Question about Joker Commands for PS2 Games

[BigBossman]

Hi,

I know that some games have more than one joker code, but how does it work for games that have multiple games on it. Mainly Namco Museum 50th Anniversary, Midway Arcade Treasures 1, 2, & 3, Taito Legends 1 & 2, & Capcom Classics Collection 1 & 2.

Will one joker code work with all the games on a particular disc? Or do you have to have a different joker code for each game? For Example: If I took a joker code for Mortal Kombat 2 on Midway Arcade Treasures 2 & used it for A.P.B. would it work? Or would A.P.B. require a completely different joker code?

It depends. As a general rule, the pad setup is done once at startup, and running a particular game within the emulation framework doesn't redo that. I think you can pretty much count on that for any collection that's just a bunch of emulated games from older systems. If it's actually a multi-ELF game of some kind, you'll likely find that the pad buffers move around.

Edit: That being said, with emulation there could be cases where you need to manipulate how the pad is handled within the emulated game, in which case you'd need to know how it interacted with the original hardware. That could still vary from game to game, regardless of whether or not the outer, PS2 pad buffers are static.

those collections, each game / emulator have their own elf
you will need find joker for each game / emulator

also check Skiller's collection codes 7z files if joker already made

Yeah, that's another thing I neglected to mention. If you have a collection spanning 30+ years of arcade games or something, it's likely they involve emulators for several different boards. With the PS2's limited real estate, different emulation modes probably mean different executables/ELFs.
