Actually I`ve no idea of anything else and I am not quite sure I correctly understand what your mean under "crossplatform" in this case. Solutions for OSes other than Windows or something? Because it really makes sense if there`s a limited amount of Winamp ports to the likes of Android or iOS or something else and you`re forced to listen to these atypical AIFC files on desktops only.
I`m glad to be of help especially if I coincidentally had to reacquire this specific plugin a week or so ago just not for DoW rips this time around.
