This guide is about buying Flash carts from eBay. Some people may not trust those flashcart websites, and eBay usually is good with consumer's trust. And that is why this guide is useful. Some keywords are: DS Sd card adapter : Some people sell DS-Mode flash carts under this search query. I have found R4 Revolution SDHC Dual Core, and R4 SDHC Gold listed today under this. also for some reason i found results for SuperCard GBA. [Insert card brand name here] if you want an acekard, search acekard. This is how i got my AceKard 2i from ebay, it was searching for AceKard. Many flashcarts can be found like this. r4 card: the r4 has basically became ubiquitous as flashcarts for the DS line of products. Search for it and you get some results. It is better to get it from Buy It Now, but if thats not avaliable, then try to bid on it.
