Firstly, how much do snes n64 games etc cost to download?
They go off "Wii points" these go from 400 to 1200 for some games
How many can i store on the wii?When bought via either the Wii Shop Channel or the Nintendo DSi Shop, 1000 Nintendo Points cost US$10 in the United States, €10 in Europe, £7 for Wii points (£9 for DSi points) in the United Kingdom, and ¥1000 in Japan. When bought retail, the original Nintendo Points Cards, which had values of 2000 Nintendo Points, cost US$19.99 in the United States, €24.99 in Europe, £19.99 in the United Kingdom and AU$34.99 in Australia.
Quite a few, but you can save them to a SD card. They are locked to the console.
Also by any small chance are these playable online?
Secondly are there a decent amount of good games?
