I have DOS_Box installed on MacOSX and have Forgotten Realms Unlimited Adventures (FRUA) installed. It allows you to make and run your own, or other people's game modules that are just like the Sierra Gold Box D&D games, like Pools of Radiance, Curse of the Azure Bonds, etc.
There is still a small group of people that make and publish modules for FRUA and it has a mailing list and forum site. Too bad FRUA was never ported to the Amiga 68k.
