iBASIC

As the name suggests, this is an AppleSoft BASIC emulator of sorts, restricted to a handful of period Apple 2 games bundled in with it. The free ("lite") version ships with:* Conway's Game of Life,

• Hamurabi,
• the Beginner's Cave of Eamon,
• Tictac, a Tic-Tac-Toe program,
• and in later versions, Lemonade Stand.

Paying customers also get the BASIC mainframe StarTrek, a generically-named "Text Adeventure" game and many more Eamon levels, as well as iPad support and more.
