Flashmasta v5.1 Corruption and Deleted Saves

[lynxtosg]

I've had the Flashmasta for a few months now and have noticed several games getting corrupted when transitioning between scenes and have had save files completely removed after the corruption. When I say corruption I mean severe graphic distortion with no recovery except power cycling. Is this common for other users? I'm using the no-intro set and programming over linux. My battery is fresh during these issues, about 70%.
