screenshot modes are now divided into single, motion and composite 'single' works well with regular displays (ie. Pitfall etc.) 'motion' works well with some flicker kernels (eg. zookeeper and similar) 'composite' meanwhile is very good at creating images with most flicker effects eliminated (eg. Wenhop) and capturing motion (eg. Wabbit)
