Hi, I have a Neotron for half a year, never tried till now. Using vgmplay and some vgz files I don't get any audio out of it. Also not using the linout. Is there some software/demo files available which 100% should give some audio?

I checked my neotron physically. When I follow the trace of pin 49, which is responsible for the audio from cartridge to MSX, it goes through some via's and a 100ohm resistor. It ends at a placeholder for a volumebutton. So nothing's going to pin 49.
Try playing a VGM file and use the line-out.

Maybe stating the obvious but make sure the vgm song is for OPNB. Neo Geo games for example

Thanks. Do you have a link to a working OPNB song?

Thanks.
I tried:
a:\vgmplay 01blaz_01.vgz
VGMPlay 1.3 by Grauw
Loading 01BLAZ_01.GZ...
Not a GZIP file.
The file is 601761 bytes big
Could you send me working file(s) to j.taverne@gmail.com?
I will appreciate it!

I got it working by renaming the vgz to vgm. :-)
