no edit summary
Flipnote Studio uses 3 different file extensions:
*[[Flipnote Files\PPM|.PPM]] - these are the animation files themselves
*[[Flipnote Files\LST|.LST]] - This is a list of the files in the current directory
*[[Flipnote Files\PLS|.PLS]] - These are the sticker files, and the recently edited file.
*3 hex bytes, the first byte's high nibble is not the same as the first byte of the file name
*First location: D3 5B 20 30 39 30 39 38 34 31 43 44 42 45 42 31 00 00
