neogeo.cpp: Added newer Universe BIOS versions to irrmaze - this allows
the Japanese version to be seen by switching the region, and joystick
play using a cheat (although 2.3 and later also support trackball play,
a joystick is still required for setup and to use the in-game menu).
Also changed roboarma to roboarmya, as this matches the software list,
and we prefer to make clone set names using suffixes.
neogeo.xml: Added irrmaze with usage note explaining that newer
Universe BIOS versions support joystick play as a cheat (must be enabled
each session - Universe BIOS does not save cheat state to NVRAM).
lwriter.cpp: Got rid of a couple of literal tags, make use of Allman
style a bit more consistent, and got rid of a redundant part of a
bitwise or expression.
runaway.cpp: Merged video code into main driver file, split state
classes, reduced a bit of redundancy, eliminated runtime input tag
lookups, and generally tidied up code.
dai3wksi.cpp: Noted manufacture in description for runaways.
