Hacking View header of dumped file

[Eddie McArdle]

So I just bought a new 3ds game and dumped it onto the SD card with decrypt9. Now I have the .3ds rom file of it on my desktop, and I'm trying to found out how to get the private header of it.

I tried Gateway rom patcher but it says "nothing found in header" and is just F's. Any tools I could use to grab the header from the rom?

There's an option in decrypt9 to dump the private header itself - do that.

This way you don't have to dump the whole game.

Ah damn I'm blind I'll go back and check! And what file do I end up with then at the end? Is it a text file with my header or...?

You'll get an 80 byte bin file

Nice one got the .bin file! Now I'm pretty stupid with this so bear with me please

I'm looking to get the header (just the 32 letters/digits or whatever) as I'm doing the simple method of putting it into the sky 3ds config file (v.112) if you know which method I mean?

How do I get the header from the bin file?

I've never used sky3ds, but if you just want the first 32 bytes, you can open the file in a hex editor (e.g. HxD) and copy and paste the first two rows.

Ah yes I didn't think! Got the header on HxD! Man you're a legend, can't thank you enough!!
