  * artefacts were particularly noticeable in games with flicker kernels

  * composite is very good at capturing motion on the screen
  * activated with CTRL-F12
- other screenshot modes renamed to 'single' and 'motion'
  * activated with F12 and SHIFT-F12 respectively

cartridges

ROM select window
- thumbnailer shows a smoother image
