I added I2C decoder, game does this repeatedly:

Write 0x40 to register 0. (Perhaps this means "latch current time")
Read registers 1 and 2
Write 0x00 to register 0. (Reset latch)

EDIT: This would make sense with PCF8593. Bit 6 is "hold last count flag" and 1 and 2 are hundreds of seconds and seconds.
