previous update, PlayStation 4 developer @SpecterDev tweeted that he's currently having System Call fun through reverse-engineering the PS4, and when asked by @kazookid0 which Firmware he was running he confirmed 3.55 in the Shoutbox which is always GREAT to hear as he did develop the PS4 Playground for Firmware 3.55!
In related PS4 hacking news @bodeg spotted THIS reply from developer Yifan Lu which touches upon the feasibility of PS4 support for taiHEN- the Custom Firmware Framework that supports Adrenaline 6.61 PSPemu CFW on PS Vita... here's what he had to say, to quote:
"This one is unlikely to be taken on by me. The PS4's kernel APIs should be close enough (have same/similar functions) where a port of taiHEN to PS4 would be easier than, say, Android. substitute supports x86-64 as well.
For anyone interested, to start, they should try to build taihen without linking to the stubs. GCC will then complain about undefined symbols. See if you can find those functions in the PS4 kernel. My suspicions is that you can find most of them (and we don't use that many kernel apis)."
Sony must be pulling their hair out lately, from the recent PS3 Hacks through Native PS4 Calls to PS4Link Peek & Poke support.
