After setting the game background to be turned off, it does not take effect in version 1.04.

I found a solution. The user needs to change the game version number to 1.02. Fortunately, I saved a patch with version 1.02 before, and it can be used, but it is not genuine. The game may crash frequently during loading after installation, and the user needs to change several ring arenas and try again. If you want to download and install, please be careful to back up your current game archive. After you install the 1.02 version number patch, your game archive will be deleted. In version 1.02, users can use the Alpha Mask function to change the game background to black, hide referees and other functions.

我发现了解决办法。需要用户把游戏版本号变更为1.02。幸运的是，我之前保存了1.02版本号的补丁，它可以使用，但它不是正版的，安装后游戏加载中可能会经常崩溃，需要用户更换几个擂台竞技场重试。如果您要下载安装，请注意备份您现在的游戏存档，您在安装1.02版本号的补丁后，会删除您的游戏存档。在1.02版本中，用户可以使用 Alpha Mask功能来将游戏背景改为黑色，隐藏裁判等功能。
