I don't have any experience with this format so can't help out there, but if you can find someone who knows the format that will be a start. If you can further convince them to write some code so that they are playable in AdPlug then I will be happy to merge the code into the project. You may find it is indeed the same issue as #6 - without knowing more about the file formats it's difficult to say for sure.

May not actually be .adl. I noticed that there seems to be some prior work in the (abandoned?) Free In The Dark project that could be helpful, this for instance looks very promising: https://github.com/somaen/fitd-residualvm/blob/master/src/music.cpp

I'm not holding my breath on finding anyone to look into it, though.

@somaen @klusark Hello!

Can I reuse your music player code from Free in the Dark project in the AdPlug project?

The music.cpp/.h is licensed under GPL v2, but the AdPlug project is LGPL v2.1.

@binarymaster Neither of us wrote that code originally. The original authors are listed in https://github.com/somaen/fitd-residualvm/blob/master/AUTHORS. Hopefully you can get a hold of them.

Alright, I'll try to contact them.

@binarymaster Any news in adding ADLM code to AdPlug? Authors didnt answered?

I sent a mail to Vincent Hamm at Feb 28th, still no answer.

Could you try to contact him on LinkedIn?

Someone on the #scummvm irc channel promised to pass a word of this bug and the desire of his input to him a couple of months ago, but also cautioned that the likelihood that he reacts to it in any way is slim. Clearly he hasn't.
