So I got my Acekard, and I'm thinking about getting an EZ-flash 3in1 to be able to play GBA games and the like, but I'm having some doubts: 1. Does the Acekard has any added functions with the 3in1? I'm talking about the depleted battery issues that the expansion packs tend to have. I was reading the akaio wiki, and I understood that it is possible to back-up the sram data with the Y button. Does this mean that you can save even with a depleted battery? 2. Have the saving issues of metroid fusion/zero mission been solved? 3.Would it be more recommendable to get a EZ-flash IV? I've read that with in-game softreset you can save your game regardless of the battery state... Thanks in advance!
