MSX games seem to be compatible with the Wii's USB keyboard connection with the first game, Aleste.
The MSX console, according to Siliconera was used as a gaming device in Japan, offering keyboard control schemes with some dependant on the alphanumerical keys.
Aleste, recently released for the Virtual Console service, allows for four control schemes: Wii remote, classic and GameCube controllers as well as support for a USB keyboard plugged into either of the Wii's available slots.
With games now supporting keyboards as a means of control, would we be seeing more advanced keyboard functionality and classic PC ports on the Wii?
