From what I heard, 3DS cards could be dump through a DS Lite, for now, 'saves' by cutting off that ledge that prevents it from being inserted through a DS handheld.
I'm sure it won't be long before we see an "R4" type of flashcart or if they hack the OS to load code and from there 'jump' to a rom dumper, or just dump it manually using the RAM.
The only real problem with the actual ROMs is emulating the gyroscope and accelerometer, and also, the autostereoscopic effects. Anyway, even if the audio was able to be ripped, how long would it take for the plugin for Winamp to be developed?
i thought the same, but apparently that's not necessarily true. a little bird told me that 3DS games will still largely use sequenced music. while the cartridge storage has no doubt increased and streamed soundtracks will be more common, there was a data bandwidth limit with DS cartridges that's still present in 3DS, which makes using streams no soft option.
there are certain advantages to using sequences anyway, they're more flexible with game dynamics. (for instance, it's totally unfeasible to do something like this with streamed audio.) i don't think we'll see sequences disappearing any time soon.
anyway i am hopeful that games will be dumped and music ripping will begin :)
