Ripping textures from Thunder Force IV

[manure]

Hello,

I'm a french electronic musician, and I would love to use a texture of the game Thunder Force IV for an album.




Here is the zone, I would like to retrieve the entire landscape behind. 

Would it be possible??

And an other thing, I tried several times to contact Sega to ask them for their permission, unsuccessful. Any tips for contact them? Or is it OK if I use it for a public release without a reply for them?


Thanks you fellows,

Benoit.
