When you download an ISO sometimes, what are the different parts (Part 1, Part 2, etc.) and what do you do with them. I guess what I'm asking is, how do you make it play like it is all one single game?

use a program called hjsplit to join the 2 parts together

Most of the time you just need to open Part1 with WinRAR and extract the ISO from inside that file, it should automatically link all the parts together to a .iso or .cso file.

k, heres what i do. Put them into the same folder, al the parts, then highlight them all, crt (then click on each one, which will stay highlighed) then right click and say extract here, if there a pass it will ask u a couple times depending on how many parts. it works for me. i ve done it twice, but i like to stay away from parts becuase they are usully bigger. k
