1.Is there already a working xbox one emulator?
2. Do you already have a working Ps4 emulator?
3. If no, how long will it take?
There are a number of more or less functional emulators for the XBox. https://emulation.gametechwiki.com/index.php/Xbox_emulators
current versions: https://www.emucr.com/search/label/XBox
However, the list of playable games is very clear.
The promblem here are serious deviations in the hardware structure from the x86 design, which are only very sparse and not openly documented.
A PS4 emulator is currently only in a very early development stage. https://github.com/...7/ps4delta
At the moment it is not about games but the loading of the individual firmware modules. It will probably take a few more years before the first games can be loaded…
