Well have fun! However, bare in mind that I released that way back when the games were released in Japan, (September 2009) so it only works on the Japanese Versions sadly. Plus I lost all my sources so there's no chance it'll be updated soon... I'm planning to re-write most of my tools in a new cross platform language though, so i should be releasing more cool stuff soon :)
Hey! Thanks very much :) I decided after two years of being away I'd come back with a few updates and fix up the Swampert Tools website. I only just realised what a good resource it is to hackers :)
