like the progress bar in Crown3DS ?
Nope. I'm part of the Pokécheck team and I know there's actual progress.
We were the ones who made the initial exploit public (that spawned instacheck, battle analyzer, and this thread); we just aren't ready to let people know yet.
For the record, Gateway is about to release two relevant features:
Compatibility with Card2 games, making Pokemon X/Y compatible with the card.
Ability to dump retail cartridges.
Being able to dump a Pokemon X/Y cartridge allows us as well to dump the save within the card, which opens the possibility for the next Pokesav/Pokegen. The only inconvenient left is the save encryption, something that I personally believe it's a lot easier to overcome than encrypted packets.
It's still better/easier to decrypt traffic than it is to decrypt saves on hacked consoles. Just a single packet of data compared to an entire save file? Plus you wouldn't need a hacked console!
