Updated your dsi/3ds system before your r4i, so you cant play it? Well, instead of having to get another ds lite or dsi/3ds which hasn't been updated, you can get an action replay dsi. It is a cheats system where the ar dsi card has a card slot, and you put the game which you want to cheat on in the slot. But if you put an r4 in the slot, obviously it won't have cheats but you can still boot it regardless of your system's or r4i's version! And, of course, it will work if you already have an action replay dsi.
