Funnily enough I just found an interview somebody must have done with me years ago [1]. I forgot I'd done it. There's a screenshot of the Saturn version. If you click through to the 'Saturn Power' magazine scans you'll see the Playstation screenshots [2] (slightly offside that the PS screenshots were sent as an example of the Saturn version!) - it's pretty obvious that the Saturn version looks terrible compared to the PS

Here's my quote re: the Saturn version:

"However the Saturn version was lagging behind quite badly - the textures looked pretty awful because they had to be down-sampled to fit in the smaller texture memory, and the geometry engine was struggling due to the more limited ability of the Saturn"
