Compatibility of MSX SX-1 and MSX-Blaster OPL4

I got the same setup, works perfectly.

You probably need to figure out the right Sofarun settings. I mostly run from a GR8NET which has the option to emulate the DSK file in the GR8NET. Never tried it without it.

All the software I currently use for the OPL4 is DOS2 based so it works without any tricks or settings. This includes a game I am working on, the NOP Mod Player v2, MBWAV and MBFM, vgmplay etc.

Oh, I already found it, so I don't have this device, I use an installed SD card reader which is directly in the SX-1

You don't have the same configuration. OPL4 from the GR8NET is emulated not that of the MSX-Blaster OPL4.

Thank you, I'm not directly interested in the Coral2 demo, I also have it as files, I'm more interested in testing the demos that I gave in the example.
Alternatively, I can place demos on the Internet so that someone can take the test.

p.s.
The Coral2 demo that I have in the files and not just as a DSK file works for me.

I've been using NEXTOR, I've been trying for several hours to understand how to set or force NEXTOR to work on all DEMOS, but I really don't understand why it doesn't work for me, other programs usually work.
Would anyone be willing to test a malfunctioning DEMOS?
If possible on MSX SX-1 and MSX-Blaster OPL4 - 2MB?
I can privately send a download link because I don't know if these files are free or commercial.

p.s. i read everything about MSX -SX-1 and NEXTOR, but I still don't understand how to set it up, maybe it's a language barrier, English is not my native language, I use google translator and there's a problem to understand everything from translation.

Is there any procedure to set up NEXTOR and SofaRun for the SX-1?

Thank you very much for any advice.
Thank you.
