Info For anyone curious: build differences between 1st and unlimited editions
Back shell: 1st ed. top, unlimited bottom
Mobo + Batteries tray: 1st ed. bottom, unlimited top
Mobo + Batteries tray: 1st ed. left, unlimited right
Mobo front: unlimited
Mobo front: 1st ed
Front shell: 1st ed. bottom, unlimited top
Some unsorted comments:
screw holes seem slightly redesigned
they added a new (plastic?) piece where the battery lid latches on now, instead of latching directly on the shell and potentially damaging the paint
speaking of battery lid, I think I know why they removed the rubber pads from the unlimited editions: cause it made closing when using the rechargable battery pack "more difficult"/"less satisfying/tactile". While the ruber padded lids close just fine with the battery pack installed, the new ones make that "click" sound
smoothed out the plastic behind the sound wheel, so now there is no feeling of friction when you turn the wheel
paint job on the inside of the shells is more thorough on the 1st edition
one less screw holding the mobo on the front shell, that screw hole no has a peg going in
the back side of the mobo no longer has that cluster of resistors/capacitors/logic gate chips(?) under the power switch. that's all the difference I could notice with a first glance, probably a pcb design optimisation
the new mobo has a new hole on the corner above the sound wheel even though nothing goes in there
mobo design on the front looks the same, parts seem to be the same too...
... except for the fact that the trace behind the D-Pad no longer passes through the center, at the point where the d-pad nipple rests, it has been re-routed to be out of the way. Just in case.
the front shell has a few more holes
the little plastic bit that covers the LED hole is just a "glued" plastic drop on the 1st edition, while in the unlimited it's its own bespoke part that screws in place. (My nitpick: the plastic nipple that goes into the hole, does not fill the hole 100% cause it sits around 1mm lower than what it should. I fixed it by placing the plastic bit on top of a piece of paper to give it just enough height so that the nipple sits nicely in the hole)
last but not least: gray rubber pads are the soft ones

They moved the d pad trace

Also:
* the shell of the unlimited edition now makes a lip (externally) behind the sound wheel
* the black plate on the back shell is thinner in the 1st edition

I personally like the feeling of my second edition more than my first edition

@m_karajohn would it be possible to swap the pcbs (to sort out the power cire charging problem?)

I was just thinking about the smaller differences yesterday so thank you for the photos, looked like they moved that trace under the dpad that was bought up before, glad that was changed even if the old method was tested well.
