emulators/jgenesis: update to 0.8.3
New Features
(Genesis / Sega CD / 32X) Added an audio setting to select 1 of 4 different \
audio low-pass filters, with cutoff frequencies ranging from about 15000 Hz \
(comparable to the existing filter) to about 5000 Hz (produces a very soft \
sound)
(Genesis / Sega CD / 32X) Added a video setting to enable/disable individual \
graphics layers
(Sega CD) Added an audio enhancement setting to apply linear interpolation \
or cubic Hermite interpolation to PCM sound chip channels; this significantly \
reduces audio noise and audio aliasing in games that play music or voice acting \
through the PCM chip (e.g. Lunar: Eternal Blue all the time, Sonic CD in past \
stages, basically every FMV game for cutscene audio)
(GB) Added an option to use a custom 4-color palette, with a color picker UI \
for configuring the custom palette colors
Added a new hotkey that completely exits the application (#140)
The previous "quit" hotkey (which only closed the currently \
running game) has been renamed to "power off"
Improvements
(32X) PWM chip audio output resampling now uses cubic interpolation rather \
than a filter that assumed a source frequency of 22 KHz; this should improve \
audio quality in games that use PWM sample rates other than 22 KHz (e.g. After \
Burner Complete and Space Harrier)
Input mappings that use modifier keys (Shift / Ctrl / Alt) no longer \
distinguish between Left and Right versions of the modifier, e.g. Left Shift and \
Right Shift are now both treated as simply "Shift" for input mapping \
purposes (#139)
Redesigned most of the audio low-pass filters to explicitly target a cutoff \
frequency of about 15000 Hz with a stopband edge frequency of about 20000 Hz, \
which should further reduce resampling-related audio aliasing
For performance reasons, NES and GB/GBC instead target a cutoff \
frequency of roughly 10000 Hz with a less steep attenuation slope past the \
cutoff frequency
Implemented a performance optimization in how audio low-pass filters are \
applied when running on CPUs that support x86_64 AVX and FMA instructions (which \
is almost every x86_64 CPU made in the last 10 years; AVX2 is not needed)
(SMS / Game Gear / Genesis) Improved video memory viewer UI so that it's now \
possible to view CRAM and VRAM simultaneously, as well as current VDP settings \
(captured once per frame at the beginning of VBlank)
Display scale factor / DPI is now taken into account when determining \
initial emulator window size in windowed mode
GUI: The GUI window is now repainted immediately when a directory scan \
finishes, rather than requiring mouse movement or a keyboard input to trigger \
the repaint
Fixes
(32X) Fixed the 68000 incorrectly being allowed to change the PWM timer \
interrupt interval via $A15130 writes; this fixes Primal Rage having horribly \
broken sound effects
Fixed an input configuration bug that made it effectively impossible to \
correctly configure any gamepad where SDL reads digital buttons as analog axes, \
such as the 8BitDo M30 with its C and R buttons (#135)
Fixed some minor bugs in the common audio resampling code related to how \
low-pass filters are applied
CLI: For options that only accept a fixed set of possible values, the list \
of possible values in the help text is now auto-generated at compile time; this \
fixes at least one case where an option's help text listed a possible value that \
does not exist, and another case where an option's help text omitted a valid \
possible value
