I've had my G6 for some time now and haven't experienced even the slightest problem. Also, from reading the majority of the posts here I realize that most problems people have are based on a few things. So here are my views of the situation. 1) Never ever use the Trim Rom feature of the U-Loader. Ever. (Why someone would want to use this is beyond me... I have 6 non-trimmed roms on my cart now, what do you want? 12? Why?) 2) Do not use the Soft-Reset feature either. There seems to be a problem with SRAM management when you soft-reset back to the menu after playing a game. This might mess up your saves. 3) Always use the U-Loader to put roms onto your cart. 4) Always use the "safe remove" feature of windows, when you're removing your flash cart. If you're in linux, unmount the USB drive before disconnecting. 5) Try to use "clean" roms. That is, try not to use trainer-patched roms, no-intro-patched roms, etc... 6) Do not compress roms onto your cart. Hope the above helps.
