PRG ROM Smiley Test for Quattro Adventure - NES

• PRG ROM Smiley Test

To activate the PRG ROM "Smiley Test" easter egg for this game, you will need to power on the NES/Famicom console while holding Up, Down, Left, Right, A, Select, and Start. Note, however, that it is not normally possible to hold all four D-Pad buttons without specially modified controllers; standard NES/Famicom controllers will not work.
