Everyone keeps telling me to buy a DS flashcard

[Ashura]

Acekard 2.1 with AKAIO firmware (currently at 1.6 rc2) is the best budget flash card IMO. Normatt and his team update AKAIO's loaders regularly. If a game doesn't work properly on an Acekard, it will work in a newer, more compatible loader within 3-4 days. It has fully customizable skins, wireless updating, up-datable cheats, high homebrew compatibility, and amazing ndsrom compatibility. I'm not alone; it won GBAtemp's "best DS flashcard of 2009" poll, with 40% more votes than the runner up (CycloDS Evo). Best of all, it only costs 15-20 dollars.

I've owned one since August 2009 and it hasn't broken itself yet.
