PSP, short for PlayStation Portable, is a handheld gaming console that was manufactured by Sony Computer Entertainment. It is the first handheld console to use optical media, specifically UMD (Universal Media Disc). While UMDs were the primary storage medium for PSP games, it is also possible to play games from an SD card. This allows users to expand their game library without having to purchase additional UMDs.
There are a few benefits to putting games on an SD card. First, it is more affordable than buying UMDs. Second, SD cards are more portable than UMDs, so you can easily take your games with you wherever you go. Third, SD cards can store more games than UMDs, so you can have a larger game library at your disposal.
