My sister want to get a wii with wii fit plus to get herself slim.

First, I want to know, what is the different between Wii Original and Modified?

My sister ask the shop seller and they said that Modified Wii sell RM 900++ which can read the pirated game disc but crack the firmware(?) only sell RM600++ only which read though the hard disk.


If my sister is going to choose modified wii, so what should she choose?
and what is original wii benifit?

sorry for my bad english, and i hope to get some answers here, thanks.
