A simple raycaster demo for the Sony PSP.
This code is not optimized - it runs really slow. There are a lot of points that could be improved, but this is just a proof of concept.
The textures are from Wolf3D, by id software.
Clone the pspdev repository and run the steps on its Up and running section. Having done that, you should have a PSP build toolchain ready to use.
Then, simply clone this repository and run make on its root directory, and you should end up with an EBOOT.PBP file, which can be used to run on an emulator like PPSSPP, or in the real hardware.
