The file name seems to be stored in the file header 3 times:
*Original file name 0x0066
*Current file name 0x0078
*Partial file name 0x0092

The file name is stored in 3 parts:
*3 hex bytes, the first byte's high nibble is not the same as the first byte of the file name
*13 bytes for the central part of the file name
*2 bytes for the last part of the file name.

For the file name : G35B20_0909841CDBEB1_002
*First location: D3 5B 20 30 39 30 39 38 34 31 43 44 42 45 42 31 00 00
*Second location: D3 5B 20 30 39 30 39 38 34 31 43 44 42 45 42 31 02 00
*Last location: D3 5B 20 09 09 84 1C DB

The 3 sections of the file name seem to be stored as:
*Last 6 digits of your Flipnote Studio ID
*A random number, possibly generated from a date stamp
*The version number of the file

The preview image is a 64x48 image stored in a 16 colour tile format, with each 8x8 tile taking up 32 bytes of the file.

Here's a photo taken of the altered preview image, reduced to about the correct size.
