Back in late 1996, with the Nintendo 64 fresh on Japanese store shelves and Super Mario 64 thrilling gamers, Nintendo pushed out a unique title on the aging Super Famicom called Marvelous: Mouhitotsu no Takarajima, which translates as Marvelous: Another Treasure Island.
Notable for being the design debut of Eiji Aonuma - the man now in charge of the Zelda series - this unique release mixed RPG elements with point-and-click mechanics to create a totally unique - if short - experience. It also looks and sounds a lot like A Link to the Past, which is no bad thing.
The game never got an English localisation due to its late release in the lifespan of Nintendo's 16-bit system, but it has been translated by fans in the years since, and a fresh patch - which includes graphic hacks to replace every bit of Japanese text into English - is now available. If you own a Retron 5 or Retro Freak, you can apply this patch to the original game cartridge and lose yourself in one of the most original games in the Super Famicom library.
