mednafen: update to 1.29.0

   Notable changes since 1.28.0-UNSTABLE:
     * Added support for playing the SCSP-generated music from most Sega
       Model 2A, 2B, 2C, and 3 arcade games.
     * PCE: Fixed a memory initialization bug that could cause graphics
       glitches after the explosion of the first boss in "R-Type".
     * PCE, PCE-Fast: Fixed unreadable black letters in "Order of the
       Griffon"'s password entry screen.
     * SNES: Fixed broken emulation on little-endian PPC64 due to endianness
       misdetection.
     * SNES-Faust: Fixed S-DSP pitch modulation being half as strong as it
       should be.
     * VB: Fixed a VSU modulation emulation inaccuracy that severely
       distorted some sound effects in "Virtual Boy Wario Land".

   Notable changes since 1.27.1:
     * Stricter parsing of the configuration file and numeric setting values,
       with error messages now containing line numbers when relevant.
     * Added setting "video.force_bbclear", default value of \ 
"0", which when
       set to "1" will force clearing of the backbuffer before drawing \ 
every
       frame.
     * Added setting "video.cursorvis", default value of \ 
"hidden", to allow
       for showing the windowing system's mouse cursor within Mednafen's
       window even when it's not required.
     * Implemented an M3U recursion limit of 9, adjustable by the new setting
       "cd.m3u.recursion_limit".
     * Implemented a limit of 25 on the total number of CD images loaded
       while processing M3U files, adjustable via the new setting
       "cd.m3u.disc_limit".
     * Added Zstandard decompression support to game loading, with both naked
       files("zst" extension) and ZIP archives.
     * Added support for loading CD images from ZIP archives when the
       "cd.image_memcache" setting is set to "1". The ZIP \ 
archive may be
       loaded directly, or indirectly via an M3U file. An M3U file may also
       exist within the ZIP archive, to allow loading multiple CD images from
       within that ZIP archive. However, loading from a ZIP archive within
       another ZIP archive is not supported.
     * Changed the naming of save games, save states, etc. for
       gzip-compressed games. Previously, a gzip-compressed file named like
       "whatever.nes.gz" would generate a save game named like
       "whatever.nes.<HASH>.sav", but will now generate a save \ 
game named
       like "whatever.<HASH>.sav", the same as if \ 
"whatever.nes" had been
       loaded instead of "whatever.nes.gz". The old behavior may be \ 
restored
       by setting the new undocumented setting "filesys.old_gz_naming" to
       "1".
     * SS: The emulated reset button mapped to Mednafen's reset command
       key(F10 default) will now respect the "input.ckdelay" setting.
     * SS: The VA0/VA1 motherboard's memory mapping behavior for Low-RAM is
       now emulated instead of VA2's, to fix a crash in "Myst" in the
       generator room.
     * SS: Fixed unresponsive input in "Discworld".
     * SS: Fixed startup abort to CD player screen in the Europe and USA
       releases of "Primal Rage".
     * SS: Fixed abort to CD player screen when trying to start a game demo
       in Gremlin Interactive's "Demo Disc".
     * SS: Fixed inability to skip the intro FMV in "Senkutsu Katsuryu
       Taisen: Chaos Seed".
     * SS: Fixed flickering title screen in the "Saturn Super Vol. 2" \ 
demo of
       "Golden Axe: The Duel".
     * SS: Fixed a regression introduced in 1.26.0-UNSTABLE that broke the CD
       audio player in the North America/Europe BIOS.
     * SS: Implemented emulation of the CD block Scan command, to allow the
       scan forward/backward functionality in the BIOS's CD audio player to
       work.
     * SS: Fixed a bug in the CD seek handling code that could cause more
       emulator frame pacing and sound buffer underrun issues than strictly
       necessary when CD image memory caching is not enabled, the default.
     * SS: Corrected a few inaccuracies in the relative timing between
       different SCSP EG rates and between different SCSP timer prescaler
       rates(probably with negligible audible effects in commercial game
       sound drivers).
     * VB: Added "left" and "right" options to the \ 
"vb.3dmode" setting, to
       allow for more easily showing only the left or right view.
