Discussion of Theories for Newer PS4 Games on 4.05 Firmware

Following the recent PS4 Barthen Method for getting newer games running with PS4HEN, some forum members including @SkysTheLimit, @Goldenboy22 and @Picalo would like to open a discussion of theories on how newer PlayStation 4 game dumps can become playable on exploited 4.05 Firmware consoles.

We'll use this as an ongoing discussion thread for those who'd like to share their insight and research into getting newer PS4 games with Minimum Firmware Versions above 4.05 OFW dumped and running, which according to Mathieulh is currently the BEST PS4 Firmware to be on as 1.76 is now considered outdated since the 4.05 exploit chain from SpecterDev with popular 4.05 exploit forks and experiments by IDC alongside the PS4 Exploit Host by Al Azif.

Here are links to some current theories from the Barthen Method topic:

• From Goldenboy22
• From SkysTheLimit
• From Picalo
• Follow up by SkysTheLimit

Finally, below are some other PS4 MEME and Tweets making rounds on Twitter today:
Cheers to @B7U3 C50SS and @SSShowmik for tips in the PSXHAX Shoutbox!

was refering to the person who stated we need cfw. a little homework to understand what it takes to make emu to run games or anything else you want to build comes from within a game itself

then the syscalls are added seperately

Hello @Chaos Kid
the cfw would be the solution to all game compatibility issues and maybe who knows what
but has it the way of existing and being created ???
that you know someone is working on it ???
if so, it is useless to think of a way to bypass the fw control

 

[salah 360]

Why these not they release the exploit and makes it private ? There are poor people who want to play

 

[Caelbrazil]

True, I agree with you that you should release cfw to people who need it most to play, poor people have dreams too, and good-hearted devs could play ps4 cfw.

@73n1x69 Wrong

@boybergamo76 Dear, i've attached a screenshot with a UART log that proves what i said about function call not found by high FW games...

And that's not something said by me , but from other very skilled people

 

[phaedrus]

We not see UART log, please extra nice if possible share. Always happy see debug, understand more.

If game code call function in >4.05 API, yes. If game lazy repack for meet SCE release firmware requirement, not call new function, 4.05 happy, unless function call move memory location change firmware, but function call abstract this runtime, not compile in.
All game >4.05 perhaps not make 4.05, key All, some resign key 4.05 work.

Still case we know not if SAMU key change each release, or only major versions. Window 4.05 working open more if not.
Window open small amount each discovery. Each time more light into scene.

As the video shows he isntalls the game from the original bd, and is able to execute it using the latest vr payload, if it is true

 

[showmethehax]

Legit?
