These two variables are added later but not saved, however, since they
are used in the update_state method to control how many cycles to feed
to the channel update methods, they should be saved to ensure correct
emulation.

mostly needs the nametable mirroring registers emulated, and proper palettes for this extended mode
I recently noticed that it takes very long to load a gba state, sometimes
dozens of seconds, and the older the state is, the longer it takes to load.
I found out it's caused by gameboy_sound_device does not save the m_last_updated
variable, and after loading a state, in the update_state method, now could end
up being much larger than m_last_updated, and leads to substantial yet wasted
calculation of the channel state.
Simply adding save_item(NAME(m_last_updated)) should fix the problem, however,
since it will break current existing saved states, and optimize the channel
update methods is in the TODO list, I took the latter choice, now the calculation
to update the channel state is really negligible and the state loading is
almost instantaneous.

* use Caps0ff dump for srdarwin
handcraft MCU rom for srdarwinj like was done for other games in the driver so the old sim can be killed off, marked as BAD_DUMP
seems stable, although I had to boost the interleave.
NOTE, this game has never been emulated correctly

* create c-chip device with correct CPU type in it and a bunch of notes (pinout etc.)
create a uPD78C11 derived CPU type for this purpose, with internal ROM map
use internal ROM map for other uPD78C10 chips as it's always present.
add missing NO_DUMP definitions to various games using C-Chips with correct size etc.
pump megablast through the device code as really all it ever does is bank the c-chip window and test the RAM.
