Chip 'n Dale: Rescue Rangers 2 is quite an improvement over the original Chip 'n Dale in terms of graphics and a whole lot of other things. Thankfully, the original game's solid controls haven't been changed. The plot of this game is that Fat Cat has stolen the Pharaoh's Urn and wants to use its power (for evil purposes, of course).
This run only uses Chip. It's an improvement of 01:19.40 over the previous "1 player" publication, through careful optimization, some new tricks and manipulating the bosses.
See this run replayed on an actual Famicom console.
