Hello! There is actually progress in that your file actually opened the xgm rom builder (though there was an error message in the cmd window). So I got very excited! But when I try to compile a vgm I get the message "error: an error occured while compiling the vgm". I tried several vgms and also tried to export one to an earlier vgm version (as early as possible, vgm 1.50), but still the same message. Could you compile?
