NX Game Info uses prod.keys, title.keys and console.keys in the format as defined in https://github.com/garoxas/LibHac/blob/NX_Game_Info/KEYS.md and hac_versionlist.json from tagaya CDN server

• prod.keys: Mandatory keys includes header_key, aes_kek_generation_source, aes_key_generation_source, key_area_key_application_source and master_key_00. Failing to provide these keys will make the application quit master_key_##, key_area_key_application_## and titlekek_## will also be necessary to decrypt titles with higher MasterKey requirement
• title.keys: Optional, but required for Permission check
• console.keys: Optional, but sd_seed key required for Open SD Card feature
• hac_versionlist.json: Optional, but required for Latest Version feature

The application will look for these files at the following locations (other file locations will follow wherever prod.keys file was found)

• Directory of the executable file (.exe) for Windows
• $HOME/.switch e.g. C:\Users\yourname\.switch for Windows or /Users/yourname/.switch for macOS
