I want to get a good priced flashcart mainly for use of the Pokemon series (Heartgold/silver, black/white...etc) I am currently looking at this one http://www.r4-usa.com/products/R4-DS-for-DS-and-DS-lite-consoles-%252b-2GB-Micro-SD-.html and I am wondering if this would be sufficient and work fine with my needs. I have a NDS Lite just in case that matters too much. Thanks.
If you were able to use the Wood firmware with that cart then i would say yes purchase it, but it is not listed as such so you would be taking a chance with it. I would suggest you purchase an R4i from r4ids.cn <- (and only an R4i associated with that website) or an acekard 2i.
So I bought the flash cart from the link you gave, but I was wondering, can you get on Nintendo WFC with it?
