   * The game process will freeze whenever the BGM ends and/or starts, e.g. at certain events that require map refreshing (like going up/downstairs / using the orb of flying / warp staff / wing to fly up/down). / 每当 BGM 播放结束和开始时（例如需要刷新地图的事件：上下楼、使用飞行权杖、瞬移之翼、升华之翼、降临之翼）游戏进程都会卡住。
 * To better the gaming experience, tswBGM is developed to replace the built-in BGM function. In addition, in tswBGM, the original MIDI BGMs were played and recorded using [Timidity++](http://timidity.sourceforge.net/) and [OmegaGMGS2 sound font](http://www.mediafire.com/file/2as606szvw1pbw8/OmegaGMGS2.sf2/file), which makes the music sound more catchy than the Windows built-in MIDI timbre. / 为提升游戏体验，tswBGM 旨在替代游戏自带的 BGM 功能。此外，tswBGM 中使用了 [Timidity++](http://timidity.sourceforge.net/) and [OmegaGMGS2 音色字体](http://www.mediafire.com/file/2as606szvw1pbw8/OmegaGMGS2.sf2/file) 重新录制了原有的 MIDI 音乐，使其听上去比 Windows 自带的 MIDI 音色更带感。
