    I'm pretty confused now as this makes no sense.

    I'm going to use Mario and Luigi Dream Team Bros as an example. The NFO that came with it states that the game is 8GB: [​IMG]

    Yet the size of the rom is only 1GB: [​IMG]

    I tested it and it seems to work but why is it only 1GB if it's supposed to be 8?

    They are 2 completely different units

    the Gbit = GigaBit
    the GB = GigaByte

    1GB = 8Gbit

    Bits and bytes. Learn the difference.

    He probably just overlooked it. No need to be preachy.

    Just a FYI, most 3ds games are going to be in that 1-2GB range. I don't think there ever will be a 3Ds game that is over 8 GB in size.

    I knew it would be something dumb like that. -.- Why can't people just learn to use one or the other...

    Yeah, I overlooked it. I've see the two before but being that everything is usually measured in GB and like nothing in Gbits I just went straight to gigabytes.

    Eh, internet speed is measured in bits. I wouldn't say that it is "like nothing". Many things have to be in bits and not bytes; like IP addresses for instance.

    Internet speed seems more like a gimmick to make it seem like you're getting really fast internet but in reality it isn't.

    Most things like file sizes, HDD space all measured in GB, it's used a lot more in daily life.

    Yeah well I have no answer now. I was going crazy when I saw some games are 32Gbits thinking it was 32GB...

    Yes, most things for certain are. My point was that there's a difference and there is a reason not everything is in bytes.

    You think it is not a gimmick that became tradition here?

    I would be careful using hard drives as an example - they deliberately use 1000 rather than 1024 as the multiple (see IEC byte units or mebibytes if you want a slightly better search term).

    As for the max. I am not sure, obviously it is near infinite if they decide to bring back bankswitching or use some form of sector/offset addressing but 3dbrew is rather lacking on any specifics in terms of where size markers might be and how many bits they have to address with.

    Away from this shithole
    You are using a 3DS, therefore the correct measurement is 4096 Nintendo Blocks :D

    I sometimes think ISP's use Gb's to trick consumers into thinking they have "Gigabytes" of internet speed, making them think it's much faster than it actually is.

    Time to lock this. Nothing left to say.
