IBMulator 0.5

Windows 3.1

Windows 3.1

In this version:

  • Joystick emulation
  • Custom HDD type
  • ROM load from bin files and directories
  • Lots of bug fixes

With the custom HDD type (45) you can use a drive with 1024 cylinders, 16 heads, and 62 sectors per track, for a maximum of 496MiB. Theoretically the maximum value for sectors per track would be 63, but a bug in the BIOS prevents the system to correctly format the drive.

Among the bug fixes: Windows 3.1 and MS-DOS 6 now work.

The Windows version has been tested only under Windows 8.1 and the Linux version under Ubuntu 14.04

The configuration file (ibmulator.ini) has changed. Delete the old one to recreate.
