UPDATED

1. Downlod the ssr200 tools from fs-tools
2. Download assemble_ssr200.py from various-keitai-assemble
3. Place assemble_ssr200.py in the same folder as nand.bin and nand.oob
4. Use the following commands:

   python3 assemble_ssr200.py nand.bin nand_remapped.bin
   python3 carve_nec_fat.py nand_remapped.bin fat_dir
   python3 convert_fat.py fat_dir converted_fat_dir

Note: If you are extracting data from a P2102V, add the “–disable-normalize” option to the 3rd command

python3 assemble_ssr200.py nand.bin nand_remapped.bin
python3 carve_nec_fat.py nand_remapped.bin fat_dir
python3 convert_fat.py --disable-normalize fat_dir converted_fat_dir

The partitions can now be extracted with TestDisk. Generally, games will be located in Partition 3.
