[1] Initially, downloadable PS1 titles were only available to play on PlayStation Portable (PSP).
An update released in April 2007 enabled playing of these purchased PS1 titles on PlayStation 3 (PS3).
The PS4 and PS5 releases are bundled together, and the former is also playable on PS5 through backwards compatibility.
If a downloadable PS1 game has been purchased for a device released prior to the PS4, the title is automatically added to the user's library on all devices for which there is a release.
Playing PS1 titles on a PSP or PSV does not support local multiplayer that was designed to use multiple controllers,[3] but PSTV supports this feature.
