RSF generation - /rsfgen

• rsfgen.py - Generates a .rsf, using a .3ds/.cci, decrypted ExHeader, and a template RSF (original source)
• rsfgen_cia.py - Modified rsfgen, generates a .rsf, using a decrypted CIA and a template RSF
• rsfgen_exh.py - Modified rsfgen, generates a .rsf only using decrypted ExHeader and a template RSF; does not automatically get CompanyCode, ProductCode, or UniqueId
• dummy.rsf - Template RSF for use with rsfgen; must have DOS line endings (CR LF, try unix2dos if your generated rsf looks strange) (original source)
• dummy.rsf.zip - Archived-form of dummy.rsf, as an easy way to download this file with the proper line endings

Downloading - /downloading

• TitleDownloader.py - download update files from Nintendo CDN; requires make_cdn_cia in the user's PATH (original source)

Seed database - /seeddb

• seeddb.bin - contains seeds for games using seed crypto introduced in 9.6.0-24
• List of games and title IDs that use seed crypto
