Makewav converts ROM images for the Atari 2600 into .wav files that can be transfered into a Cuttle Cart or Supercharger for play on an original Atari 2600.

For the Supercharger: It can convert Supercharger ROM images (6k, 8448 bytes and 32k) into .wav files for use with the Supercharger. It can also convert 2k and 4k ROM images that were never intended to be played on the Supercharger. The 2k and 4k images may not work with an unmodified Supercharger.

For the Cuttle Cart: It can convert almost every ROM image ever made for the Atari 2600 (the single known exception being Pitfall II) into .wav files for use with the Cuttle Cart.
