Will we likely ever see real time saving on gateway?

    Save-load states.. ? Or even speed up function?
    Would it be possible with current hardware?
    Have they voiced their will to make such thing?

    I heard they want to do something with saves, but not sure what they mean.

    Right around the cornerâ„¢
    They are talking about enabling save modding/cheating. I highly doubt we will see such features outside of an emulator.

    If it's possible within the software capabilities of the 3DS, then the Gateway can do it. They'd just have to make a process that runs in the background to allow for those features.

    Save / load state would likely require dumping much of, if not the entire, memory state. Don't know if that's feasible with this generation of handhelds, wrt size of storage vs. size of memory dumps.

    The Cyclo Team did it with the CycloDS, so... It could be possible, if the way they launch games allows for that, which it could, I think.

    SuperCards have Real Time save for the DS. And those save files are really tiny.

    Doubt it, it would require dumping the whole RAM used by the game onto the SD card, it would probably take too long to be worth it.

    NDS have 4MB of total ram, while 3DS has 128MB. see the difference?

    Just checked the Save State file for one of my Dolphin Emu games. 22MB. And it's a fully 3D adventure game. I seriously doubt any 3DS game is going to have larger files than that for a save state.

    Super Smash Bros on 3DS needs to reboot the 3DS into a mode that gives it 80MB of RAM instead of usual 64MB. I think it will be used.
    Plus, doesn't Dolphin compress the save states anyway?

    I have no idea how big 3DS ROMs are, but you can fit twelve 80MB saves into 1 GB, and I've never used more than 3 save states per game. a 16GB flash card is less than $10 on Amazon, so it's not like it costs very much to have tons of storage.

    I more so mean how LONG it would take. Dumping DS's RAM into those save states could take a bit, 3DS has much more.

    Not practical considering the size of RAM, but entirely doable.

    The faster CPU on the 3DS compared to the DS should make up the difference.

    The CPU has little to do with this, the speed of the bus is a bigger bottleneck.

    I think the determining factor is read/write, which won't be much faster than on the DS itself, while the RTS' on a 3DS would be much larger files.

    I thought so too, except that RTS on Dolphin is instantaneous, so I figured having a strong desktop CPU was the reason. But in case of what you say, aren't Read/Write times set by the storage media? So maybe an 80MB RTS will save really fast as long as your SD card is SDXC. I mean, cameras don't have a lot of computing power, but high end models that save large 20MB+ RAW formats can still do dozens of shots per second in burst fire.

    At the very least, a save state would require the 96mb of RAM used by most 3DS games. I guess it could work, but you'd be sitting there for a bit waiting for it to write. I wouldn't hold my breath.

    Also the new 3ds has more CPU/Ram right?
    Also if we have to wait like 5 seconds or even 10 that would work for me... Save states are important aside from internal game save function to me.

    The micro Sd cards I have go like 20-40 megabytes per sec so thats not the limiting factor.
