Slot 2 device reccommendation

*Firstly sorry if this is in the wrong place*

OK then, I'm looking into getting a slot 2 device capable of playing GBA Roms. Some ideal features would be that it could also play DS Roms perhaps, and also work in a GBA console (for the GBA games of course), and also be compatible with the R4.

If a product that can do most of that list actually exists, I'd like to hear some examples from you guys

 

Well, since you already have an R4, why not pick up an eWin expansion? It's pretty cheap, since it has no memory to write to other than RAM, but using Rudolph's GBAXploader, you can set it up to play GBA games, leave them stored in RAM (in case you're doing the FFTA2 Libra load, or Pokemon swapping to D/P), or you can flat out clean it out to use as expansion memory for DSHexen or the Opera Browser.

Other suggestions might entail the 3-in-1, but I personally don't know much about it.

 

Try EzFlash, or Supercard or something. Check out the Reviews on http://www.gbatemp.net/.
