Where can I find roadrash game? Can I run it on Win 7?

You can find here a screenshot from the bike racing game on pc.

Where can I find full free version (all five levels) to download? I guess the set up file is around 20 MB.
I have downloaded it, but when run on my Windows 7 home basic edition (64 bit), it runs but I cannot see it normally. I mean the game starts all right, but when I start the race, the graphic is really bad – like full of noise (photoshop term) and a bit of negative. The game runs on maximum 600×448 or so resolution and I have minimum of 800. Can I resolve this? Or have I downloaded wrong set up file? Is then there right file?

By the way, do you play it? Like it?

Thanks in advance.
