PaulGoes has released a new clone of a classic for the Nintendo Wii, here some more info:

Donkey Kong Jr In 1982 I got my first ‘handheld’ console: the G&W Donkey Kong Jr. In 1983, I programmed my own version for the TRS-80 home computer. And now I programmed this version for the Wii homebrew. Why? Because it is simply possible to do and a fun experience too! I got the trigger to start this at an information evening at my son's school. A student of de 'hogeschool voor de kunsten' was telling about game design. A girl asked him if it would be possible to program games for the Nintendo Wii. That question triggered me because the month before I softmodded my Wii.
