Introduction:

JOYCALIB, as its name implies, is the best analog joystick calibration utility you can run for your classic PCs with 2-button analog joysticks. It has been tested on a classic IBM PC/XT and an IBM PCjr, but should work properly on any PC or compatible.

WHY USE YET ANOTHER JOYSTICK CALIBRATION UTILITY? Because it's the best, dammit. Check the features:

• User-selectable between all three different polling methods games used (8253 timer-based, tight counting loop, and BIOS function 15,84)
• The default method (timer-based) is not speed-sensitive and can be run on any PC or compatible, from the lowly PCjr all the way up to GHz-speed computers
• Supports both monochrome and color display adapters
• Detects flaky/noisy/"dirty" joysticks and warns the user if one is found
• Full source code is included
