Software was distributed for the TI-99/4A in generally three different media:

1. Cartridges called by TI Solid State Software^TM Command Module
2. Floppy disks
3. Cassette tapes.

Some programs even required both a cartridge and a cassette tape or a cartridge with a floppy disk, as the cartridges for the TI-99/4A could not save information beyond what was already pre-programmed onto them.
