The information here is taken from the AKAIO forums and here. And yes, I know there already is one of these, but it was last updated like, 2008. The Acekard Frequently Asked Questions Thread Q: AKAIO isn't working on my Acekard, what do I do? A: Most likely, your Acekard is a clone or fake, read this post and it should clear things up. Alternatively, download the latest version of AKAIO from akaio.net, do a full format of your card with the Panasonic SD formatter, and place the __aio folder and akmenu4.nds on the root of your cart. Q: I recently updated my DSi to 1.4.1, and now my Acekard doesn't work! Help! A: Read my help guide on this question. Q: I upgraded to AKAIO from the official firmware, and now my saves won't work! A: Prior to v4.14-ish of the official firmware, the save extension .nds.sav was used. Simply rename all of your saves to "Game XXXX".sav rather than "Game XXXX".nds.sav. Q: I heard that I can play GBA Games on my Acekard, how? A: You will need a EZ 3-in-1 or a similar Slot-2 expansion pack, meaning that it will not work on a DSi(XL/LL). AKAIO supports the EZ 3-in-1 natively, all other expansion packs will require Rudolph's GBA Exploader. Q: My GBA Saves aren't working on my emulator! A: AKAIO uses a 16-bit header. You can strip the header to make it work. Search Filetrip for a program that does exactly that. Q: Moonshell 2 isn't working with AKAIO, how can I fix it? A: Delete logbuf.txt in the moonshl2 folder. If it still doesn't work edit the moonshl2.ini file and set the value for AlwaysDisableCheckedDisk to 1. Q: What's the difference between the Acekard 2 and the Acekard 2.1? A: The Acekard 2 suffered from a soldering error in the manufacturing plant, causing it to have a FAT error. The Acekard 2.1 fixed this issue. Extra information The Acekard 2.1 also had a different chip that took less power. Q: Oh, ok, then what's the difference between an Acekard 2.1 and an Acekard 2i? A: The only difference is that the Acekard 2i works on a DSi. Q: Game XXXX fails to load or play correctly but I've got Anti-Anti-Piracy enabled, what's the problem? A: This is usually due to microSD latency speeds, anything under 8273-ish will not work. Q: Can I use Wood RPG on my Acekard2(i)? A: No. Use AKAIO instead, they look the same and have roughly the same features. Q: How do I turn on Anti-Anti-Piracy? A: With the game selected, hit Y, hit Y again, and scroll down to BypassAntiPiracy. Q: What's the difference between AKAIO and the Official firmware? A: The AKAIO firmware provides an option for an Acekard loader that is frequently updated, whereas the official firmware is not, and has better compatibility and more features. Q: I heard about this thing called wireless updating, what exactly does it do? A: Wireless updating automatically updates the USRCHEAT.DAT database. It can be turned on in Start>Wifi Update. Q: My Acekard boots up a game automatically, what's wrong with it? A: Autorun is turned on. Press and hold B whilst the Acekard boots up and then go Start>System Options>Default Patch Options>Autorun>Disabled. Q: I heard that there are a number of R4 clones that support AKAIO, what are they? A: The R4 Ultra, which is essentially just a rebranded Acekard (r4ultra.com) There seems to be a lot of confusion as to which R4i Gold supports AKAIO. R4i Gold (old) ===> Supports Wood (r4ids.cn) R4i Gold 2.0 ===> Is a R4 Ultra clone, supports AKAIO (com[/b]]r4ids.com) People that have contributed with this FAQ Rydian A Gay Little Cat Boy Hakoda dewback ShadowSoldier If there are any other questions post them in here and I will add them to the list.
