I will still use KWX’s engine for rendering the courses, but I came across this YT video that explains a mode 7 - style 3d coded into C++, and I made an Arcade project based on that video and it runs really well!
It won’t do much on hardware as it isn’t optimized for hardware like KWX’s engine (and it doesn’t have sprites/objects), but it runs great on the simulator!
It even can have a top easily!
I just did this for fun, as a proof-of-concept!
