Is it possible to download games to pendrive then connecting the pendrive to wii usb input to download the game? That is if the internet connection is to far away from the console and dont have wireless connection.
No, maybe later after a firmware update.
The wii usb port do nothing as of now, they only output voltage. The wii would not do anything to the pendrive.
If you don't have a wifi connection available, then you should get the ethernet adapter and run some ethernet cable.
