mame: update to 0.255.

As you may have expected, it窶冱 MAME 0.255 release day! Following
on from April窶冱 breakthroughs, Namco System 10 MP3 audio is now
supported, making Golgo 13: Juusei no Requiem, Seishun Quiz Colorful
High School and Nice Tsukkomi fully playable. On top of that, Point
Blank 3 and Gunbalina now run, and the later version of Gamshara
has been dumped correctly. If you like rhythm games, more than half
a dozen Pop'n Music titles are now working. Lots of LCD and LED
games were added this month, including two Teenage Mutant Ninja
Turtles games from Konami, Super Goal Keeper from Tronica, and two
sports-themed games from Tomy.

Remember the Motorola 88000 CPU architecture? It窶冱 OK if you don窶冲,
it never achieved the same market penetration as its rivals MIPS,
SPARC and POWER. But that makes it really cool that two Omron
workstations based on 88100 CPUs, the Luna 88K and Luna 88Kﾂｲ, are
now working. This release also adds support for the Psion HC 100
series of hand-held computers from the early 1990s. These devices
found their niche as portable data collection terminals. Support
for the ZX Spectrum窶冱 many descendants continues to grow, with the
Sprinter Sp2000 arriving this month.

Of course, there are lots of other changes, including software list
additions, bug fixes and general emulation improvements.
