The Quest for Undertale on PSP: Fact vs. Fiction Since its release in 2015, Toby Fox's indie masterpiece Undertale has captured hearts across nearly every modern platform. However, for fans of the classic Sony PlayStation Portable (PSP), the search for an "Undertale PSP ISO" remains a complicated journey through unofficial homebrew projects and cautionary tales. Is There an Official Undertale PSP Version?

No, there is no official release of Undertale for the PSP. While the game was officially ported to the PlayStation Vita in August 2017, the aging hardware of the original PSP lacks official support for the GameMaker Studio engine used to build the game. Unofficial Ports and Homebrew Projects

Instead, grab a PSTV, a Vita, or even a Switch Lite. Play the real game. And let the PSP legend of Undertale remain exactly what it is: a beautiful rumor.
