Hi, I just got an EZ Flash IV micro-sd model and all seemed well until I tried testing it with Mother 3. What happens is that the game copies to the NOR memory with no issue. However when you run the game, it only gets as far as the GAME BOY PLAYER logo and then goes to a white screen with horrible digital noise coming out of the speaker. This would indicate to me that maybe some blocks of the NOR memory are damaged / corrupt and that the NOR chip is faulty? I just want to see what people think before I send it back as faulty. I have tried both the normal clean japanese version and also the english fan translation. I patched both with both the latest EZ flash patcher and the community ezgba patchers and both produced the same issue. I even tried with unpatched roms just to see if they would work (without being able to save). Everything I tried produced the same issue. The unpatched rom has the correct md5 checksum of af8b0b175f7ec8914cb87b3161ba1aaa before anyone says it is a bad dump. I can provide checksums of the ez client and ezgba roms if that helps. I don't think it is an issue with the rom though but the NOR memory of the flashcart. Or is it a software issue? I have tried reformatting the NOR memory several times (pressing start in the appropriate section of the flashcart menu). I have also tried various levels of FW, including 1.76, 1.77, 1.78 and 1.74. All exhibit the same issue. Smaller games seem to work in the NOR memory but they are probably not being loaded into the damaged area of the memory. I also tried Kingdom Hearts: Chain of Memories, another 32MB game, which loaded fine and seemed to start fine but that doesn't rule out the memory being bad in my mind because it didn't necessarily try to load the "bad" section of NOR memory for the 2 minute test I did. Is there any way I can test the memory? What do people think? I am thinking I will have to return it and hope the replacement isn't faulty. I just posted here to make sure I haven't missed out anything stupid.
