First and foremost, thank you for making this possible.
Unfortunately, it doesn't seem to work on Monterey 12.1 (21C52).

I've just got a question, rating in no way indicate how I feel about the tool. Why is is on modern mac (Monterey) releases saying the file should be moved to the trash and not letting me open it? Any help would be appreciated

These games really need more love, and this man is single handedly making that possible (more or less), and on top of that, these tools are pretty easy to use compared to even the GBA / DS tools out there, which is incredible considering how much larger those scenes are. Phenomenal work dude, keep it up.

Is there an issue with the randomizer? I set it to randomize species, moves, abilities, and TM moves, and it's still trying to randomize after 2 hours. I reset it once before after 30 minutes.

Sounds good but I don't own a Mac, so would one of you kind people be able to create a basic randomizer for me to use on Windows please, I would be grateful. I just want Random Trainers, Random Shadow Pokemon, Random Wild Pokemon, Random Field Items (Not Random Moves, Abilities or Types) Thank You ❤️ :D

Probably one of the best tools out there for pokemon. The user interface is simple and easy to use. The tool extracts and recompiled your source code for you, making life much easier. You can edit many things in this, including trainers and their pokemon, pokemon stats, moves, type charts, etc. You could even add more pokemon to trainers, up to a total of six! With this tool, it seems the sky's the limit. This tool has been a works in the making, having to be updated constantly to make things work. It still sees a few glitches now and then, but you won't have to worry about hassle with updates; the creator has listened to our issues with the program and has responded very kindly and has made necessary fixes to the issue.


A note on operation system compatibility. This program seems to be made from scratch, and thus, if a Windows version or Linux Version was to be made, it would also have to be made from scratch. I believe the creator could do it given enough time, motivation, and reason to, to create ports. But as of right now, if you want to operate this on Windows or Linux, you would either have to set up a Mac with OSX, or use a hackintosh (virtual box+Sierra/High Sierra+Tool). I use a hackintosh on Windows 10 Pro to use this software, and it works as expected.

Can someone help me randomize the game? I don't know how to use the XD tool with windows?

So after a couple days of toiling with things I am finally playing my first run of randomized Colosseum. Something of note is that version 1.0.1 of the Colosseum tool crashes when you try to extract or rebuild the ISO. So what I did was used the 0.9.0 version for extraction and rebuilding and edited with the newest version. The XD tool works just fine.

As for the randomizer itself (For both tools) I don't know if it is bugged, if my virtual machine has some incompatibilities with the program, or if it is just a super long process but randomizing anything other than the Pokemon Species causes the tool to just sit there and hang, and I have waited for 2 hours to see if it would complete and nothing would happen. However having all of the Pokemon randomized is good enough for me so I'm not losing any enjoyment out of it.

One last thing is I love the ability to go in and alter things after the randomization to make sure my experience goes smoothly. I mainly used it to alter my starters move pool and upped the catch rate on the tougher to catch Shadow Pokemon. So overall, it is currently a mixed bag. I look forward to future updates and seeing how the tool improves.

(for version 1.0.1)

Half of this program is really good.

The XD tool works very well, is very well designed, and I have thus far experienced no problems. It edits (or randomizes) every part of the game. The best tool you could want. 

However the colosseum tool, which is what I wanted to use, doesn't work at all. It appears as if the colosseum program is an edited version of the XD program (for example, the program name in the top bar is 'XD tool'). The interface looks fine but upon attempting to load a Colosseum.iso, the program will always crash. Hey, StarsMmd, I've seen that you update these programs very often. Could you fix up the Colosseum tool so that it actually works? 

Also, to all those asking for the program to be ported to windows: this program appears to be built from the ground up, for mac. A Windows version would likely need to be built from scratch, and be a large undertaking for StarsMmd (if they could do it at all). If you cant access a Mac, I'd look for StarsMmd's tutorials, which don't require the use of his tools, rather than badgering him for a windows version.

One of the best things on the internet to me. Pokémon Colosseum and XD are my favorite games ever, and being able to hack them is something truly special to me. It's also the only Pokémon hacking tool that really worked to me (every time I hacked a portable Pokemon game, I've had errors). This tools had to be updated a few times to work properly, but the creator is very friendly and capable of fixing all the problems.
