There are a few different ways to download and play Sonic the Hedgehog games on your computer or game R4 Cards. Be careful where you download from, however, because some downloadable games may violate copyright laws.

Connect your Nintendo Wii to the Internet and select the Wii Shop from the main browser window. Connect your Wii with a USB to Ethernet adapter if you don’t have access to a wifi network at your home.

Use your credit card to purchase points that can be redeemed for Sonic games. Usually, these games will cost between 500 and 800 Wii points, but the smallest amount of points you can buy is 1,000.

Navigate the Wii Shop channel and find Sonic games that you’d like to play. You can sort the available games by counsel type or production company to help you refine your search. Select all games made by Sega to find most Sonic games easily.

Exchange your Wii points for Sonic games and then wait for them to download. Games are saved directly to your Wii’s internal hard drive and can be found on the main browser screen. If you need to erase a Sonic game to free up more space on your Wii, you should be able to re-download it later.

Find an appropriate console emulator for the Sonic game you’d like to play. Early games were on the Sega Genesis system, but you may be able to find a working Sega CD emulator to play other Sonic games.

Search for Sonic ROMs to download. Emulation sites are often shut down due to copyright issues, so you may run into lots of dead links. Add the names of popular uploading sites, such as Megaupload or RapidShare to help find current links (see Resources below).

Open the ROM image with your emulator to play the Sonic game after you download it. If the game doesn’t work, try using a different emulator.

Open the ROM’s preferences and adjust the control settings so that you’re comfortable playing on a keyboard. You can also buy a game R4 Card controller, but they might not work with all emulators.
