I just read somewhere that certain (maybe all) passcards have really bad power consumption. I recently purchased a SC Lite + Super Key from tehcamel (who rocks), but my DSL was already flashed. I stuck the passcard in the DS to replace my Metroid Prime Hunters demo, just for the heck of it. Will this consume more power for some reason, or does flashme completely turn off the slot-1? Would it be advised to leave a commercial cart in the slot or no cart at all? I'm going for longer battery life, so keep that in mind when answering.
