As another weekend draws to a close it can be nice to catch up with some retro classics and fascinating facts. With Super Mario having its 30th Anniversary this year and The Legend of Zelda due to hit the same landmark in 2016, they seem like good topics.

Once again the Did You Know Gaming? YouTube channel has been collaborating with other video creators to look at these classic IP. First of all one of our old favourites, A+ Start, shows off some Mario glitches covering Super Mario Bros. through to Super Mario 64.

Next up is an Easter eggs video covering the first three home console games from the Zelda franchise; a few of these facts, particularly around the NES games, were new to us.

Videos such as these are always fascinating; we often wonder how a lot of the glitches - in particular - are even discovered. There's nothing that dedicated gamers can't find, it seems.
