get yourself a EZFlash Vi and a 3in1 Expansion Pack. see info here http://www.ezflash.cn/products.htm and read the reviews here http://gbatemp.net/index.php?showforum=99
As many others have said stay away from anything with R4 in the name. I agree with what MaryD7 suggested.
I should have done my research first, but I suppose I have gotten some use out of my Super R4i even if its shit. Anyway, lack of research forces me to ask some (probably stupid) questions... Does there exist a flash cart that allows a DSi to play both NDS and GBA roms? So far I cant find anything and I would like to think Im good at finding things, so I assume no. Also, what is the best card on paper for a DSi? Aesthetics are a plus, and Im looking for something that is both easy to use and update. With everything thats out there its hard to just pick up a random cart and have it fit.
dstti plays in both ds lite, dsi, you need the slot 2 expansion pak for GBA games. http://www.ndscardshop.co.uk/index.htm got genuine cards from this site in 3-4 working days to the uk.
This is the kind of thread I was looking for, I'm having a hard time picking out a replacement for my R4DS, which was an excellent card for me, except for when they stopped putting out updates for it and it doesn't support some of the new games. So now I'm looking for a replacement. It would be nice to pick up something that also allows GBA games. I'm leaning towards the M3, since they seam to be around the longest, atleast from what I've seen, and I've never heard of EZFlash or DSTT until this thread. Who is the official M3 group? www.m3adapter.com? I know there are some knockoffs...
