FAQ

Does NXPress download games or keys?

No. It contains no keys, no games and no copyrighted content, and it never downloads them. It goes on the internet only to ask GitHub whether a new version is out, and that can be turned off in Settings.

Are the files it writes normal NSZ files?

Yes: the same format nsz writes. DBI, Tinfoil, Awoo, CyberFoil and Sphaira install them; see Compatibility. The only exception is the experimental extra compression, off by default: the files that use it are decompressed with NXPress before installing them.

Can it damage my games?

Every new file is decompressed again and compared with the original before it gets its name. The original is deleted only when you ask for it and the new file passed the whole check. See how every file is checked.

Which level should I use?

18, the default, unless you are in a hurry. Compare the levels on this computer tells the size and the time of each one with your own games.

Solid or in blocks?

Solid to install with DBI, Tinfoil or Awoo. In blocks when an emulator that reads NSZ will use it too.

Why is a game marked Skipped?

It has nothing to compress, and its row says why. The most common case is a game in sparse storage: it installs as it is, and only the experimental extra compression compresses it.

Does it replace nsz?

In scripts, yes: it takes its options and writes its format. It also has a window, Combine by game, Trim, FAT32, Rename and Verify against a DAT.

Does it need anything else installed?

No: it is one program, with no Python. On Linux the window needs GTK 3 and WebKitGTK 4.1, which most desktops have.

How do I carry NXPress on a USB stick?

With the portable download for Windows, or with a folder named settings next to the program. See Installation › Portable.

How do I update an optimized game?

With the new update and the original game: optimize them again together and install the result. Do not install the official update over the optimized game.
