We've had this for a while now...
Tracks brightness of the screen during play and at the end of emulation generates a PNG that can be used to simulate burn-in effects on other games. The resulting PNG is created such that the least used-areas of the screen are fully white (since burned-in areas are darker, all other areas of the screen must be lightened a touch). The intention is that this PNG can be loaded via an artwork file with a low alpha (e.g, 0.1-0.2 seems to work well) and blended over the entire screen. The PNG files are saved in the snap directory under the gamename/burnin-.png. The default is OFF (-noburnin).
