Drayano, I think you've created a great hack here! Being able to catch all 649 Pokemon in one game is any Pokemon player's dream, not having to deal with trading for evolutions, version exclusives, or previous Gen Pokemon. THIS is what a real Pokemon game should be like. If you could actually sell your hack, then I'm sure you'd make a lot of money out of it!
I just started Blaze Black last night and started with Snivy because I got excited at the fact that the final evo will be Grass/Dragon with Contrary! Leaf Storm and Draco Meteor become so broken combined with Contrary >
I haven't looked through all the documentation, so I'm not sure if there's a move list for each Pokemon. I've been thinking about certain moves that could be improved upon to create some balance. For instance, Fire Blast has 85% accuracy, whereas similar moves like Hydro Pump, Gunk Shot, and Gale only have 80%, 70%, and 70% accuracy, respectively. This isn't really fair. Why should Fire Blast have higher accuracy and be able to benefit from Sunny Day?
Healing moves also need a little balancing. Recover and Roost have 10 PP, but Morning Sun, Synthesis, and Moonlight only have 5 PP. Not many people use Morning Sun, Synthesis, and Moonlight, yes, but they shouldn't only have 5 PP when they're not even guaranteed to heal 50% HP like Recover and Roost are.
I have more suggestions like these, but I'm not sure if you're still taking ideas to improve this game or if you're done with it. I'm curious to know if you have the ability to modify type advantages and disadvantages? If you do, then I have suggestions for reworking the type chart, which is something GF really needs to pay attention to for next Gen.
Lastly, I was wondering why you decided to make Pignite and Emboar Fire/Ground and not Fire/Dark. The latter seems to suit them better. I'm not sure if you did anything to the flying bugs that aren't part Flying, but I thought Pokemon like Beedrill, Venemoth, and Volcarona should get an ability called Flight (same effect as Levitate), as it doesn't make sense for them to be able to fly and not be immune to Ground-type attacks. If they got an extra ability to give them flight, then the player can choose whether they prefer Ground immunity or Tinted Lens for Venemoth, for instance.
