How compatible is Unwired with SR5?
It's actually one of the
most obsolete books... Since the matrix, in-universe, was overhauled, the majority of what's in that book is irrelevant.
Anything referencing nodes, signal ranges, programs... The entire
Matrix Topology section is no longer accurate.
System Security has some basic ideas that could be translated (things that would reduce Signal could now just cause Noise) but anything referencing IC and matrix attributes will be inaccurate.
The Hacker's Handbook chapter may introduce some concepts that still work (such as Spoofing lifestyles), but any of the mechanical stuff like backdoors, hacked accounts, and all that would need to be re-made entirely for 5th edition because of the introduction of marks as the current form of matrix recognition-- Anything about actual accounts would have to be ad-hoc until Data Trails says how it really works.
Software section is almost entirely obsolete, since matrix actions and programs have been completely revamped. The rule for getting pirates software (1/10th the price, but it degrades over time) could still be applied to skillsoft without changing much. The rules about a TacNet need to be reworked a little bit before they'd work in 5th as well, since PANs work differently.
The
Technomancers section's crunch is mostly useless, but the fluff is relevant, if not currently accurate-- I'm wondering if they will address whether changing how TM's function was a retcon, or if they seriously all evolved with the new matrix; a possible and intriguing concept. Since the TMs are so closely tied to the matrix, and it's established that it did, in-universe, get a big change, I really want this answered. There's no way such a thing just happened without affecting them much. Resonance realms likely won't be too different in 5th edition, so the fluff about them is still usable. Paragons probably didn't just disappear (as that would have been a traumatic event) so transitioning them would be totally within reason.
Sprites; same as TM. Fluff's accurate but could have changed, crunch is outdated entirely.
Matrix Phenomena is mostly for it's fluff, as it's legends and mysterious shit on the matrix. The hard rules on AI's would have changed of course.
Simsense and Skillware? Surprisingly still accurate, I feel.
And of course the
Matrix Gear section is
literally obsolete. All of it could still be found, but anything that deals with the matrix (like the commlink modifications and software) would likely not work unless "updated" properly, which mechanically means it'd have to be remade for 5th. And of course, nanotech is out of the question now.
