I haven't got any flash carts yet but I'm reading that flashcarts may need hardware revisions. R4i Gold Deluxe 3ds is like $20 cheaper than Gateway/Mt-Card but it can't play and save card type 2 games yet due to hardware limitations. How many Card type-2 games are there and will the latest games use card type-2 saving also? If R4i Gold Deluxe does get a revision later on, would the price be similar to that of Gateway and making that a bad investment on my part? Is gateway future proof?
