About This File
Very happy to finally be able to share the first full Pokemon Colosseum QOL and difficulty ROM hack to date!

. Physical/Special split
. Fairy type
. 65 New moves
. Stat/type/Ability updates and changes (In line with Drayano's hacks)
. Revamped TM list with 8 new TMs
. Infinite TM use
. New shadow encounters
. Gym themed Colosseum battles
. Higher difficulty
. Alolan Ninetales and Marowak
, Different versions based on which set of starters/legendario trio you want

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 protagonist333 for their texture work on Rui and the Alolan forms, as well as FanficPheonix 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
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.
Any previous Colosseum save files will be compatible with future patches, however any version differences involving Shadow Pokemon may result in missing out on certain features.
