Drayano's hacks (Sacred Gold, Storm Silver, Blaze Black, Volt White, Blaze Black 2, Volt White 2) are probably the best out there in terms of quality. They make the games much more fun and challenging. But they are pretty standard self-contained hacks. There are some hacks out there that completely change the story of the games, but many of them aren't too great. Drayano also helped me make Origin Platinum, but Mt. Coronet and the post-game are riddled with bugs that I have been either unable to fix, or haven't had the time to fix. Flawless platinum is another self-contained Platinum hack.
