I posted about the best emulator to use in another thread but I was still unable to get any of them to work, though SSF was meant to be the best one, of which I had placed my cards on after the advice I was given.

Now I found and bought a physical Saturn on Amazon so now the question is; Is it possible to burn my Saturn ISO files, namely Sonic R and Sonic 3D Blast to CDs and will these be compatible/work with the Saturn itself?

It's only a temporary measure until such time as I can track down and buy actual disks of the games as I was going to save up for a physical Dreamcast as well and I'd want to do the same thing with my ISO files of Sonic Adventure 1 (1998 Version), Sonic Adventure 2, Revolt and Shenmue Undub. They might be harder however as Dreamcast games use Gigabyte Disk (GD) ROMs and I don't know where to get blank ones from nor how to burn the disks.

Other games I want like Croc, Rayman, Tomb Raider 1 Saturn and Burning Rangers I can just buy from the get go.

Is your Saturn modified? You won't be able to just play burned discs without modding the system, as the discs are copy-protected.

This might help with burning:

Dunno. It hasn't arrived yet; I ordered it several hours ago at time of writing. Thanks for the link.

I'd tread lightly on this topic, the thread is likely to be locked since it's technically discussion of piracy.

Bizhawk and Mednafen are better overall if you still want to try that. I'd recommend Retroarch (which I think used the mednafen core) too but it didn't work for me on Win 10.

I don't need emulators now because I've ordered a physical Saturn. I just wanted to know if I could burn the ISOs I currently have as a temorary solution for when it arrives. I'm actually looking at prices for the actual games right now. So far I have bought Sonic R but I need to save up for the others I want.

Good. I can always buy a memory card if my current system doesn't have one. It's now been dispatched.

EDIT: I've gone for Action Replay 4M Auto Plus. That way I can play games region free, like the Japanese copies of some games. (And even the French version of Rayman)
