Java Homebrew Running On PS4

This should not come as a shock that it actually works, but should be more of a shock that Sony didn’t find some way of blocking this method of running homebrew from being run via a burned disc.

A few days ago zecoxao created this thread requesting that people make some BDJ homebrew, most of us assumed that it should work, but none of us knew 100% if this worked or not, until aries2k posted these two videos:

Here is a quote from the post he made on the forum:

Unfortunately, these emulators would have to be recompiled without using the START or Select buttons since the DS4 doesnt have them. I couldn´t get most roms I tried to start on both emulators. Also no sound yet with BD-J homebrew

There´s more BD-J homebrew than I thought.
Still I don´t think anyone made use of the network and HDD storage capabilites like with BD-Live. I´ve transfered various files from BD-Live over to the ps4s harddrive. Lol, it seems to let you use all the free space on the HDD. I´ve used BD-LIVE on another BD-Player with a usb to see what kind of files are transfered and there are some .jar files in there.
So in theory maybe it would be possible to tranfer BD-J homebrew to the ps3s hdd and then use a BD (boot)disc to select the different homebrew on the HDD through BD-Live?

I have reached out to the developer of the original PS3 Minimal BDJ SDK to see if he could update it, so that it accommodates the PS4 control pad, also Blu Ray Java and Java in general should be more advanced now than it was back on the PS3 and with more power on the PS4, perhaps we could now implement sound and perhaps have better homebrew.

    Here are some facts:

  • This is NOT a hack.
  • This is NOT anything major and will not lead to anything major.
  • This will NOT let you run PS4 “backups”.
  • This will NOT give you any access to the PS4’s OS system files.
  • This is NOT illegal.
  • This does NOT void your warranty.
  • This will NOT let you run PC games on your PS4.
  • This will ONLY let you run Java software.

We all know that this isn’t any type of break through, it is using a system that is already in place, to run something that we have created ourselves, it runs from disc and does not touch any part of the PS4’s operating system, so do not expect anything huge from this.

If anything comes from this and the SDK is updated, do expect some fun homebrew and app’s that we can use on our PS4’s.

This method will also work on the PS3 and should work on the Xbox One, not sure about the Wii U, but we won’t know until it is tested.
