If you enjoy using old-school interface programs then you'll definitely get a kick out of this new homebrew DOS emulator developed by Darksidious for the Sony PlayStation Portable. Entitled PspDos 0.1, this Lua-based program features some of the basic commands found on the DOS platform, as well as some additional commands applicable for the PSP handheld.

The interface itself is a literal blast from the past, complete with the basic DOS prompt set on the root directory of your handheld's memory stick. PspDos also includes a set of commands which allows you to manipulate some files and directory found on your PSP.
