cartridges and implemented the IntelliVoice expansion and
the Entertainment Computer System expansion as passthru
devices. The official syntax to launch games requiring the
speech expansion is now
mess intv -cart voice -cart2 gamename
which corresponds to mounting the IntelliVoice and plugging
the game cart in its subslot. The official syntax to launch games
requiring the ECS expansion is now instead
mess intv -cart ecs -cart2 gamename
and
mess intv -cart ecs -cart2 voice -cart3 gamename
if the game requires both expansions at once. For additional user
friendliness, we also offer intvecs (which emulates an Intellivision
unit with both expansions added) and intvoice (which emulates
an Intellivision with Intellivoice expansion added) drivers, where
games can simply be mounted with the -cart media switch. [Fabio
