While I don´t have much time to work on this at the moment, it is nice to see so many people are interested in Shenmue on Oculus Rift. Just in case someone on this forum is interested in helping me out with Shenmue VR, here are some things that I would have to do to make this game VR ready.
-Adjust the field of view (FOV) to 90 - 110 degrees.
-Remove the head from ryo hazuk´s model and place the camera where the head used to be.
-Add free look using mouse movements to null dc. (Similar to how the dolphin emulator does.)
-Enable a shortcut to recenter view in the direction ryo´s body is facing. (So your view does not get stuck.)
-Shrink the UI and menus down so they are in the middle of the screen.
-Add 3D support to the newest version of Null DC. (3D support in directx 9 rendering to be precise.)
The NullDC emulator is open source so it should not be too hard to implement the 3D and so on.
Here is a link to the source code of NullDC
http://code.google.com/p/nulldc/source/browse/While this might be a ton of work this is going to make Shenmue a next gen title.
This is going to allow you to enjoy Shenmue again in a way more immersive way.
The only changes that have to be made to the rom files are the FOV, menus, UI, the model without a head, and placing the camera where Ryo´s head should be. The rest has to be done on the emulator itself.
I hope here are some people interested in porting Shenmue with me to the true next gen of gaming!
