Updated the OP with what people have given me.
Anyone else wanna tell me what they have it working with?
DSTWO EOS 1.11
Firmware 1.18
Clean ROM
Works but occasionally freezes. No EXP glitches. The biggest problem I've noticed is if you check your party from the pause menu, then try to back out, it will freeze on a black screen.
ONLY WORKS ON PATCH MODE!
Yeah, so where's the patch for it?
"Patch Mode" is a feature in the options menu of the DSTWO. There's also "Clean Mode". Patch Mode allows you to use features, such as real-time save, cheats, and slow-motion by pressing the hotkey. It has nothing to do with whether a ROM was patched or not.
B2/W2 do NOT work on "Clean Mode" on the DSTWO.
B2/W2 PARTIALLY work on "Patch Mode" on the DSTWO.
AP stands for anti-piracy.
As far as I know, the AP patches for Black 2 and White 2 will cause the games to freeze when loading on the DSTWO.
All we can do is wait for an upgrade to the EOS that will fix the remaining AP problems encountered, such as screens freezing after viewing your party.
