When i ordered mine, i also just had them include the files ready to go on a floppy. I think it was a buck or two more but saved me the hassle of figuring that out. Let me know how it goes.
I would just keep eBay and AtariAge separate. There is no reason to promote an auction here on forums at all, since you have an audience consisting of millions on eBay. It also keeps issues and responses like that from happening.
Thank you, i passed right by it! Even though i have boxes for alot of my games, i just flatten them and store them. I use these universal cases for all my carts.
