Head on over the the gamecube pokemon hacking discord https://discord.gg/aucXehNbwM to shout at me about anything I might have missed.
 
Must give a massive shoutout to Stars who has helped me throughout this process, and who without his tools I'd have not even managed to turn a Zigzagoon into a Linoone. Would also like to thank FanficPheonix, mikeyX, Brawlersinthezone and Lan for their contributions as well, couldn't have done it without you guys!
There are plenty of other features I'd love to bring to this project in the future, so anyone knowledgeable in the ways of coding who wants to work on a project like this please get in touch!

How to patch
Download either the Johto, Kanto, or Hoenn version of Grand depending on which set of starters and legendaries you want to catch and play with
Apply the patch file to a clean Pokemon ColosseumISO using any UPS patcher. This patch was made for the NTSC (US) version so it will not work on other versions. The iso is quite large so it may take a few minutes.
Always patch onto a clean ISO, even if you are applying an update.
When patching make sure file isn't a nkit file. If it is, please note that the patch will not work and you will need to convert the file into an ordinary ISO, or source another ISO.
Recommend using a fresh save for all the features to work properly
Make sure to use the nuzlocke patch after you've patched it using the main patch
