A port for the PSP called Tales of Phantasia ~ Full Voice Edition was released in Japan in September 2006 developed by Mineloader Software. This version of the game is largely based upon the PS1 release, and contains completely redone voice acting which are now used for most story events. The port also features new battle sprites for the main characters that are more on par with those of later games in the series, such as Tales of Eternia. The PSP port also includes a grade system, also from later games of the series. However, it is unlikely that the PSP version will debut in the US. This is because of the fact that the English version of Phantasia has been licensed to Nintendo, making it difficult for Namco or Sony to release the game on the PSP without much negotiations.
