Anyone have a dreamcast...

...and have any experience downloading the iso game files and playing them on the console? I downloaded the file parts, expanded them with winrar and burned them to a disk. It will not play, and I have a feeling that I need some sort of boot files or something... I just used std burning software, and most suggest alcohol 120% to do the burning.. Not sure why but I have a feeling it may help?

I am currently searching emuparadise forums, but my computer experience is below novice, more like tard.
