Mednafen 1.23.0-UNSTABLESeptember 3, 2019 - 19:15 PDT
Some of the Saturn game compatibility improvements are from per-game ugly hacks. Many are from per-game cache emulation mode changes. All internal Saturn game databases, and their effects, are now documented.

A future update may implement more correct fixes via global accuracy improvements, depending on how desktop CPU performance develops.

Notable changes since 1.22.2:

Expanded and harmonized the accepted value ranges for settings "sfspeed" and "ffspeed" to 0.25 through 15, for greater versatility.
Apple2: Added support for an RGB-style video mode, selectable with the new setting "apple2.video.mode".
Apple2: Added support for custom 16-color palettes(using one will automatically enable RGB mode).
NGP: Fixed broken voice playback in "Densetsu no Ogre Battle Gaiden".
NGP: Fixed eventual save-related hang in "The Last Blade".
PCE: Fixed compatibility issues with some Super CD-ROMA2 games when using a US system card image.
SNES-Faust: Made various changes to try to improve game compatibility.
SNES-Faust: Added CX4, SA-1, and SuperFX emulation.
SNES-Faust: Added setting "snes_faust.h_filter" to control handling(e.g. blending) of lores and hires video modes.
SS: Fixed hang at end of disc 1 of "Grandia", with horrible per-game hack.
SS: Fixed hang in "Fighters Megamix" that occurred after the intro FMV played(or was interrupted), with horrible per-game hack.
SS: Fixed flickering text in "Arcade's Greatest Hits".
SS: Fixed major graphical glitches during gameplay in "Whizz".
SS: Fixed much of the graphical glitching in "All-Star Baseball 97".
