    Hi guys.

    If i use R4 with 2gb SD, it counts the ROM Size or the "true size" when i upload ROM to it?
    Example:

    EBA looks like 128MB on my PC, but the ROM Size is 1024MB.
    or with Tony Hawk:
    its 67MB on PC, but the ROM Size is 512MB.

    So what can i do? I has G6DS Real, it counts the ROM Size. But what about R4? I can upload 16 128MB/1024MB Roms or just 2?



    P.S. Sorry for my poor english :) Hope you got it.

    I think you're getting confused by bits and bytes.

    Rom sizes are specified in megaBITs, computer filesizes are measured in megaBYTES. 1 byte = 8 bits, so a 1024Mbit ROM has a filesize of 128MBytes. The file does not change size, the only difference is the unit used to specify the size.

    So, if i have a 2048 MegaBYTE MicroSD, how many 1024 megaBIT rom can i use on it? Just 2?

    15. Because the rom file size is 128MBytes.
