As the title says, my EZ Flash Omega cartridges (2 units) experience freezing mid-game. I have tried most fixes that I have seen; formatting to the recommended allocation unit size for a 4GB memory card, cleaning contacts, using my own GBA game dumps, etc.

Since this happens on both cartridges that I own, I kinda think that my memory card is at fault, but is still kinda unlikely since I am certain that this card is authentic and has no bad sectors or anything. This also occurs on both my OG DS and DS Lite.

Assuming that no major hardware issues are present, what methods can I do to fix this entirely that you recommend? I don't want to struggle with my win streak in the Battle Frontier no more. Haha. Replies are appreciated.
