This is the system "flog" 01008BB00013C000 title. This is a NES emulator. Installed on retail systems since 1.0.0.
The titleID for "flog" is used by 3 funcs in qlaunch. It's unknown what exactly triggers launching this title officially. This can be run with unofficial methods.
The ROM is not loaded via FS but is embedded in the main binary.
"flog" == "golf" backwards. This runs the NES "Golf" game. {1/2}-player via joy-con is supported. Controls are "d-pad" buttons + stick, however motion control while holding the Z{L/R} button is also supported instead of using buttons.
It is currently known to be launched by setting the system date to July 11 and performing a currently unknown motion with the two Joy-Con.
