U Can Beat Video Games (their YouTube channel) has only been around for a bit over a year, but they’ve already covered a lot of challenging games. It serves as a complete video playthrough, often revealing all the game’s secrets, and has remarkably restrained and helpful audio commentary by YouTube standards.
UCBVG videos cover the entire game, and can be long. The most recent, the covering A Link to the Past with a second part, is nearly two hours but it uses YouTube’s timeline annotations to mark any potential trouble spots you may have. Even if you’ve mastered the games he covers, I find it relaxing to watch anyway to refresh my memory on these decades-old amusements.
To date, UCBVG has covered 70 titles across the NES, SNES, Game Boy, and Mega Drive/Genesis. Some highlights include their videos on the original Teenage Mutant Ninja Turtles for NES (the first game on the channel), Mega Man I, II, and III, The Legend of Zelda, its second quest, and it’s sequel, Ghosts ‘n Goblins, Legacy of the Wizard (a.k.a. Dragon Slayer IV), Castlevania and Simon’s Quest, Blaster Master, Punch-Out!!, Ninja Gaiden and its first sequel, Clash at Demonhead, Metal Gear, Crystalis, Wizards & Warriors and its sequel Ironsword, Dragon Warrior and Final Fantasy (in two parts), Actraiser, The Guardian Legend, Kirby’s Dream Land (including Extra Mode!), the weird and unique The Magic of Scheherazade, Sonic the Hedgehog, and even the notorious Battletoads, among many other games.
They update weekly, so why not take a look!
