PSX Games Bigger than 650Mb?

[Red Pepper]

Hi, I hope this isn't a stupid question or one that's been asked before,

I just made a backup disc image up of 'Medal of Honour Underground' PSX, using CloneCD, and the .CCD file appears to be about 700Mb in size. Will it write onto a normal 74minute 650mb blank disc or do I need to buy an 80minute one? I've never come across a PSX game b4 that wouldn't fit on a 74 min CD, do they exist / are they common?

Thanks, Red Pepper
