Following the second PS4 Blu-Play homebrew release The UFO Game! from LuBlu Entertainment, developer sleirsgoevy demonstrates that you can create Blu-ray Disc Java homebrew with C or C++ using Cybil MIPS transpiler. Simply convert your C / C++ code into BD-J. šŸ„

Sounds too good to be true? I thought so too, but then he dishes up a working Blu-Play port of Doom, after just a couple of days.

I tested it on PS3, and found the framerate surprisingly good. It's currently still just an early preview of course, but it's definitely a good proof of concept.

Would be interesting if any homebrew devs could try porting some of their native homebrew to PS4 BD-J using this approach. Here are some related topics on PlayStationHaX for those interested:

There are many limitations with BD-J in regards of speed, API's, input controls, etc etc. There's no SDL or OpenGL or any 3D API. You're working with Java 1.3 from 2003.

But as we can clearly see, that doesn't mean you can't do anything with it. :)

I don't know how much speed a Gamecube emulator would need, but after seeing the framerate of this Doom thingy, I say why not.
