This is a great romhack! The increased difficulty, all pokemon up to gen 4 availabe, and the rebalancing of weaker pokemon made this my preferred way to play the Johto games. My only major issue with the game is that the Kanto half of the game is very easy compared to the Johto half. The Kanto gym leaders had basic teams that had predominantly no items outside of a sitrus berry. I wish that they were made harder. The rematches were good, though.
