I would recommend trying this app first before converting your save manually: https://gbatemp.net/threads/release-3ds-snes-save-converter.574927/
To answer the question though, you can just press Ctrl+G then type 30 and press enter, should take you to offset 0x30.
There is a method to import saves into SNES Virtual Console, take a look at the first post here: https://gbatemp.net/threads/research-snes-virtual-console-save-files.498334/
I tried this out and it actually worked for me, I only tried Zelda ATM but I'm gonna try other games too.
Just wanted to say I can confirm that both the game files and working key + updates are working.
I'm not sure about if it will cause bricks, just be sure you know what your doing before attempting. Happy gaming!
As far as I know, we have yet to figure out exactly how to port our saves over to the 3DS yet. Likely due to how saves work on the SNES Virtual Console... but that is simply just speculation on my part.
@Xdqwerty, wire is definitely more practical IMO. Hell these days you can charge a laptop over USB, can't charge a laptop wirelessly though. Wireless chargers, even "fast" ones, are only good for slowly charging devices, plus they generate a good amount of heat too
Power banks can be incredible depending on your needs. 1) I have a 100w capable one that can charge my laptop. 2) Same one can also power my soldering iron (though is overkill for it) 3) a BIG power bank I have with an AC outlet on it can power my desktop weed vape during a power outage
