Emulation is a grey area at the best of times, but one thing that is a massive no-no is rival companies using the emulated titles of others to promote their own products. We've already seen the team behind the OUYA console attempt to use SNES emulators to sell their micro-console, and now Microsoft is getting in on the act.

The following tweet was posted from the official Surface Twitter account:

The video in question has been posted by a Surface owner, and at 6:50 mark he shows off the fact that the tablet can run SNES ROMs.

While Microsoft hasn't posted the video itself, by promoting it via its Surface Twitter account it's sending out a pretty clear message: our hardware can play those SNES games you know and love, for free.

What are your thoughts about this move? Do you think Microsoft should be let off the hook because it didn't actually post the video itself, or do you think big corporations should be more careful when re-sharing video links via social media? Let us know by leaving a comment below.
