I just so happened to have in my possession, sitting on my hard drive, a game in .img format. So, I burned the CD image in Nero, and it went through the whole process as normal.
Now, I insert the finished CD into my CD-ROM, and there's nothing there. It shows up and everything, you can open it, its just that there isn't a single file or folder to be seen. However, under Properties, it shows up as 100% full. Combined with the fact that Nero didn't take 15 minutes to burn nothng, its quite a mystery.
I should also mention that, being the careless person that I am, I deleted the original .img file. So, I either get this working, or its a 2 day trip back to the Supernova Mart to get a new one.
edit: WinISO and WinAce also see the CD as empty.
