mame: update to 0.263.

Are you all ready for MAME 0.263? This release has some big changes
that are going to affect everyone: several default UI control
assignments have changed, including pause and save/load state. The
changes will hopefully make life easier for people emulating
computers. After updating, please check the User Interface input
assignments and make any changes necessary for your setup.

We’ve fixed some long-standing bugs this month. Issues affecting
large hard disk images (tens of gigabytes) have been fixed, and
chdman will now report more invalid combinations of options rather
than just producing invalid output files. Crashes or hangs when
emulating systems that use discrete sound circuitry simulation on
multi-core ARM systems should be fixed, as well as occasional bad
sound output from the discrete circuitry simulation.

Thanks to recent work reverse-engineering the K052591 chip, this
release features improved protection simulation for Hexion, S.P.Y.
and Thunder Cross. Newly supported systems include a few computers
from the former Yugoslavia, two more Tiger LCD games, and several
more chess computers. The ROMs for the unreleased Deluxe Color
Computer have been dumped recently, allowing emulation to be
completed, and there’s a big update for the Apple II software lists
this month.
