Homebrew developer davex dropped by QJ.NET PSP Development Forum and happily announced that the owner of Sega Game Master PSP emulator, Mr Akop (aka uberjack), has finally allowed him to tinker with the program's code and add Rewind and Mirror functions (RM).

You've probably heard or even tried this very same functionality in NesterJ. But for the uninitiated, the Rewind function allows users to warp back in time (within the game, of course) without thinking about saving states.

The mirror functions, on the other hand, "mirrors the look of the game so a left-to right side scroller is now played in reverse. This is really a nifty addition to SMS Plus which was just upgraded to v1.2.3 just a couple of weeks ago.

Before installing this program to your PlayStation Portable units, kindly go over the Readme.txt file included in the download for more information and key mapping to trigger RM.
