Yes. That's the gist of it basically. Of course, if the games has separeate CDDA tracks (audio is on a totally different track and not in the game data), you'd burn the games as a Mixed CD (Data+Audio). However, sometimes it's not that simple because some PSX games have all kinds of protections (dummy files, subchannel data, corrupt/weak sectors, etc.). The real problem is that even if "advanced" burning programs such as CloneCD that support PSX CD formats, the CD burner you have might not be able to read/write these oddities. So, often times, just burning the disc won't do, and you have to start hunting for programs that alter the data before you burn it (they aren't hard to find though, a lot of sites have PSX backup fixes; PAL/NTSC switches/converters, trainers, protection removing and so on and so forth).
