This is a great hack and I am currently playing it for the second time. Thank you alot for doing this :-)
The only change-worthy thing I noticed so far: The traded Maworak is not obeying me anymore from lvl 30 on. It would be nice if the max level for traded Pokemon could be changed a bit, so you don't run into that areas that easily.
Usually I would have leveld it higher at the electricity-Gym and would use it now for the fire-Gym, where I am currently having some major difficulties.
Another thing just came to my mind. However, that would be a rather major change and might not be in your interest:
Being able to refight the gym-leaders any time you want. That would make grinding a bit easier for people like me, who arent that well with all the tactics and tricks that come into play at that level.
The first one would be nice, the second one is just a spontaneous proposal.
I've never taken the time to learn these things, so I don't know if its even possible.
Thanks again and greetings :-)
