Am I imagining it, or does the DSi's battery charge not last as long running with an Acekard and AKAIO? It used to be that I could leave my DSi in suspend mode (lid closed on an active game) for days. However, with an Acekard and AKAIO I am lucky if the battery lasts over night. This is on a relatively new DSi (3 months old), so the battery should be in good shape still. I will have to do some tests between an actual DS cartridge and the same game on an Acekard.
