Q-emuLator - Sinclair QL emulator for Windows Vista/XP/2000/NT/ME/98/95

This is the support page for the Windows version of Q-emuLator (a Sinclair QL emulator).

Q-emuLator 2.4 for Windows now available!

October 22^nd, 2006. Version 2.4.1 of Q-emuLator for Windows has been released.

Changes since last version:

Use less CPU when not running as the active application.
Debug_68k debugger: SBK command to find the address of a SuperBASIC function or procedure.

Other recently added features:

Partial emulation of Aurora and Q60 video cards.
Compatible with recent versions of SMSQ/E for the Gold Card.
TCP/IP driver: you can now browse the Interned with the QDOS port of Lynx, or use email or FTP.
An integrated QL machine code debugger is now always available by pressing F11 if you install the debug_68k.dll optional component.

Note: High resolution modes need to be enabled in the QL Configuration window (Graphics tab) and are only available full screen. They are available in all versions of Windows except Windows 95 and Windows 2000.
To use the high resolution modes you need to use QL software capable of directly accessing the exteneded video memory, or the version of SMSQ/E for Aurora. QL ROM images like the Sinclair and Minerva ROMs are not able to draw on the extended screen because they lack high-color/high-resolution video drivers (unless a version of SMSQ/E with the GD2 driver is loaded).

Changes for past versions of the emulator are archived here.

To register Q-emuLator, go to the order web page.

Registered users may also want to try "QemuFast", an experimental version of Q-emuLator that runs four times faster.

Warnings:

If you run the emulator on Windows 98 or Windows ME, there may be problems in reading QL floppy disks. These problems do NOT affect Windows Vista, XP, 2000, NT 4 and Windows 95.
Some of Q-emuLator's features are available only in the registered version (full speed and advanced features like more RAM, mouse, TCP/IP, parallel ports, RAM disk, access to QXL.WIN drives and support for subdirectories), or with a temporary registration code.

Q-emuLator requires a QL ROM to work. It works with either Sinclair ROMs (not included, but available on Internet) and Minerva ROMs (version 1.97 included). If your QL has a floppy disk drive, you can also get an image of your QL ROM from it.

The debug_68k.dll optional component provides a simple debugger for the Motorola 68000 processor, always available in the emulator without the need of loading any QL software. To invoke it, press F11 while emulation is running.

Q-emuLator emulates the following QL hardware:

68008 processor
keyboard
display (512x256x4, 256x256x8)
Q40/Q60 video card (512x256x65536, 1024x512x65536, 1024x768x65536)
Aurora video card (512x256x4, 1024x768x4, 512x480x256)
interrupts
file system (access to Windows files, QDOS floppy disks and QXL.WIN files)
sound
serial ports
parallel ports
built-in ram disk
mouse support
joystick

Q-emuLator is shareware

Q-emuLator is a shareware product. You can use the basic version of Q-emuLator for free for personal, non-commercial use. The free version emulates a standard, unexpanded QL (plus access to the Windows file system and QL floppy disks). CPU emulation speed is limited to approximately match the speed of a real QL.
If you like Q-emuLator, you may want to support it by buying a registration code through the order web page.
Registration unlocks many extra features like faster CPU emulation, quick loading of SuperBASIC programs, a more advanced file system supporting subdirectories, access to QXL.WIN files, TCP/IP driver, etc.

The code you get when you register will also be valid for unlocking (automatically, no re-registration needed) future bug fixes and minor improvements (any future releases with version number 2.x).
