Yes
Yes. DeSmuME does.
It depends on what kind of version you have but most of them work perfectly
No, because Pokemon red's emulator is for Nintendo products only not Xbox whixh is owned by Microsoft. It just would not work. you can play Pokemon red on xbox using xbox emulator, just send emulator and the ROM to your xbox and start it.......
Most BNSF emulators will work on Windows 7. You may have to adjust how it runs, use compatability mode or other workarounds for some emulators, but they will eventually work.
No, becuase Xbox 360 uses a different emulator which is not made for pc
You can't do this, software written for windows will not work on a Mac unless you load a windows emulator on the Mac first and even then it may not work well. For software to work on the two architectures, you need to compile it for them and only the vendors can do this.
Usually no. You would require a windows emulator, and even then not all games would work.
Some can be downloaded via the wii shopping channel (for a price), or they can be played via an emulator on modded wiis.
No PS2game do not work in Windows. Some can be made to sort of work with a PCSX2 emulator, but it is not like playing them in a PS2. The game discs must be downloaded and files created and you also need to have a PS2 to transfer the bios.
There is no method of running Mac programs directly on Windows. it is only possible inside an emulator, which is very slow and useless for multimedia work.
Well, you need to be jailbroken with Cydia, but that will void your warranty. Also, there is not an emulator for the DS yet on the iPhone, but I've seen footage of one (Doesn't work very well/probably fake). Also, emulators are illegal.
There is currently no functional PlayStation 3 emulator in existence.
