Please note, I've seen android devices with x86 processors in them, and that would work a lot better as then the software doesn't even need to emulate the x86 architecture. OK, BIG WALL OF TEXT INBOUND! sorry in advance. Since this can be dome for windows XP, can you possibly follow the same steps and get windows 2000 or possibly 95 on Android?Īnd if so, can going old school make the preformance increase and have it be not as slow? ![]()
