TODO:
- currently implemented very basic set of Q2SD GPU features, required/used by dumped games, should be improved if more games will be found.

- hook IRQs from GPU and SPU (not used by dumped games), possible controlled by one write registers in 140010xx area.
Notes:
- hold Test + Service while booting to initialise RTC NVRAM
