Just use Panasonic SD Formatter v3.1 and report back exactly what happened when you tried to format USING THE PROGRAM'S DEFAULT OPTIONS (don't touch anything except the 'format' and 'ok' buttons)
First, add all the EOS v1.13 files from here
http://down.supercar...12_0323_eng.zip
THEN you overwrite the files in the _dstwo folder's files (I'm referring to the _dstwo folder that's on your micro sd card now, because it's part of the EOS v1.13 files) using the files inside of the _dstwo folder available here in this next download (only the stuff inside that folder called _dstwo...nothing else)
http://down.supercar...12_0323_eng.zip Your computer will ask if it's ok to overwrite the files inside the _dstwo folder on your micro sd card and you say 'yes'. You have done this step to make your card compatible for the newest DSi firmware. Remember how to do it because if Nintendo makes a v1.45 firmware then you will do the exact same thing again. Finally, put the ds2boot.dat file on the root of your micro sd card
Then you add the file inside of the archive from this download, to the root of your micro sd card
http://down.supercar...e_v1.16_eng.zip Now, using your DS Lite/DS (whatever DS, just as long as it's not a 3DS v4.2.0-9 console). This step requires more than adding the file though. You need to run the dstwoupdate.dat file as if it were a game. This step, when used in conjunction with the others, will make your SCDS2 compatible with the latest 3DS firmware v4.2.0-9.
Keep in mind to never ever interupt the update process as it will ruin your SCDS2, or any flashcard. Wait until the process is over and says it was successful, and then power cycle your DS. In the case of the SCDS2, you should remove the micro sd card and delete the ds2boot.dat and dstwoupdate.dat file, after turning off your DS, and
before turning it back on to see if the update really was successful.
Voila you're done.
