Créé par Avery Lee (l’auteur de VirtualDub), il s’agit d’un émulateur d’Atari 8 bits (800/800XL/130XE) disponible en 32 et 64 bits. Il dispose de beaucoup d’options ainsi que d’une bonne compatibilité. Il prend en charge les jeux protégés conformément à l’émulation.

 


 
 [changes]

  • Default keyboard shortcuts have changed. Reset in Tools > Keyboard Shortcuts to use the new bindings.
  • Modems now default to handshaking disabled rather than RTS/CTS due to differences in default RTS state for R: devices. Use AT&K0 to disable handshaking and AT&K3 to use RTS/CTS.
