Blu-Play DOOM I Port by Sleirsgoevy, Homebrew Games with C / C++

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.

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.

Download: power-of-bdj-master.zip / Power of BD-J GIT / bdj-cibyl-master.zip / BD-J Cibyl GIT / bdj-doom-master.zip / doom.zip (Compiled) / BD-J DOOM GIT / Doom-BluPlay.iso via Blu-Play.com

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:

• Minimal PS3 BD-J SDK tweaked to be compatible with a PS4
• BD-J on PS4 -- a hack to use more than 6 MB of memory
• Cibyl -- compile C to Java
• DooM I (1993) running on Blu-Play

To quote from sleirsgoevy on the latest update: I finally got myself onto it again, so I publish a new version. Changes from the previous version:

• Background music is finally implemented via (sort of) MIDI player (The quality sucks though, and it eats almost 1MB of Java heap).
• X key now sends both KEY_ENTER and KEY_RSHIFT, to allow running (sadly we're out of keys...)
• Fixed the 1000x0 issue

(Side note on the key shortage: it may be possible, with some effort, to intercept the "Flick Left/Flick Right" events (+-15s on PS4, don't know if these can be easily triggered on other devices) and e.g. remap them to "prev/next weapon" to gain 2 more buttons.) The port can now handle OOM in MUSFile constructor.

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.

Thanks

Some YouTube vids finally available.

Check out that framerate!!!
That's extremely impressive, considering that it's "just" blu-ray.

Added them to the OP now and thanks for the update!
