Also, the serial port competes with many other peripherals that could be useful for gaming whereas the LPT is basically redundant and always available.

Also, I previously described a way to connect up to 256 ports to a single LPT.
If you put two 8-bit latches on there, you can use one for address and one for data. A single line on the LPT selects between the two latches you write to.
You now effectively have an 8-bit address bus. With some address decoding logic, you can select between a number of chips/ports on the same device.
This should easily allow to combine an OPL3, CMS, Tandy and MPU401 on the same board.

With all these amazing projects going on, it might be time to revisit your idea. Perhaps in a separate topic/thread?

The Hardware is not the Problem.

The Problem is The Software Stack for this.

Oooh, that SCI0 Ravi General MIDI sound driver is a cool project! Glad I learned about its existence. 😃

It will be fun to try out how these older pre-GM SCI games sound with General MIDI synths, using this driver.

Perhaps someone can also extend or fork them to support General MIDI over RS-232 (including the MPU-232 adapter) without the need for SoftMPU?

To accompany that demo, there's a new release of the S2PTools : https://github.com/pdewacht/s2ptools/releases
The Sierra driver is now based on the latest version of Ravi's original driver, and it has been fixed to work properly on 8086 and 80186 devices.
