This weekend PlayStation homebrew developer bigboss (aka psxdev) made available a Prospero App0 List and also shared via Twitter a Prospero BD-JB Reimplementation based on the PS4 BD-JB / PS5 BD-JB presentation (PDF Report) from TheFloW at HardWear 2022 and @sleirsgoevy's BD-JB Base Code alongside a PS4 9.03 / 9.04 Ret.bin Payload Test via @zecoxao on Twitter for those with a BD-JB Blu-ray (Pong / Doom / Blu-Play.com) that returns nothing except the text 'Hello World' after a black screen. :geek:

I wonder if a small Java File Browser can be created and files pulled from a USB.. still early days but a lot has happened since this BD-JB has come about.

It should work on 4.51 and below. But we are not developers, we need to be patient and do not update our consoles. let the Masters do their job, soon we will find out.
