Lesson number 1 - don't make 3 topics with not alot of info within 5 mins.
That aside, to make a passme (passkey) you can have a look at Natrium's site
here. (You can also order one off here, which I did because I would probably cost myself more in burn ointment than its worth.)
Also, to find out what firmware you have (which lets you know if you need a pass me 1 or 2) visit
ndshb.com's reference chart.
Then, go
here (ndshb again) and it will tell you how to use the passme(2) with the M3.
Don't pay attention to anything that is between the OLD METHOD flags, I suppose thats there for referenceAfter all this, when you actually want to download DS Homebrew, there are heaps of sites to look at,
Google is your friend!
