Psp was once one of the most fanous things but now ps4 took over it ! before I use to love it.! bcoz it was portable and in early times .it was a rare thing.Apart from playing audio files, the PSP also lets you watch movies and TV series, as long as they are in MP4. Unfortunately, the PSP reads only a handful of video files, since Sony apparently refused to release a pack of codecs for the portable console, so its use is somehow limited. Downloading unofficial codecs on a homebrew page is still a possibility, but installing them takes some time.
