Hi. Just wanted to post this topic as I'm noticing a few problems with my Acekard 2i. I recently bought a Nintendo DSi XL and an AceKard 2i to go with mainly for the super Spectrum emulator ZX DS (which looks amazing on the big screens BTW). However when I run certain DS software on it I am encountering slowdown. Metal Slug 7 is the prime suspect here.. For some reason when the screen gets packed it really chugs. So I initially looked this up on the internet and didn't really find much info other than learning about Micro SD Card speeds. I noticed that mine were all class 2 so I though this was the problem. So i go onto Ebay and buy a class 6 8gb Micro SDHC and yet the same thing happens. I find it bizarre that games like Sonic and Sega All stars Racing is very fast 60fps, and that other games like Geometry Wars Galaxies which is also pretty hectic is the exact same as my original cart. What could be going on here guys? Can anyone help me? Many thanks.
