Sony has released a number of previously released PlayStation video games, remastered in high-definition (HD) for their newer consoles, a form of porting. A number of related programs exist, the most prominent two being "Classics HD" (also known as "HD Collection") and "PSP Remasters". The former consists of multiple PlayStation 2 games compiled on one Blu-ray Disc. The latter are individual PlayStation Portable games republished on Blu-ray. These games are not direct ports, but remastered versions in high-definition, to take advantage of the newer consoles' capabilities. The remastering of the games include updated graphics, new textures, and Trophy support, and some of the remastered games released on PlayStation 3 have included 3D and PlayStation Move support. Some HD remasters have also been released individually or in bundles as downloads on the PlayStation Store; others are released exclusively as downloads.
This remastering began in 2009 with the release of God of War Collection; it originally started as only PlayStation 2 (PS2) games being remastered for PlayStation 3 (PS3). PlayStation Portable (PSP) games began being remastered for the latter in 2011; Monster Hunter Portable 3rd HD ver. was the first of these. After the release of the PlayStation Vita in 2012, several of the remastered PS2 and PSP games began being released for this platform. Some original PlayStation (PS1) games also began being remastered. With the launch of the PlayStation 4 (PS4) in 2013, Vita and PS3 games, in addition to the older platforms' games, began being remastered for it. Developers have also remastered games that were not originally released on a PlayStation console and remastered them for PlayStation platforms, in addition to releasing them for other non-PlayStation platforms.
