sorry my phone was being stupid haha. I was trying to say that
some applications may "break" either partially or all together with the upgrade, but that's to be expected with ANY OS upgrade.
It however won't break emulation as a whole, that's just silly
. If some emulators temporarily lose compatibility with the upgrade, it will just take some minor tweaking to get it going again. Most emulators will probably run fine though, if they run on 8.1 no problem.
@Arras NT is based on Unix. What I was getting at is that all modern OS's are ultimately based on Unix ever since the XP days.
