If I missed the right topic, I apologize.
I use the MSX SX-1 emulator (8bit4ever SX-1) and the MSX-Blaster OPL4 - 2MB sound card (https://www.8bits4ever.net/product-page/msx-blaster-opl4).
I'm having trouble running any demos on this set.

Is there anyone who uses the same system and can confirm functionality or malfunction on SX1?
Most demos end with the message OK and nothing happens.

For example, I don't work:
https://www.generation-msx.nl/software/compjoetania/jungle-s...
https://www.generation-msx.nl/software/result?q=pure
https://www.generation-msx.nl/software/result?q=homepop
https://www.generation-msx.nl/software/infinite/coral-2/rele...

However, some demos work without a problem, so there will be no hardware failure.
For example it works: https://www.generation-msx.nl/search/result?q=Dutch%20MoonSo...

If it tests them at https://www.file-hunter.com/ all the demos work there, does anyone know where the problem is?

In SX-1 I use floppy disk images (DSK) and SofaRun program.
Thank you for the advice.

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.

Thanks for the advice, and is it possible to get advice somewhere on how to set up SofaRun?
What exactly is the GR8NET?
I use the standard SofaRun settings.
I'm still new to MSX, so maybe I'm asking stupidly.

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

I was checking the coral2 demo (the other ones I do not have myself).

Using sofarun I was not able to get it to work. It shows the infinite logo but then fails with an error in basic.

Using the GR8NET it does work. I guess sofarun does not support it somehow.

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

Try any of these: https://www.pouet.net/groups.php?which=7341

If you extract files (not dsk) to the SD card you can start using the COM file. For Coral 2 you can use CORAL2.BAT.

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 think sofarun emulates disk files within the MSX system and therefore can be overwritten by any application that you might run. MSX does not have memory management, so there is no way to protect the disk emulation.

There is also disk emulation from Nextor but I never tried it:

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.
