Medal of Honor image is 708MB. What CD-R for that ???

[Cabral]

I need a confirmation PLEASE :

Can we or can't we not make backups for all PSX games on 650MB CD-R's ??

Are there any games that need to be copied on 700MB or over CD-R's ??

I was told by BOT-CK that the size of the image doesn't matter since a 700MB and over image will always fit on a 650MB CD-R ? Could anyone confirm this ?

THANK YOU ALL.
