense", should be intense
theres a few more minor ones but i cant remember off the top of my head.
Im at the elite four but i need to train a lot before i can beat them all in a row.
Anyone know how to get the coin case?
