When I was browsing the Operating systems download section, I saw information about downloading an emulation for a Macintosh on stick. I then thought wouldn't it be wonderful if windows was on a stick! I did a search, and what do you know! There is a legal version of Windows CE emulator in Windows to download. It needed no ROMS, etc, and as soon as the instructions were followed, it worked! Could someone add it to the list!
