Hi, i've been having a problem with my EZflash card IV on my GBA SP. You see...i have this flash card for a about 2 months now and it was working perfectly, but today i decided i wanted to play a GBC game so took of the flash card and put in the other game, that also worked fine, but then when i put the flash card back it would freeze the "gameboy" screen without the "nintendo" under it.I tried everything to make it work: blowing, cleaning, checking if there was a obstruction, checking if it was properly put in but doesn't work. I tried other GBA cartridges and they worked fine so it seens the problem its the flashcard. Any ideas on what i should do guys? any help will be greatly appreciated.
