    Go to the address 0x1B0 (between the header),and there put this:

    52 41 XX 20 00200001 002003FF

    green part = first memory address
    red part = The last memory adress.
    XX = (in bits) 1x1yz000

    set x to backup on,and set yz to 10 if even address only,11 if odd address only and 00 if both even and odd address.

    Now when you want to write into the sram,just use something like move.b #$01,$200001,you get it,just write between the address 200001 and 2003FF and read from they.

    Good job! I used SRAM in Timezones if people don't remember. It's a useful tool for hacks. I recommend it!

    I think it's used for saved games in S3.

    Nothing that concerns this place in the least.
    Yeah, and they're the save files that have filenames like "Sonic3.srm".

    Doesn't 'have' to be battery. That's the method that was used by probably all the carts because it's easy and cheap. However, I don't like to call it battery RAM because that's not 100% accurate to what it really is at heart.

    You can't argue that it does need a battery to stay working.
