    I currently have the EZ Flash IV and using that in my GBA Micro. The problem is, it won't save because of the battery being dead.
    Which good flash carts out there don't use a battery to save your progress?

    Also, can anyone post a pictured guide on how to replace the battery in the EZ Flash IV, just in-case I can't find an alternative flash cart?

    every gba cart uses a battery to save. It's simple to replace the battery. I got one on ebay and removed the contacts with a razor and didn't even have to solder the new one

    Exception made for Supercard SD.
    I think the M3 Perfect CF also is battery less but I can be wrong on that.

    sram requires being fed continuously by electricity to keep data (even if it uses tiny amounts) = most GBA carts used sram. However, like newer DS flashcards, they grab a certain amount of data from memory (namely, the save area located physically on the flash chip) and then export it as an external save file, so it should be possible, IF the team would develop an update

    I could be wrong but I thought I read here once that it was possible to save on the EZ Flash IV without using the battery, ie. direct write to the mini-SD or something like that. I don't have details, and I could be wrong. But I'm almost sure I've seen that described before. Maybe someone else can explain?

    Does that include the Mini SD version? If so, I think I'm going with that.

    Even if I wanted/knew how to replace the battery, anytime the battery dies, there's no way in backing up my SAV files on the EZ-Flash IV and I'll lose SAV files everytime the battery dies.

    Mini SD version has the battery iirc.

    Supercard SD doesn't have one.

    CF as well (there's no room).

    Supercard is not worth it.
    Use in-game soft reset on the EZ4 = Problem solved.
