Rainbow was one of the first emulators available for Macintosh. Despite this, it has fairly good compatibility with original software. The macOS version adds an improved GUI and significantly improved sound to the original version.
This software can be used with Emulator Enhancer, a shareware add-on that includes:
- Support for USB joysticks and gamepads.
- Support for full screen mode.
- Support for audio effects.
- Support for opening recent games quickly.
- Much much more.
