With braindump, i have a copy of romfs.bin on my computer, after with extract_romfs.bat , a romfs folder appear. But, the only problem is how to extract the dt and las file SSB3DS ?

I have Python 2.7, and the smash-stuff file on the romfs folder of SSB.

What is the command to extracting the two files ?
