Come and get it folks - PKMDS Desktop is now ready for use! Currently editing of Pokémon and changing the current box are the only real features. Importing, exporting, and removing Pokémon is next, probably closely followed by moving Pokémon around in the boxes and party.
NOTE: After thorough (and needlessly arduous) testing with the retail games, I can say that this application is correctly writing data to the save files and updating the checksums as necessary. However, feel free to inform me of any bugs encountered.
Also, you'll notice Ribbons are not yet implemented, there are no contest stats (does anyone care?), and the Misc. tab only contains a read-only PID for now. This application is still in-progress, mind you.
Get it while it's hot - https://www.dropbox.com/s/gt5rgv80rj72ajq/PKMDS%20Desktop%20-%20Qt.zip
