So, I am working on a bunch of Generation III hacks to make them a little better without taking away the original structure of the games, so far this is what I am planning to do.

>Rare pokemon become uncommon, uncommon pokemon become more common, super common pokemon become just common.
>TMs can be purchased, berries can be purchased.
>Special event flags can be set and reset to be able to continually recapture legendary pokemon and the like.
>Move tutors are now infinite and some of them relocated (no more Rock Tunnel Rock Slide.)
>Revamped evolutions to be able to have them on single player (ie. Alakazam)
>Version exclusives are still exclusive though.
>Some useful items can be purchased (Ether and Masterballs.)
>Some random items are replaced for better stuff (no more X Attacks on the floor and so on)

Any other suggestions?
