I have a relatively new EZ flash Jr that I bought about three weeks ago from a vendor. It worked great until last night. I cannot get it to load anymore. I have tried multiple gameboys, (TFT backlit GBC, original GBC, GBL, GBA, SP, and two Pockets) it does the same thing on all of them. I have formatted the micro SD probably a dozen times now. Copied the right files in the right places. Using FW4. What happens is it boots up and when it hits the SD reading screen it will either scramble the screen, turn black, reboot with a scrambled nintendo logo, or show this weird code that says xyz~and a delta symbol. Micro SD is a Sandisk Ultra Red. 32KB cluster FAT32 when formatting. Cart itself looks fine. No bad traces or popped up pins. Also cleaned the SD slot just to be sure. Have no idea what happened to this when it was running flawlessly until yesterday, and now I can't even get it to do anything.
