also: remove nvidia-cg-toolkit as input for retroarch.
see #15707
darwin is also building but you have to trick it into
thinking it's a desktop app for the GUI to load
platforms is set to "platforms.all".
- Added missing freedesktop items (`*.desktop` and icon).
Note that for the moment, only added an `*.svg`
icon as was the only available. It does not give
us the best results (at least in xfce). We may decide
later on to extract the content of the `*.ico` instead
which is a bit more involved.
retroarchBare was too old for any practical use at this point, so it was removed in favor
of fetching releases from git. RetroArch often recommends checkout out the latest git master
if you are on a desktop platform, so we are conforming with their recommendation. I plan on
bumping the git of retroarch and each core every month, and I plan on adding more libretro
cores in the future.
The libretro cores that were added are nestopia, quicknes, snes9x, and vba-m
planned next are : bsnes-accuracy, bsnes-balanced, bsnes-performance, a few libretro mame ports
