(MESS) gameboy, gbcolor: added a configuration setting
(off by default) to skip BIOS checks at boot. This allows the
recently dumped Rockman World Prototype to be played,
and the Rocket Games pirate GBC carts too. [Fabio Priuli]

(MESS) gba: added a configuration setting (off by default)
to skip some BIOS checks at boot. This allows Tyrian 2000
Prototype to be played. [Fabio Priuli]


out of whatsnew: for the Rocket Games pirates it is currently unclear how real carts were bypassing
the BIOS checks on a real unit, and it would be nice to emulate it properly. however, this trick allows
to go on fixing the rest of mapper emulation until it's fully understood.
