Look inside the Devices Manager for LPT.
It pretty sure use entirely different address.
It may only support legacy printers.

yea I did there is an option to set "legacy Port support" but it doesn't work.
I can't set the port manually.

Just wasted an entire friday getting my OPL3LPT to work on windows 10 using a LPT PCIe card with asix chipset.
tried many configuration including its legacy port support but Scummvm couldn't open port 278,378 or 3bc

Vincent Bernat implemented OPLxLPT support in ScummVM through use of the libieee1284 parallel port library. This library usually does a good job in terms of hardware abstraction, and only falls back to the legacy PC I/O ports that you listed if there is no other way to detect the I/O addresses of the parallel ports in the host OS. Or at least that's how the library works on UNIX-like (POSIX) operating systems. See his merge and the accompanying discussion here: https://github.com/scummvm/scummvm/pull/1137

So you might want to try this in Linux for better results. Alternatively, you could ask the libieee1284 developers to improve Windows support, or make such an improvement yourself and create a pull request for it, if you have the skills and time for it.

I neither have skills nor time, but I can try this on Linux.

Well some cards can be forced to legacy ports you can try select resources in device manager (if possible)

Like I said there is a setting to enable legacy port support but you can’t select the port.
And by Ressources you mean the i/o area? I can’t see how to change that

hi Dreamblaster

the opl3 arrived today and i was eagerly trying it out (using the tsr on my dx2-66 laptop). but i need some advice - neither Doom2 or Duke3d plays any music (both setup using adlib). would these require exe-patching or should the tsr be enough? i have no issues when playing the opl test music

Hi
yes, for games using protected mode, it needs patching.
Adpatch should do the job for duke nukem 3d and doom II : https://github.com/pdewacht/adlipt/releases
Have a look at the demo pack too ? The Unofficial OPL2LPT and OPL3LPT demopack (for convienient testing of Adpatch)

😀 Thanks.

Duke3D now works perfectly.

(not lucky yet with Doom2 or Doom as they hang on the "initializing...." bit)

Can you try the doom from the demo pack first ?

No sound from OPL3TEST on a Winbook FX. Is this one of those systems that it won't be happy on?

My OPL3LPT has the 1k pull up resister soldered into it.

Does an OPL3LPT work on the LPT-port of a zipdrive? if so, what version is the better one OPL2LPT or OPL3LPT ? thx!

seems so, I switched it from my euro-pc to my tandy 1000 and the democheck worked great.

Completing a new revision of opl3lpt : OPL3LPT V2

- soundchip showoff at bottom side

Great !

What are the benefits of the new Revision ?

- producable again !
- showoff of sound chips at bottom side, also easier to replace these
- should be compatible with existing 3d printed opl3lpt cover (but maybe a new will be designed)

Very much looking forward to grabbing one when they exist again. Is there some kind of timeline for production at this point, or is it "sometime in the future?"

well i made a few prototypes and they worked well, i sold these
next up is making a larger batch
i think in about 1-2 months i will have more

Sweet. Yeah, sign me up!

Anybody interested in compiling Windows 3. X driver? Just asking, There is resources with non usual lpt address though, So I think it has to be redirect to 378, but in bin file there is wrong address. I can't make this file, can somebody please?
