208 GetBatteryTemperature usually will get back temperature of battery compartment/batteries. GetBatteryTemperature is implemented in Canon's firmware for SX120IS.
209 Firmware entry point is identified (0xFFC394D8) but function is not usable. Camera will crash if Canon's GetBatteryTemperature is called by CHDK.
210 To avoid a crash Canon's GetBatteryTemperature must not called. As long CHDK general code do not distinguish between cameras that support or don't support GetBatteryTemperature,
211 this function will be implemented as specific CHDK-code. It returns always with -99 (which means -99° Celsius or -146° Fahrenheit).
212 Original entry point in Canon's firmware is disabled (in stubs_entry.S).
