Which R4 card? so confused

hello,
Sorry but I know there are a lot of threads as far as which card to get. After reading a good portion of them they go back and forth between R4i (gold, delux, rts, etc) and acerkart and talking about timebomb issues.

All I'm looking at doing is getting a cart that allows to play nes, snes, gba games and possibly 3ds games.


Help me, Obi-Wan Kenobi. You're my only hope.
