Hi there everyone, I've done some serious digging around recently since I had bricked my Acekard2i. There was a rather big argument between Acekard users and their cards getting bricked and not getting bricked while using the same game. I myself decided to do a little testing after I had the incident myself. Games that are 512MB brick Acekard2i... Well not completely and not for everyone. What I noticed while reading through several threads between multiple forums, is no one was giving enough information and everyone was calling each other a liar. In so many words. Well I decided to end this thought for myself and others who didn't figure it out and are still sad about not being able to play some games. MAINLY because no one wants to have to buy yet ANOTHER flash cart to play just ONE game. It's a hassle and defeats the purpose of buying the first flash cart in the first place. The game in question I am using an the example, as this is the game that I had the incident with: Love Plus Plus. A Japanese "Date Sim" Sequal to the head turning Love Plus. The game is 512mb in size the largest size an NDS game is capable of being. Going through I decided to give this a major testing. I used 3 NDS files each from a different download source. I also used 1 DSi, 1 DSL, and 1 DS Phat. This is my result. The Hardware [aka the version of DS you are using.] Is irrelevant to the outcome. The MicroSD card however is the KEY. When playing the game on any system using a MicroSD card formatted in FAT32, on each system resulted in a BRICK. After unbricking the Acekard for the third time, I reformatted my MicroSD card to FAT [also known as FAT16] and tested again. When playing on any system, Using a MicroSD card formatted as FAT, you do NOT get bricked. So looking back at the issue I saw, no one who got bricked ever mentioned what their SD cards were formatted as. In kind those who were not getting bricked ALSO did not state what their SD card was formatted as. I am going to say thank you to Bloodlust who posted in one of the threads that Formatting to FAT16 will fix the issue, as it was this statement that I could not put much faith behind as the statement wasn't too indepth and had no sources behind it to state where he got the information or anything else. And Thanks to tk_saturn for his Updating AK2i guide for without it I am sure a LOT of people would have likely thrown out their acekards after a brick. So final words: To play 4Gbit games [512mb] you must have a FAT formatted SD card.
