Piyotama

 is a puzzle game developed by SCE Japan Studio and published by Sony Computer Entertainment on June 22, 2007 in Japan, on August 9, 2007 in North America and on December 14, 2007 in Europe for the Sony PSP and Sony Playstation 3. The game featured 4 skin packs, but with the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The PS Vita release of the PSP version allows to download all of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details). Also, each DLC was distributed only in some regions which varies for each DLC. Some were released in North American regions as an update rather than a proper DLC download.

How to obtain
The DLCs can still be obtained on the PS Vita release from the Playstation Store or, on the PSP, by purchasing the PSP version on a Playstation 3 system and then transferring them on the handheld console.
