If you do decide to give the PlayStation thing a go, you'd be best off with the first of the games
TT SuperBikes by Jester Interactive
It came out in 2005 and has a GSXR1000 K3 on the cover.

The second of the games, TT SuperBikes: Real Road Racing Championship is a bit more of a handful, and you'd most likely spend your time trying to figure out how to simply keep the bike on the road, rather than actually learning the track.

The track itself is accurate enough, in my opinion, to give you a good understanding.
However, it is a game, and as such has a few glitches.

I think that it would be of value to use this game in your learning of the course, because unlike watching an onboard lap, the game actually engages you.

Over the last few years I've set off down Bray Hill, virtually, thousands of times.
I am now able to watch onboard laps, even if the camera is pointed at the riders visor,
and keep track of where I am on the course.

I've seen copies on EBay recently for about ten quid.
After that, all you need is a functioning PS2
If you'd like to know anything more about the game(s), say the word.

And, back in the real world, Best of luck
