Since there is no official ISO, "Undertale PSP" downloads typically refer to homebrew recreations. These are often incomplete demos or "proof of concept" projects rather than the full game.

PortableTale (NobleEpuz): A high-profile recreation for the PSP using the Lua engine. As of late 2025, the project reported roughly 95% completion for the intro and 50% for the overworld, though the battle engine remained unfinished.
