Hello!

Since a while ago, the chip emulator code is being used around the world out of DosBox, often in various music players, games, bank editors, libraries, etc. It has a GPLv2+ license which means, any project that uses it (even its library), also should use the GPLv2+ license.

I do have two of my projects that use your OPL3 emulator (https://github.com/Wohlstand/libADLMIDI and https://github.com/Wohlstand/OPL3BankEditor). For the libADLMIDI I keep the long-term plan to switch license into at least LGPL because there are some projects that want to use my libADLMIDI library (such as DXX Rebirth), however, they have a GPL-incompatible license (left by the author of the original code) which makes no way to legally link my library to it. Speaking about chip emulators, I use many different emulators (they are different by performance and accuracy level, and they all have LGPL 2.1 license except for Opal (public domain) and DosBox OPL3 (GPLv2+)), and the DosBox OPL3 is the best one for low-end hardware (it's almost accurate and gives the fastest performance, which I measured with my own benchmark at my OPL3 Bank Editor), and I want to keep using it.

And therefore, I have the request (if possible) to switch the license of the dbopl.cpp and dbopl.h emulator's code into LGPLv2.1+.

Is that ever possible?
