Quick summary

On PS Move enabled games, when using the "Fake" Move Handler to have a controller in Port 7-through-4 behave as Motion Controller 1-through-4, the base controller that's used is still receiving input from the base controller.

Details

Because the controller port (7 in this case) is receiving two different types of emulated input, games with multiplayer support will misinterpret it as two separate controllers - two players - on the same port. This leads to quite a few unintended consequences, such as inadvertently activating multiplayer in a session with only one controller just by pressing Start.

Tested with multiple emulated controller types on Port 7, from the basic Pad to Drums to Guitar to Dance Pad--even the PS Move Navigation type (pictured) will still show as a Wireless Controller in the same port, when that should be disabled by the parasite Move Controller.

It's been a while since I've used my PS3 (since I have a Move/Camera, as well as the game demonstrated) but from what I recall, normal Pad-type controllers should never be able to "share" a port with Motion or other types of controllers?

Other details

EDIT: For what it's worth, when going to either of the Player slots and pressing a button to set what controller corresponds to which player, it will always map the in-game slot to the Motion Controller on Port 7 and not the Wireless Controller; but pressing start while in the gameplay proper, even when overwriting this, will cause the Wireless Controller to join in as the unassigned player slot.
