A few years back we saw some
PS4 BD-J Homebrew ports followed more recently by
PS4 Webkit Emulators, a
BDLive Bug and a
PS4 JavaScript Emulator demonstration video with some answers to common questions recently by musician and coder
Mr_lou.
To quote: Hello all. Just signed up here, and thought I'd introduce myself (in this thread because BD-J dev is the main reason I signed up, and I don't actually own any PlayStations).
Been working on a BD-J project for 5 years now. Info at

Is anyone here still interested in BD-J? I think I can answer a few questions from this thread (although it's old), so here goes:

Would make more sense if the PS4 supported such a thing from a USB stick or similar... Wasting a blueray disc for a java app? No ty... o.o
Yea, Sony blocked the possibility of booting a Blu-ray Disc from USB, as we all know. But I believe it's still possible to run BD-J stuff from a USB - if you boot from a disc.
So yea, you will still need to burn a disc - but you can settle for having this one disc for booting, and then run whatever Xlets you have on your USB.
I admit I haven't tried this myself yet (because I'm using a Dune HD Smart D1 for testing which lets me run my stuff from harddisk), but from what I've read in HDCookBook it should be possible, because:
- Xlets can start other Xlets
- The disc filesystem gets merged with the USB filesystem (for BD-Live).
So, you could (theoretically) "waste" this one boot disc, and then just use USB sticks for...
