Wasn't able to try this one, as I don't have a SGB, but interesting idea.
Hi!
If you have a SD2SNES or a FXPakPro you can play the game on real hardware without a SGB, as this flashcart can fully emulate a SGB1 or 2.
There are also a few emulator able to run this game (Higan, Ares, BSNES and Mesen 2.0, including their RetroArch cores)
