Yosaku, a b&w remake of a 1979 arcade game by Orca, a Toaplan predecessor, that appears when you put The King of Fighters: Battle de Paradise (NGPC) in a black and white Neo Geo Pocket.

The arcade game was based on a popular song about a woodcutter, performed by Saburo Kitajima:

Update: the thing I was missing--and arcade flyer scans bear out at least the publishing part of this--is that 1979 arcade Yosaku is actually credited to SNK as developers and publisher. (Was reminded of this by Brandon Sheffield of @necrosoftgames, who wrote the Yosaku entry for the Museum section of SNK 40th Anniversary Collection!) So why does the arcade Yosaku's title screen credit "OLCA CORPORATION" with development? Was it a joke? Were the Orca Corporation people working at SNK at the time?
Update update:
Ah, some of the comments (Google translated from Japanese) below that one OLCA CORPORATION video,

mention that Orca Corporation produced a lot of pirated boards; so this could have been a pirate board by Orca of the SNK original. Whatever this version is, it has hazards also dropping from the tree branches! = o
One of my first thoughts upon meeting Loop was that they would be BESTIES with Eyala. Like literally gossiping about the universe kinda besties. Love that for them.
