higan v102 - 模擬器

https://byuu.org/

This release adds very preliminary emulation of the Sega Master System (Mark
III), Sega Game Gear, Sega Mega Drive (Genesis), and NEC PC Engine
(Turbografx-16). These cores do not yet offer sound emulation, save states or
cheat codes.

I'm always very hesitant to release a new emulation core in its alpha stages,
as in the past this has resulted in lasting bad impressions of cores that
have since improved greatly. For instance, the Game Boy Advance emulation
offered today is easily the second most accurate around, yet it is still
widely judged by its much older alpha implementation.

However, it's always been tradition with higan to not hold onto code in
secret. Rather than delay future releases for another year or two, I'll put
my faith in you all to understand that the emulation of these systems will
improve over time.

I hope that by releasing things as they are now, I might be able to receive
some much needed assistance in improving these cores, as the documentation
for these new systems is very much less than ideal.

Also, please note that starting with this release, I am omitting the
settings.bml file. This means that you will have to manually configure your
gamepad input assignments, and select the appropriate devices from the system
menu after loading games. You may also want to select a more conservative
driver profile than the default (OpenGL, WASAPI.) If they cause you any
troubles, a safer bet would be (Direct3D, DirectSound.)

The good news in omitting this file is that you'll only have to configure
inputs once, and you won't lose any customizations by upgrading to future
releases.
