XBox360 joypad analog stick setting on Dolphin 4.0-8542

The more I use Dolphin the more I impressed by it.

I tried some GameCube games that are from USA, Japan and Europe, and I found that Dolphin was smart enough to create separate virtual memory card for each of these locale.

But in order to play GameCube and Virtual Console (like Nintendo 64 and Super Nintendo),  I need to set the WiiMote setting to Hybrid Wiimote  (I bet this is the setting for Virtual Console, as it simply take whatever was set at GameCube Controller setting).  So far so good ... except that in Pokemon XD, I found my character started sliding for no good reason.

It seemed like the Radius and Dead Zone setting for Control Stick and C Stick were not set properly.  After reading some post like this one and this one, I ended up set the Radius as 90 and Dead Zone as 30 for both of them.  So far it works pretty OK.  Also, I need to forfeit the save state that I created before, as they seemed to still using the old XBox360 joypad setting.  Once I started from loading save game from memory card, everything seemed to work fine.
