Creating a ISO of any game is a hard task, I will explain a simple way to create working Sega Saturn ISO’s for you to use with a emulator.
First step is to make sure you have a program called CDRWIN it is made by a company called Golden Hawk Technologies, finds this software on google and download it, this is the perfect tool for creating an ISO.
Once you have downloaded the product open it up and lets begin, when the program opens you will only notice a screen of pictures like below.
Click the picture that the arrow is point too this will open up the section we need to create a working ISO.
I have put four arrows pointing to the tools we shall use firstly the top arrow points to the save location of our ISO, I save it to my desktop and enter the games name for example SeagRally.iso < the .iso is very important please make sure with every one you create you put .iso on the end!
Next you will see the arrow pointing to the RAW box which is checked please uncheck this box; the ISO will not work if the RAW box is checked.
The last two arrows point to the start button click this and wait for it to say complete and there you go one fully working game ISO for a Sega Saturn emulator.
