还有很长的路要走

目前列车的动态lcd屏幕还是没有适配，一些列车模组的兼容性还是比较差

Don’t buy.

This game, no matter what, crashes. Even when I set every graphics setting to the lowest, it never loads up any route. Reloaded and tried again millions of times, same result. Stuck on the menu eternally. If I could give 0 stars I would, there’s nothing here. It IS a scam

This app is essentially the gateway to open BVE for mobile, thanks for the new legacy update. Highly recommend ultra high-quality graphics..
