Introducing MobileBVE, an effort at porting OpenBVE to Mobile Devices. Took some time, hours of bugfixing and multiple headaches, but hey, it works. You might ask, why install this when Hmmsim exists? Well, it's free. And it's more advanced. Well what are the features anyways and how advanced is it? • Direct OpenBVE/BVE Trainsim 2/4 routes/trains support, no conversion needed • Easy route/train importing • Accurate Train Simulation just like OpenBVE or Hmmsim • Proper Scenery Animations • And much much more There's even support Multiplayer play(which OpenBVE nor Hmmsim has), which allows for Online or Local LAN Network Multiplayer Play. More updates to come.
