Added delays between register and data writes #2

Closed JudgeBeeb closed 7 years ago

I have tried your library and I get somewhat inconsistent results.

According to the Ad Lib Programming Guide after writing to the register port you must wait 3.3us before sending the data; after writing the data, 23us must elapse before any other YM3812 operation may be performed.

I have added those delays to OPL2.cpp and it seems to work consistently now.

Kind regards

Robert
