Looks good!

Maybe you should start with Win1.0, it isn't a stack-like OS(notice how you can stack Windows on top of Windows), instead it works with the applications being tiles. Windows 10 is also too powerful for the o3DS/n3DS(my PC has 4gb, and it doesn't even keep up with memory most of the time). If you don't know Win1.0 looks or works, it's on WinWorldPc(VMs) and you can try it online: PCJS.org

you see its a FAKE sim. it would never run the real 10... and windows 3.0 would be good next.

Oh, ok ;) At least you know have a reference to take from. Just get VirtualBox & you can install the Windows available on winworldpc.com, I use this a lot btw.
