Hey guys. I've currently encountered an issue when using the GB Cart Flasher v1.1. Every single time I use this application for my friend's copies of Pokemon Red and Pokemon Silver, for some reason when I select the 'readRAM' feature it would state on the application the extraction was successfully but would produce a blank .sav file and deletes the save files stored on the cartridges. I'm not too sure as to why it does this as I've tested the device and application with my cartridges and, it would always successfully produce my .sav files without deleting my save files from the cartridges. Now, just to add on, the difference between my copies of games and my friend's copies are mine have new batteries installed into the cartridges when I had purchased mine via online whereas my friend's copies have there original batteries as well as not been taken cared off by giving them a case. He's had those copies since the release of the games and have NEVER opened them up. I can only assume the reason as to why his copies get corrupted during the extraction phase is due to having a dirty motherboard and potentially a battery failure. Yes. Before anyone asks, I have tested his cartridges out by creating a new save file and repeatedly saved the game and, rebooted the game to see if the save file were to remain. Any ideas from other people's knowledge or experience would be much helpful as I've never opened up a Gameboy cartridge have even attempted to replace the batteries or them or even to clean the motherboard. Please and thank you!
