Oop missed that. I do recall in Windows 98 the calibration was much more temperamental on the 15 pin game port controllers compared to Windows XP. If the OP's PC is a much older motherboard, CH put out an ISA gamecard with twin 15 pin joyports that has speed control capability to tailor it closer to the older mother board clock speed. Sometimes this would help in the calibration, but only for much older ISA slot PCs.
