1) Download DiskExplorer (editdisk). You need it to open and edit .hdi files;
2) Open the game with it, use the default profile when asked;
3) Go to Angel folder;
4) Use File - Extract on SYOJO.BAT;
5) Detele SYOJO.BAT from the rom;
5) Open the exported file in notepad, delete everything and replace it with this:
pmd86
m cmd00.scb gdata.lib
6) Save the file and use File - Import to put the edited file back into the rom;
Done!

找到办法了，转一个国外老哥的方法

然后文件内附带的dosbox也有问题，建议你自己去下一个dosbox-x然后把压缩包里的替换掉
我参考这个方法修复了，有音乐。
下载的“Disk Explorer 1.69E”英文版本（vetusware下的），用该工具打开游戏的HDI文件，在angel文件夹里面找到 SYOJO.BAT，把这个文件复制出来后用文本编辑器打开、删除里面所有文本，改为如下并且保存：
pmd86
m cmd00.scb gdata.lib
再把这个修改后的SYOJO.BAT覆盖原文件，重新进入游戏就能听到音乐了
非常感谢
