It has a large delay when I play the Sunplus, even though I have set the delay at -2.0 (A and B). My PC has a worse delay than the real gaming machines. I am using a hand made pad with cable like tasoller. The seller said, theoretically there will be no delay. And I found a file named JudgeTiming.ini. If there is a possibility, I can set a suitable parameter so there will be no delay.
