hardly MASSIVE....its a slight change from normal, set up emunand and update, (takes like 20 mins max the first time around, and then updating is just the same as with a properly updated console, and online games takes like 20 seconds to patch the rom if you aren't dumping your own carts and 2 seconds to rename the rom to .3dz if your dumping your own cartsBut no eshop... or online games (without a massive amount of work to get it right)...
