The machine included IBM drivers bundled on a floppy disk, which enabled properly written software to operate in the machine's RAM and then run on the native Mega Drive hardware. A good example of this shown in the Puzzle Construction program, one of the very few software titles included with the TeraDrive, which included a PC-side editor suite for changing the features of a falling-block puzzle game, then playable on the Mega Drive side. The operating system shipped with the system was IBM's DOS J4.0/V, which was similar to PC DOS.
