Since so many people ask how long a DS stays on with a flashcart in, why not simulate this with a simple homebrew app that saves the data to the flashcart's memory and dumps it as plain text in the .sav, or have some converter if needed, I don't know how the save system works. It'd be a simple app that would have few options (sound, no sound, no sleep, random taps to process data, random rendering to keep the CPU/GPU active). I think it'd be fairly simple for an existing homebrew dev to make such a tool, I can't imagine much work is needed. I'd do it myself but I have no idea how I'm a Windows developer, unfortunately. Any thoughts, comments, ideas?
