I know it's not done, but for those interested I have made an unofficial white patch that contains everything needed to take a clean pokemon white dump and make it exp patched, logo change, and the current repo's translation. I don't own pokemon black, so I can't make a patch for that at the moment. If anyone wants me to make another for them at a later date, just let me know. THIS IS NOT AN OFFICIAL V4 RELEASE, THIS IS JUST THE CURRENT STATE OF THE PROJECT! POKEMON WHITE CLEAN DUMPS ONLY!
