It looks like third-party Wireless Nunchuks operate differently than the original Nunchuk-Extension. Anyone have a clue?

+:Based on my testing with a uC, it seems that all 3rd party Nunchuks can be communicated with using this procedure:
+::Initialize:
+:::Write 0xA4, 0xF0, 0x55 (address, register, data)
+:::Write 0xA4, 0xFB, 0x00 (address, register, data)
+::Read:
+:::Write 0xA4, 0x00
+:::Read 6 bytes from 0xA4
+
+:I have tested this procedure to work well with the following Nunchuks (Compatibility/I2C speed listed after the host controller)
+::Wired
+:::Nintendo brand official
+::::Arduino: Default
+::::NXT: Default
+:::Generic
+::::Arduino: Default
+::::NXT: Default
+::Wireless
+:::memorex Sidekick
+::::Arduino: Default
+::::NXT: Fast
+:::Nyko Kama wireless
+::::Arduino: Default
+::::NXT: Default
+:::datel Blade FX
+::::Arduino: 400kbps
+::::NXT: No
+:::intec
+::::Arduino: 400kbps
+::::NXT: No
+:::One generic nunchuk I tested behaves identically to the memorex Sidekick (and the receivers seem to be interchangeable)
+::::Arduino: Default
+::::NXT: Fast
+:::Another generic nunchuk I tested behaves identically to the intec (and the receivers seem to be interchangeable)
+::::Arduino: 400kbps
+::::NXT: No
+:The Arduino I used was an Uno, and I used a WiiChuck for the physical interface. For the NXT, I used NXC with the latest enhanced firmware available at the time of writing this, and an NXTChuck as the physical interface. These are the results of my testing, but YMMV.
