mame: update to 0.248.

It must be that time of month again – time for MAME 0.248! The
Hartung Game Master was one of several hand-held game consoles
positioned as low-cost alternatives to the Nintendo Game Boy. It
was notable for its somewhat unconventional choice of an NEC µPD78C11
CPU, its low screen resolution, and the poor quality of its software
library. And now, for the first time, you can relive the disappointment
of all eighteen games released for the system in emulation!

Speaking of hand-held consoles, MAME now supports more Game Boy
cartridges, including the Pocket Camera, the EEPROM and two-axis
accelerometer used by Kirby Tilt ’n’ Tumble and Command Master,
and several memory controllers used for unlicensed games and
compilations.

Still on the topic of Nintendo, MAME now emulates the earliest
version of the RP2A03 audio processing unit, used on arcade boards
as well as early production runs of the Famicom console. Several
games play sounds incorrectly with the later RP2A03G used in the
NES and the majority of Famicom consoles. Several issues with
Famicom peripherals have been fixed, too.

MAME’s Win32 debugger can now save your window arrangement, and
there’s an option to use light text on a dark background. On recent
versions of macOS, MAME’s Cocoa debugger now follows the system
colour scheme.
