Time for a new release. There are a few important emulation improvements and
a few new features; but for the most part, this release focuses on major code
refactoring, the details of which I will mostly spare you.
The major change is that, as of v099, the SNES balanced and performance cores
have been removed from higan. Basically, in addition to my five other
emulation cores, these were too much of a burden to maintain. And they've
come along as far as I was able to develop them. If you need to use these
cores, please use these two from the v098 release.
I'm very well aware that ~80% of the people using higan for SNES emulation
were using the two removed profiles. But they simply had to go. Hopefully in
the future, we can compensate for their loss by increasing the performance of
the accuracy core.
Changelog:
SFC: balanced profile removed
SFC: performance profile removed
SFC: expansion port devices can now be changed during gameplay (atlhough you
shouldn't)
SFC: fixed bug in SharpRTC leap year calculations
SFC: emulated new research findings for the S-DD1 coprocessor
SFC: fixed CPU emulation-mode wrapping bug with pei, [dp], [dp]+y
instructions [AWJ]
SFC: fixed Super Game Boy bug that caused the bottom tile-row to flicker in
games
GB: added MBC1M (multi-cart) mapper; icarus can't detect these so manual
manifests are needed for now
GB: corrected return value when HuC3 unmapped RAM is read; fixes Robopon
[endrift]
GB: improved STAT IRQ emulation; fixes Altered Space, etc [endrift, gekkio]
GB: partial emulation of DMG STAT write IRQ bug; fixes Legend of Zerd, Road
Rash, etc
nall: execute() fix, for some Linux platforms that had trouble detecting
icarus
nall: new BitField class; which allows for simplifying flag/register
emulation in various cores
ruby: added Windows WASAPI audio driver (experimental)
ruby: remove attempts to call glSwapIntervalEXT (fixes crashing on some Linux
systems)
ui: timing settings panel removed
video: restored saturation, gamma, luminance settings
video: added new post-emulation sprite system; light gun cursors are now
higher-resolution
audio: new resampler (6th-order Butterworth biquad IIR); quite a bit faster
than the old one
audio: added optional basic reverb filter (for fun)
higan: refresh video outside cooperative threads (workaround for shoddy code
in AMD graphics drivers)
higan: individual emulation cores no longer have unique names
higan: really substantial code refactoring; 43% reduction in binary size
