Emulator

What's the problem?
DKCR is not playable anymore.

Dolphin version with the problem as it appears in the title bar: Don't remember exactly: since early 74xx or late 73xx builds.

32-bit or 64-bit: 64-bit Win7

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"): SF8P01

Was the ISO a plain dump from disc, compressed and/or scrubbed? Plain dump.

Please provide any additional information below.
Wiimote (genuine) disconnects all the time (this is the only game I have which has this new issue, so far). Have to press Alt+F5 twice to be able to play 30 more seconds.
I have a lag of 0.5 second too, which makes the game unplayable. This lag is present only if playing with a real wiimote: it works perfectly with the emulated one. You can see the difference even if you switch on the fly (means without restarting the game).
