Developer DAVEX has added two snazzy features to Mr. Mirakichi’s Gameboy & Gameboy Color emulator for the PSP…

1. Rewind.
2. Mirror mode.

Quoted from the readme, because I couldn’t explain it any better…

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. By default, it’s mapped to “RTRIGGER” button, but you can configure it in “KEY CONFIG” menu.

In mirror mode, like it’s name says, all graphics are horizontally inverted. So, if your favorite gameboy 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.

I totally dig the “sands of time” feature, man that’s cool! Great job DAVEX.
