Haha yeah the mod is really only functional for the PAL version at this point in time. I should move it to FInal Mix but currently too busy to work on this mod. I've updated the original post with instructions for anyone else wondering.
No way to make it splitscreen as of writing. It'd be very hard to implement
You'll need to use an emulator to enable the cheat code from the main post. You'll then need to use a party modifier code to have two Soras in your party. Once that's done, start a new game or load a save file. You'll have two Soras that are controlled by independent inputs.
From a quick look, it doesn't seem like KH2 supports multitap so it's probably not possible without some massive code rewrites. Separate health bars would be possible but I don't have the time to implement it at the moment. If you want to learn how I made the hack, I've updated the original post with a link to how I did it.
Here is a multiplayer hack for the PAL version of Kingdom Hearts II. Players can move, jump and attack independently. I have also created a semi functioning version for Final Mix (only individual movement works well). Camera controls are currently locked to Controller 1 so could be confusing moving the camera around. I do plan to fix this at some point. The code needs to be used in conjunction with a Party or Character modifier to have 2 playable characters in your party. 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. INSTRUCTIONS 1. Grab PCSX2 and have a PAL version of Kingdom Hearts II 2. Create a file called C398F477.pnach inside the Cheats folder in the PCSX2 directory 3. Use a code converter such as PCSX2CE to convert the raw codes (bottom of this post) into pnach format. 4. Use a code converter again to convert the following party modifier into pnach Spoiler 4034119C 00130001 NNDDWWMM 00000000 NN = Slot 4 DD = Slot 3 WW = Slot 2 MM = Slot 1 (Main slot Sora/Micky) 00= Roxas/Sora 01= Donald 02= Goofy 03= World Character 04= Valor Sora/ Double Keybladed Roxas 05= Wisdom Sora 06= Master Sora 07= Final Sora 08= Anti Sora 09= Mickey 10= Empty Slot 11= Something wierd, it's different in every world 5. Start emulating and make sure cheats are enabled. You should now have two playable Soras/Roxas' when you start a new game or load a save file. In the end, your pnach file should look like this: Spoiler // Party modifier to have two Soras patch=1,EE,4034119C,extended,00130001 patch=1,EE,101000,extended,00000000 // Multiplayer patch=1,EE,201BB8BC,extended,0803F400 patch=1,EE,200FD000,extended,3C0E000F patch=1,EE,200FD004,extended,35CECFF0 patch=1,EE,200FD008,extended,8DCF0000 patch=1,EE,200FD00C,extended,15E0000A patch=1,EE,200FD010,extended,00000000 patch=1,EE,200FD014,extended,25EF0001 patch=1,EE,200FD018,extended,ADCF0000 patch=1,EE,200FD01C,extended,3C0E01C8 patch=1,EE,200FD020,extended,35CE92A0 patch=1,EE,200FD024,extended,3C0F0035 patch=1,EE,200FD028,extended,35EFBCC0 patch=1,EE,200FD02C,extended,ADCF0000 patch=1,EE,200FD030,extended,0806EE31 patch=1,EE,200FD034,extended,260E09C0 patch=1,EE,200FD038,extended,00007821 patch=1,EE,200FD03C,extended,ADCF0000 patch=1,EE,200FD040,extended,3C0E01C8 patch=1,EE,200FD044,extended,35CE92A0 patch=1,EE,200FD048,extended,3C0F0035 patch=1,EE,200FD04C,extended,35EFBD20 patch=1,EE,200FD050,extended,ADCF0000 patch=1,EE,200FD054,extended,0806EE31 patch=1,EE,200FD058,extended,260E09C0 RAW CODES PAL Spoiler 201BB8BC 0803F400 200FD000 3C0E000F 200FD004 35CECFF0 200FD008 8DCF0000 200FD00C 15E0000A 200FD010 00000000 200FD014 25EF0001 200FD018 ADCF0000 200FD01C 3C0E01C8 200FD020 35CE92A0 200FD024 3C0F0035 200FD028 35EFBCC0 200FD02C ADCF0000 200FD030 0806EE31 200FD034 260E09C0 200FD038 00007821 200FD03C ADCF0000 200FD040 3C0E01C8 200FD044 35CE92A0 200FD048 3C0F0035 200FD04C 35EFBD20 200FD050 ADCF0000 200FD054 0806EE31 200FD058 260E09C0 Final Mix Spoiler 201BD774 0803F400 200FD000 3C0E000F 200FD004 35CECFF0 200FD008 8DCF0000 200FD00C 15E0000A 200FD010 00000000 200FD014 25EF0001 200FD018 ADCF0000 200FD01C 3C0E01C8 200FD020 35CE92A0 200FD024 3C0F0034 200FD028 35EFD6C0 200FD02C ADCF0000 200FD030 0806F5DF 200FD034 260E0A30 200FD038 00007821 200FD03C ADCF0000 200FD040 3C0E01C8 200FD044 35CE92A0 200FD048 3C0F0034 200FD04C 35EFD720 200FD050 ADCF0000 200FD054 0806F5DF 200FD058 260E0A30
