Any hidden gems for the Game Boy?

[VenomMacbeth]

Thanks for all the suggestions, guys.

So I believe I may have unearthed something akin to a holy grail...Battle of Olympus, one of my favorite NES games.  I just discovered it was ported to the Game Boy!  I can't seem to find any copies for sale, though...is it particularly rare?

[EDIT] Used ebay international & found a copy for sale in Germany.  Mine nao!

Trip World is a pretty damn good platformer for the Game Boy made by Sunsoft. It has only been released in Japan and Europe though, and is quite hard to find.

I like how GB games that were "ported" are really totally new games. Such as the Contra and Ninja Gaiden games. Theres tons more that are different than their console counterparts.
