[PS2] Kingdom Hearts II (PAL) Multiplayer Hack

[zhanj]

Here is a proof of concept for a multiplayer hack for the PAL version of Kingdom Hearts II. Currently only individual movement works.

It works by running a custom subroutine in which it assigns different controllers for each playable character. You can watch it in action in the video below. Ignore the screwed up run animation at the start.

Multiplayer Mod (Only supports individual movement. Use in conjunction with a Party or Character modifier)

That's pretty cool. I hope they get the rest of the moves working.

Interesting, but why is there a clone of that character? Are you able to change your character in this game so you can run around as goofy or another character and the main character follows you instead? If so there is probably a boolean that controls the AI in the player pointer and it would be easy to disable one of the AI characters and give them player properties instead. With a bit more work you could also give them fighting properties as well.

It's possible to control AI characters if you put them into slot 1 of the party but they are pretty much useless as they cannot do anything besides move, jump and attack (no combos). In regards to Sora following you instead: Sora doesn't have an AI so it wouldn't work. I assume assigning another character's AI to Sora would crash the game.

Each character has a role value (player, party member, enemy etc.). However, changing anything that isn't a playable character into the player role crashes the game.

There are codes that let you play as other characters but they are quite hard to make.
