ELI5: Why it's so difficult to make Xbox 360/PS3 emulators for PC.
gpt
Well first off an Emulator for a game console is a software that is replicating the hardware that is being used in the console and its operating system.

Old machines we're easy to do this with such as the GameCube and N64 because they we're inexpensive and simple machines.

Microsoft and Sony however have spent money and time protecting their software and hardware and actively do so. This makes it difficult for someone to accurately replicate their safety precautions and encryption data. 

Once the 360 and ps3 have lost their spotlight and support, the hardware and software will stop receiving updates and will be easier to replicate. 

Also microsoft and sony lawyers won't be so quick to threaten anyone who tries ;)
