That's interesting, where did you get Hoot from and which version then? I can load files by dropping them but there's no sound. This was the explanation from the github guy: "Hoot doesn't play MDX files, it emulates the CPU and sound chips and runs a bit of extracted code from the games."
I got it to work using a player called MXP though, but the sound is very low volume and seems slightly worse quality than in the others as well. I'll check out Foobar2000 but I don't think it lets you mute channels, which MXP does let you.
