upd765: implement scan data and read track [Carl]
        fail command when drive not ready and check ready before command (verified on real hardware)
        stop polling when first byte of command sent (verified)

(mess) x68k: experiment with fdc drive control (nw)
nonsense
small cleanup
(MESS) gb.c: Added GameBoy Pocket Boot ROM. [BennVenn]
rm really old todo list
rm gblight clone, implementation was identical to gbpocket
SDL: fix 0.153 regression where user GLSL shaders didn't work. [R. Belmont]
SDL: Fix shaders for games that output indexed16 (e.g. pacman). [R. Belmont]
namcos1.c: Completely rewrote the emulation of the CUS117 MMU.
The MMU is no longer emulated by modifying address maps at
runtime, an operation which has become excessively slow as the
core memory system has accumulated features and complexity over
the years. Instead, the MMU is now a device which works on
similar principles to the address_map_bank_device. The recent
multisession regression is fixed, all games in the driver
should now run substantially faster, and most importantly the
driver code is now much cleaner and easier to understand. [Alex Jackson]
upd7810: reorganize, compile source files seperately instead of
including them into the main source
vtech1: Add "VZ-200 Enhanced BASIC V1.01" [Chicken Man]
(MESS) lx800: Refactored Epson LX-800 from a driver into a Centronics device. (nw)
(MESS) ex800: Refactored Epson EX-800 from a driver into a Centronics device. (nw)
move tmpz84c011 specifics to its own files, make z80ctc a subdevice rather than adding it separately it in each driver using a tmpz84c011. (nw)
upd765: drop the polling irq when anything is written to the controller in command mode (verified on actual hardware) (nw)
Fixed build. (nw)
hd63540: oops (nw)
hd63450: this time it's really right (maybe) (nw)
new clones
Space Invaders (Electromar, Spanish) [Roselson, Ricky2001 from Aumap]
(MESS) Added Yamaha FB-01
I haven't been able to test if this makes the expected sounds when a midi keyboard is hooked up the midi-in port of this device.
