Great news! what can one expect what advantages does 10.1 have over 9.00 is it going to be stable

2023 will be a great year for the PlayStation scene, I can feel it in my bones, maybe even a public HV exploit leading to full Ps5 JB.

 

[EnderBoy]

Still's necessary a kernel exploit.

 

[Ashigory]

Don't really know what this news implies... does it mean that now it doesn't matter on which OFW version we are? I have my ps5 waiting on 4.51
