Description:
DAVEX's unofficial version of Ruka's NesterJ NES emulator. Added is mirror mode and the ability to rewind ("sands-of-time" mode...)

"...With rewind (or "sands of time", if you prefer) you can warp back in time without worrying about saving states. If you made a mistake, you can press "rewind" button and undo it...."

"...In mirror mode, like it's name says, all graphics are horizontally inverted. So, if your favorite platform game is played from left to right, this time you can have the choice of playing it from right to left, giving it a little novelty touch..."
