(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.
namcos21: kill some trampolines; 'user' memregions get real names (nw)
(MESS) wswan.c: converted to use slot devices for carts. [Fabio Priuli]

out of whatsnew: another case of on-cart SRAM & EEPROM pointers removed from the main system...
(MESS) wswan.c: re-added internal header logging and automatic
rotation of vertical games. nw.

(nw)
some fuuki refactoring (nw)
removed unused private member. nw.
(MESS) apple2: IIe and later don't require double-reads on the language card. [R. Belmont, Peter Ferrie]
(mess) pc9801: make ide almost work (nw)

This one will actually try to boot with the changes noted in the source (the tvram change may work for sasi too along with the sasi rom in 2hdif.rom) but there appear to be pio timing issues so when it branches in the bootloader it lands on the wrong instruction.  The ide rom has a few 386 instructions in it so it won't work with the ux.
model3: Rewrote 2D tilemap rendering. [Ville Linde]
