Dreamcast is totally different though, more recent rips have been done in the best possible format, most games though actually fit without any removing of data or re-sampling, but yeah there are games that can not fit onto a standard CD-R, another but... there are some 99min CD-R rips that again have managed to do so with no removing of data or re-sampling and there are even spanned games, e.g. I put Grandia II on to 3CD's that is a single GD-Rom originally and was normally either ripped on to a single CD with heavy down-sampling or onto 2 CD's with less down-sampling, my 3 CD rip has nothing re-sampled in it, there is a small edit to replace some map text that indicates when/where to save your game to boot the next disc (saves you having to guess when to save or read spoilers that tell you when to save) but asides from that it's a perfect rip, there are still a few games that have re-sampled data in them or removed data to make the games fit but very very few now left like that.
Even most of the PS2 DVD9 to DVD5 rips are much the same, as far as game data goes they are perfect, some just remove other language files, such as JAP text or voices and/or vice versa for those games with both Jap and English in them, most span over several DVD's and preserve all the game data
