Pokemon black/white 2 acekard 2i black screen

[sxore]

I've tried so many roms; U clean, U patched, J clean, and J patched. I have no idea how to fix this. It'll show the start up cut scenes then it'll freeze on a black blank screen for about two minutes while playing distorted music. After waiting out the black screen the rom works perfectly fine, it's just REALLY annoying. Could someone help me? I've tried disabling soft reset, cheats, and ap bypass in the settings. All result in the same thing.

So the game freezes for 2 minutes before loading?

I suspect that there may be an issue with your SD card. As you move ROMs and other files around on your SD card, the files can become fragmented over time. SD card file fragmentation can cause games to run slowly, freeze, and have other random graphical glitches during game-play. I would strongly recommend that you copy all of your files off of your SD card, then format your SD card, then put the files back on it. That will solve any file fragmentation issues.

If you still have trouble, please let me know.
