problem with wiimote motion plus

[ashash56112]

hi
i just bought a new wiimote which is built-in motion plus
i did what is mention here

http://www.dolphin-emu.org/connect-wiimote.html

but when i open dolphin it took me long time to pair it
and i can only play one game with it which is "" wii play""
but the remote is not recognized by all other games

is this problem because of the ""built-in motion plus"" or something else
please help so i can fix the problem or send it back to the seller
