Metro 2033 + Metro last Light 1.0.0

Open your Nintendo Switch emulator, choose File → Load File and pick the downloaded NSP or XCI file. Install prod.keys and the right firmware in the emulator first.

NSZ and XCZ are compressed NSP and XCI files. Decompress them with NSZ Tool, then load them like a normal NSP or XCI.

On a Switch running custom firmware, install NSP files with Tinfoil or DBI Installer. Keep Atmosphere up to date.

If a link does not work, wait a few minutes and try again. If the game will not start, update your emulator and check that its firmware matches the version on the game page.
