LONG VERSION A few days ago I tried to run a patched Pokemon Black 2 on Acekard 2i for the first time and the game froze quickly. When I turned the system back on, the Acekard 2i was no longer recognized, after at least a year of working perfectly. I tried inserting it into THREE other DS systems (a DS phat, a DS lite, and a 3DS), and none of them recognized the Acekard 2i anymore. I assumed it broke somehow; I don't know if it has anything to do with the ROM i tried running, but.. In any event I purchased a new Acekard 2i. It's recognized by the DS phat, the DS lite, and the 3DS, but /STILL/ not the DSi XL. And when I say "not recognized" i mean "there is nothing inserted in the game card slot." I find this really peculiar. I should mention that the DSi XL will recognize an OLD acekard 2 I have (not 2i), as well as any other cartridge i put in. SHUT UP AND TELL ME THE SHORT VERSION My DSi XL DOES recognize an old "Acekard 2" in the slot. It DOES NOT recognize an "Acekard 2i" which works with all other DS models I've tried, including the 3DS. I think something is wrong with the DSi XL and I'm not sure how or why, or what I can do to fix it. THERE'S MORE? I am running System Firmware 1.4.4U. I have included all of the appropriate updates and the latest version of AKAIO on the SD card, just in case, and still cannot even get the DSi XL to recognize any Acekard 2i. I have searched the forums but haven't found a problem exactly like mine; I've tried the solutions to problems SIMILAR to mine to no avail. Thank you.
