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

Overall this mod has been tremendous! It makes me feel like I'm experiencing the game for the first time all over again. It gives me such a different experience with the new selection of pokemon, the new movepools, abilities, and typings. That being said, I have one massive gripe with the mod. So many pokemon have new typings that they didn't before (which isn't necessarily a bad thing) but there were some huge oversights in type match ups. I have been hit by moves on various pokemon that shouldn't have been super effective but were and moves that should have been super effective weren't. This happened on a select few pokemon. I double checked the updated typings just to make sure I wasn't missing something and even with the updated types it should have been a different effectiveness. This can and should be changed in a future update as it disrupts my game play horribly. Since this can be fixed so easily and since this is such a good mod aside from this one issue, I still give it 4/5 stars and I plan to eagerly play through hundreds of times with each version so I can try out every new strategy possible. Thank you for allowing me to relive my childhood again.

Response from the author:

Glad to hear you're enjoying it! Out of curriosity what moves are you talking about being effective that shoudn't be? As far as I'm aware the only two moves that are currently mislabled are leaf storm and draco meteor, and that's a text issue, so is it those you're talking about?

I am a big fan of the original games for the gamecube and because this rom hack is not too transformative I would say it is hard not to like it, I do like the increase in difficulty too. I know this is an early version of this rom hack so I didn't have the biggest expectations though I do wish there were more shadow pokemon added to it. I've already beaten Venus and I dont think I have encountered a single new shadow pokemon yet which is strange. Also I am not too much of a fan of the first 7 zones of Mt Battle being turned into easy exp grinding. I was personally quite a fan of the 100 round gauntlet. Lastly I would particularly enjoy if there were more quality of life changes, if you could manage some way to purify shadow pokemon earlier that would be quite nice.

Though what is arguably a bigger problem I have with Colosseum is that actually purifying all of the shadow Pokemon is a huge pain. I assume that is part of the reason why Mt Battle is the way it is in this hack, but it feels like a relatively inelegant solution. If there was somehow a way to integrate the purification chamber from XD into Colosseum that would probably be the best way to deal with this, but I realize doing so might be quite the undertaking. It just really sucks having to either grind for hours in Mt Battle or having to spam every enemy in the game with shadow rushes until you get enough hyper modes to purify all of the Pokemon.

Response from the author:

Hey! Glad to hear you've enjoyed it so far. Yeah Colosseum hacking isn't where XD hacking is yet I'm afraid so expanding the number of Shadow pokemon is currently possible. I'm considering lowering the purification requirement in a future update as the later Pokemon are very annoying to purify, but think the rate at which the early game mons loose their gauge is pretty balanced considering you can burn through an entire shadow bar in one battle if you play it right. Sadly the purificiation chamber would probably only be possible if you rebuilt the entire game in XD's engine haha.

I've really enjoyed this mod its a welcome improvement, however I was wondering if you would be able to make it compatible with the PAL version of the game, I only ask because I play a lot of game cube games on my retroid and NTSC game cube iso don't run as well on there as PAL iso do

Definitely enjoying this playthrough, a nice change to a game I haven't played in quite a few years. I'm glad I'm doing this playthrough in a new way. One thing I just noticed, I have Espeon with Dig and Plusle with Discharge which hits all pokemon on the field. Unfortunately, discharge is still hitting Espeon while using dig, making that a non-viable strategy

I like the game overall but is there a way to only change what mons you encounter and not hack the mons themselves.  I know it's meant to be harder but when I realized that the mons I was fighting were immune to dragon I realized that the hack went to far for me.  Just cuz I couldn't predict anything.

I started playing this hack a few days ago and now that I am finished and it has been a pleasant experience.
- I know that in the original there werent that many shadow pokemon, but it may have been possible to add a few more. Its mostly the same Pokemon as in the original, except for a few like Salamance out of my head. and not only the shadow pkmn, most of the trainer have the exact same pkmn.
I even remember getting Heracross here in the Pokemon Lab and in the original in Realgam Tower. It could have been a new pkmn instead of it switching with another one.
It got a little stale for me.
I find it good however, that most of the trainer pokemon are evolutions. Take for example the first trainer in the game.

