I think I’d consider this more along the lines of homebrew unless it gets an official, Nintendo-licensed release for the original hardware. Star Fox 2 is in a similar boat since Nintendo did officially release it in 2017, but only as a bonus for the SNES Classic and later NSO.
Since this is an “official” game, does the GameBoy now beat the PS2’s record of FIFA 14 releasing 13 years after the PS2’s launch?
