peyper.c : improved display; added i8279 chip, added inputs.
and a few more. nw.
(MESS) msx.c: Whoops
zt blending (nw)
(MESS) New System Drivers Supported:
Peripheral Technology PT68K2 [Al Kossow, R. Belmont]

Systems Promoted from GAME_NOT_WORKING:
Peripheral Technology PT68K4 [Al Kossow, R. Belmont]
r2dx other dipswitch is flipscreen according to pcb readme, doesn't work tho
(MESS) ht68k: add starter softlist (nw)
zerotm2k inputs
woop
(MESS) concept: fix keyboard status to not return junk data, fixes bootup without -debug. [R. Belmont]
(MESS) concept: hooked up actual 6551 for keyboard, added beeper, cleaned up driver. [R. Belmont]
trident: added 2D acceleration support for 15/16/32bpp video modes (untested since XFree86 3.3 requires linear addressing, which in turn requires VLB or PCI support :()
added 32bit rom accesses to generic slot and converted pockstat and
casloopy to use the slot code. nw.
converted coleco carts to use Curt's slot device (+ changed the 
tag to avoid clash between the media switch and the slot device). nw.
mmm... not-power-of-2 ROMs (e.g. secalpha) do not like
the (size-1) masking. nw.
(MESS) dmv: added K233 and K234 expansion modules. (nw)
whops. this assert was meant to match the one at line 216. nw.
old Apple GCC at least is good at catching comparisons which are always true :)

8250: call interrupt callback after clearing internal interrupt state when resetting [smf]
8250 write protect 0x40 in line status register, this bit is used to track whether diserial is running and will call us back. mpz80 writes 0 to this bit and waits for it to be set again, it used to work because loopback was HLE'd. The 8250 datasheet says that transmission in loopback goes through the shift registers, the way the old code worked wouldn't test any send/receive functionality of the chip at all. It's unknown whether clearing this bit would cause the chip to start shifting, the datasheet says you shouldn't write to the register at all & it's reserved for testing the chip in the factory.