- The Master Ball Glitch still is in the game. It works by catching a shadow Pokemon with your first pokemon and than switching the master ball with another ball in your items. It could be prevented by simply turning it off. So you cant switch items while in battle. It isnt a big deal, you can just avoid to do it in the first place. 
Also a wider variety of balls to buy would be a good inclusion. And not beeing able to buy balls in other places and only in Outskirt Stand.
Same goes for some other items.  Also its nice that it seemed a little easier to catch pokemon. Was the catch rate for the 3 dogs higher? I did like that. 

- Trainers tend to be a little dumb. Sometimes they boost their stats even tho they only have 10% hp left. They sometimes attack the pokemon that is resisting their attack and not the one weak to it. The lvl Cap is fine however. You are never overleveled and thats a good thing. You also dont have to grind as much. Its a good pacing.

- Items overall. I know its 3rd gen but if we take Pokemon xg for example, there was not only Choice band, but Choice specs and lifeorb included. Some others as well. Having more options when team building is always good. 
 

I did llike many quality of life changes tho. Including physical/special split was needed in these old games. Many pokemon were unusable because of that. Reusing TMs, beeing able to see your shadow pokemons nature before it is freed. That wasnt possible before.

Having said all that, I dont know how hard it is to program new things into the game. Like more shadow pokemon or new items.
I still think it was fun overall, but it could defintly improve a little :)

10 hours into the game and my opinion is pretty much exactly the same as JackLikesBeans. I know this is only 1.1 and the work made to enhance the difficulty is great, although I'm personally not a big fan of the types and abilities change because most of my lost battles comes from completely unexpectable strategies and it's a bit obnoxious because you know at some point you're going to be caught off guard. I wish there was some kind of toggle which would let the player decide if they want to play with Drayano's modifications. I'm curious if you guys have planned to add more battle music from the battle mode in the future? Colosseum music is cool but it's always the same few ones we get to hear.

Im enjoying this version of colosseum a lot. The revamped encounters and moves has been a lot of fun, but there is an issue with the sceptile line. Idk if it's intended, but it seems odd to use the old version of lightning rod in a game that's so revamped. First time i used grovyle to tank a lightning move, i was severely disappointed to find myself getting hit instead of rewarded for good switching. Other than that, i dont think i have any issues with the game.

I am genuinely enjoying this, but the more that I play, the more I realize that this is still in beta form. Typings are not done properly. Muddy water just hit my meganium for super effective damage. 

Response from the author:

Sorry but are you sure it wasn't sludge wave you got hit by for super effective damage? As it uses the same animation..

If the 1st Pokemon Game made for GameCube is the hardest does that mean the 1 with Shadow Lugia is the 2nd hardest ? 

Are you also going to work on that disk as well ? 

Also wondering if you could hack it to instead of HAVING to return Bonsly if you could make it to where players are given a choice between unfortunately returning to the girl or getting to keep it ? 

I Really Loved Both Games As They Were But NEVER Was Able To Finish Either ,{and I know with your "update" that I Really Won't Be Able To Finish}, (😀😄😂😆🤣

Have you figured out a way to get rid of the accompanying "most of the time in the way" girl ? 

There are some things that I totally hated in the games besides never getting to finish them 

some are

the annoying girl that kept getting in the way , 

the makers of Pokemon making Hitmonchan males ,[I know they're for Jackie Chan but come on they look more female in hiked-up mini-skirts], 

and when I seen the 1 with Shadow Lugia in the NINTENDO Magazine ,{which in the day was an extremely excellent magazine}, I thought "WOW SHE ,(the 1 players would be), IS REALLY NEAT AM GOING TO LIKE PLAYING AS HER !!!" Then was shattered to find out it was a boy 😭 . And when I found out I thought " Come On In The 1st Was A Male ... That Was Ok .... I usually don't like playing as a boy but hey . HELLO MAKERS OF POKEMON WHY WOULD YOU MAKE THE 2nd 1 ALSO A MALE ? GIRLS LOVE PLAYING POKEMON AS WELL !!! 

I've watched the Animè ever since it came to the U.S.Of A. I can never get enough of it . I enjoyed their jukebox karaoke and their guessing\trivia game before and after the ads . And I REALLY LOVED THE MAIN THEME !!! 

Thank You So Much , Have A Nice Day !!!
