The PSP Scene began slowly with only a few groups with the knowledge of dumping the UMDs, then the scene grew as tools for dumping were released. Now, the PSP Scene is growing quickly with much potential since it is easy to dump UMDs.

The scene started as a joke by release group Kalisto on April 1, 2005, releasing a fake Metal Gear Acid and then only ten days later was the PSP version of Metrowerks CodeWarrior leaked. On the 4th of May, 2005, Paradox released three games, these games were pure ISO dumps and thus the scene began. Several joke groups appeared with names like Dynarox and NONEEDPDX releasing several games.

When Paradox's dumper utility was officially released to the scene in early June 2005, there was a constant stream of at least five new releases every day for two weeks, coming from dozens of new groups. Before even the PSP was released in Europe, European versions of games were being released and when it was officially released in Europe, a huge influx of new dumps appeared and even more groups participated.

Today most of the original groups from the earlier days of the scene are gone, only a few remain and the ones that do have dumped dozens of games. New groups still appear but since the beginning, the scene has slowed down a lot.

On May 19, 2006, Paradox returned to the PSP scene to release a +9 trainer just to prove that trainers for Sony's handheld is possible. Since then, no other group or person has publicly released any trainers.

Some of the prolific and notable groups in the PSP scene are: ARTiSAN, Caravan, DMU, Paradox, PGS, PSP-Dev, Psyfer and Start2.

Other PSP ScenesEdit

The PSP Scene is often used by other communities to label themselves. Sony's unsuccessful line of UMD media such as UMD Movies and Audio have been merged into a separate scene, allowing people to dump their movie or audio UMDs and release it. The UMD Media Scene started off with the original PSP Games Scene, but has since branched off.

The PSPs massive home-brew capabilities has created its own community-based scene, although this is not really a scene, many home-brew developers label themselves as part of the scene but only a few notable developers such as BOOSTER or Humma Kavula have been given praise for their popular programs and even adopted into the scene.

Takka's famous unofficial Japanese version of gPSP, which has a greater amount of features.

Unfortunately, he does not credit Exophase and goes his merry way violating the attribution clause of the GPL. Otherwise, he does release source code (now lost...) and makes a pretty good program.

Apparently takka himself quit after 2011, disowning gPSP-kai after 2011 and apologizing for the issues he caused. No reason was given.

  • UO gPSP-kai and gPSP-J - Unofficial versions of gPSP, which have been controversial since their inception. At least the source code is made available.


Strongly related to takka in some manner.

  • CP1PSP
  • CP2PSP




Effort should be made to finally bring together Takka's and Exophase's code into one unified gPSP, which can then be pushed downstream.
