Today i wrote program that can help to detect OPL3 clone. This program plays simple 440hz sound. It sounds like simple sine wave on OPL3 and like FM sound on clones. This program relies on hardware bug that presents in the real OPL3 core. I've tested it on YMF718 and various emulators.
Report your results here. I'll add them to this list.
