New 'NoPayStation' option in the Store tab lists PSP_GAMES.tsv and PSX_GAMES.tsv, downloads each item's encrypted .pkg and decrypts/extracts it with pkg2zip into a configurable output dir (<dir>/PSP/<TITLE_ID>/ and <dir>/PSX/<TITLE_ID>/). Downloaded PSP games and PS1 Classics appear in the Library (games/eboot and ps1/eboot respectively) and copy to the PSP as PSP/GAME folders. - app/nopaystation.py: TSV fetch/parse (cached) + pkg2zip discovery/extract. - app/transfers.py: NoPayStationSource (scan + download). - Settings: NPS output dir + pkg2zip path (QSettings nps_dir/pkg2zip_path). - StorePage: NPS source + content-type combo (PSP Games / PS1 Classics), per-item cover system, TSV release dates, nps-download job kind. - Library: _nps_library_items ingest, on-PSP detection, folder copy/delete, PPSSPP play disabled for encrypted PSP EBOOTs. - README: document the source, pkg2zip + npdrm_free requirements.
