Wii Off-brand Nunchuck Internals

Nyko "Kämä" Wired Remote:
MCU: Atmel ATMega 48 TQFP (The PCB also has pads for MLF package, based on availability?)
Accelerometer: Freescale A7260
EEPROM: Macronix (MXIC) MX25L4005 (4 Mbit)

Definitely a good nunchuck for hacking; it's well-built, and the analog stick appears to be mostly metal-based, instead of plastic like others.

I wonder if the ATMega is read-locked? If so, I wonder how hard it would be to rewrite/repurpose it...

Biogenik OG1-CHUK:
The only thing of interest was a single epoxy blob on the PCB.

Madcatz Z-CHUK Wireless: (FCCID: P25S1MC5746U1709C, 2.405-2.475Ghz)
MCU: Epoxy blob of unknown origin
Accelerometer: Unknown. "033 A841 013"?
EEPROM: STMicroelectronics M24C02 (2 Kbit)

Wireless is nice, and might make for some interesting projects, and at $10/piece from XSCargo, it's definitely an affordable way to get into wireless (and accelerometers, etc). The internals of this remote look almost identical to the actual Wii Nunchuck, with the exception of the battery and transmitter.
