Hi everyone!
As you can see, this entry is a bit "special", as it was created for the Super Game Boy device. But this is not a regular Game Boy game: it relies on a "hidden" feature of the device to control and display actual SNES sprites in addition to everything rendered in the GB screen area.
It also also uses other SGB features to colorize the screen and play sounds using the SNES sound chip.
You'll need a SNES + SGB or a SD2SNES / FX Pak Pro to play this game, or you can use a SNES emulator with full SGB emulation like Higan, Ares, BSNES or Mesen S.
I hope you'll enjoy it, even if it's not a "standard" SNES game :)!
