Q: Are there any new games in the 400-in-1 NES ROM collection? A: Some versions of the collection may include recently discovered or unreleased NES games.

Most "400-in-1" requests involve the or similar "NES-on-a-chip" (NOAC) consoles. These devices come with the games pre-installed on internal memory, but a "ROM download" version is often sought for use on PCs or more advanced handhelds.
