So, I've had some troble hunting down some GBA games as I've recently moved. One of my existing launch period game's running out of it's battery and I've been thinking of getting the 3in1 as it's pretty cheap and buying used games at a high price doesn't profit the devs anymore. I just have some questions about the saving as I'm one of those guys who want to have their saves last years and years if only for nostalgia purpose. So, put simply the am I right in saying that the working battery is always needed for saving and loading the gba game saves, but the saves itself are automatically loaded and saved onto my wood r4 card? So if my battery runs after maybe a year of use I just replace it and continue as usual without losing any existing save data. I can easily backup the saves by just copying the .sav files to computer? I'm supposed to use the latest Exploader to load the games to the NOR? EDIT: To clarify, I have a DS Lite, original R4 with WoodR4 and want to hassle free gba experience without having to worry about losing saves.
