I never buy the ‘backups’ excuse for modding your console. It’s about buying 20 pirated games from Dodgy Dave down the local market for £15, surely. Who backs up their games, seriously?
Anyway, there are reports that Nintendo’s Wii has been well and truly hacked, with a modchip coming out imminently called the Wii D2C Modchip Actel. However, it only works with around 80% of region-protected games, and it requires you to do complicated soldering stuff to install.
