Dennis Intravia (NES Driver)
Dennis Intravia is an unofficial name of the sound driver used by Mind's Eye. It was programmed in 6502 assembly by Dennis Intravia, who also founded and composed music for the company. It is unknown how Dennis wrote music and sound to the driver, but it is thought that he either use a custom MML, or converted MIDI files.
The first and only game to use the driver was Muppet Adventure: Chaos At the Carnival, which was exclusively released in North America. Mind's Eye also developed an NES adaptation of the game show Fun House, but it was unreleased, and instead handed to Ironwind Software to develop. It is thought that the unreleased version uses Mind's Eye's sound driver.
The driver outputs to the RP2A03 and uses the DPCM channel for drums. It uses a digitized snare, tom, and open hi-hat for the DPCM. It is also one of the very few NES drivers that doesn't make use of the noise channel for music.
