v1.2.0

New features/fixes

Sound Blaster 2.0 emulation:

The AdLib mode (pg-adlib.uf2) has been replaced with a new Sound Blaster 2.0 mode (pg-sb.uf2)! Code to emulate the Sound Blaster DSP was contributed by Kevin Moonlight - huge thanks to him.

• Sound Blaster 2.0 DSP support is pretty well tested but you may run into issues. Please consult the Compatibility List for titles with known issues, and feel free to file an issue on GitHub to report any problems.
• AdLib/OPL2 emulation has been improved, fixing issues with missing/wrong notes.
• The SB base port can be set with pgusinit with the /p option, and the OPL/AdLib base port with the new /o option.
• Some older titles supporting AdLib are "speed sensitive" and have weird playback on fast systems (even with a genuine OPL2/OPL3). A new /w option in pgusinit can work around these issues in most circumstances.

MPU-401 emulation:

• Fixes an issue reported by zuldan on Vogons where running pgusinit in MPU-401 mode wouldn't work on certain systems. Fixed by initing the MPU-401 and sending the reset MIDI data asynchronously, preventing IOCHRDY from being held low for too long.
• Sysex delay handled without busy wait. Shouldn't have much effect presently, but may allow MPU-401 to be emulated simultaneously with other modes in the future.

General:

• Allows the volume of the wavetable header to be set with the /v option in pgusinit in all modes. This is useful if you want to use the wavetable header to mix in other external audio sources like a CD-ROM drive (connection guide coming to the Wiki).
