About This File
Very happy to finally be able to share the first full Pokemon Colosseum QOL and difficulty ROM hack to date!
Grand Colosseum not only acts as a difficulty hack to one of the hardest pokemon games out there, but brings a host of QOL changes, including but not limited to
. Physical/Special split
. Fairy type
. 50+ 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
Head on over the the gamecube pokemon hacking discord here https://discord.gg/kPpxYVZP to shout at me about anything I might have missed.
For anyone who wants to support me you can check out my Patreon here, but no worries if not, I just hope you enjoy! https://www.patreon.com/kya_colosseum
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. 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/texture editing 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.
