Wiimotes are now slighty more responsive and multiple wiimotes should harmonize now slighty better. This clean up was requested/inevitable and should have be done way more earlier. This "might" break osx/linux builds, so please test. If your aware of any "real wiimote" issues please post it in the comments as well(dont forget to state your OS). Known wiimote issues: 1.) Possible wiimote disconnect on pressing the home button 2.) 1-2 Possible wiimote disconnects directly after starting a game 3.) Rumble causes lag. I don't think this is a wiimote plugin issue itself, I'm not sure tho. It would be interesting to know whether the lag still happens on emulated wiimotes as well, when the game tries to rumble. 4.) Connecting(pairing up and refreshing) a 2nd/3rd/4th real wiimote while having a game running/paused, might swap player slots and cause disconnects at that moment. If u have more issues, feel free to post them, to have them all here collected once more to get a brief overview. Apart from that, increase the wiimote read timeout @settings(20-200). If your expecting frequent disconnects, restart dolphin, and don't open the wiimote gui before playing instead directly start games. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5788 8ced0084-cf51-0410-be5f-012b33b47a6e
