I have been researching information on flash carts like the R4DS which allow you to do more with your DS than you could before. The only problem is that I have a limited vernacular when it comes to technical jargon and I don't understand much. I would really like to do this mainly to install SNES and NES emulators on the DS (which I also have no idea how to do) because to me the DS has a limited selection of really good games while the SNES had a wealth of fun games. I would really like to know which Slot-1 flash cart is the best one to use (I have heard alot aout R4 but also that there are better ones), which Slot-2 flash cart is good to use so I could play GBA games, can you have both running at once and how do you set them up. I also read that you can not use Slot-1 flash carts to emulate GBA games, is that still true? Also, does your DS have to be plugged into a computer to play any type of games you have installed onto the MicroSD. I just have one more question for now, sorry if I am asking alot I don't know much, but I was wondering what games these flash carts can play, not specific games but the systems that can be played like NES, SNES, playstation, etc. Any help is very much appreciated.
