Microsoft Adventure

Microsoft Adventure was programmed on a mainframe computer in fortran language. Later it was ported to run on the IBM PC. This was the first game ever released for the IBM PC. The whole game was translated to assembly language because this was the only way to make the game fit to the limited resources of the early IBM PCs. Specific mainframe aspects such as time sharing were removed. It was made into a booter game because this was the only way to get enough resources of the IBM PC by bypassing the booting of MS-DOS into memory.

This game was technically not a MS-DOS game but a PC booter game, like many of the first games for IBM PCs. A small operating system on the floppy disk booted the PC and launched the game without the need for MS-DOS.

It had a backup feature for making a backup floppy, but only ONE. After executing, the original was modified so no backups could be made anymore.
