Gradius Rebirth (WiiWare), Stage 1
Notice that the player pauses the game at the 1:00 mark to cheat and unlock more powerful weapons – possibly using the Konami code!
Update: Apparently, the title suffers some slowdown during a few portions, like in Stage 2 (5:30 onward). Also, we’ve uploaded a 12-minute video from Gradius Rebirth, but the encoding is a bit janky.
