In the span of 6 days, I made a clone of the Lights Out game by Tiger Electronics, faithfully reproducing all 11 modes of play (yes, this includes the cube). All puzzles are the original puzzles from each mode. I'm pretty happy with the results; the only thing that bugs me at this point is that I have yet to figure out EEPROM saving, though I have some leads on that. In the meantime, people with emulators will have to use save states. It saves like a charm on regular flashcarts.
Without further ado, here's Shades On, release 1.0!
