I would really like to see an idea like this come to frutition because it would be a quick and easy to have cartridge games without all the hassle of the games taking up space. They would be easier to store and carry around on the go.
Here is a step by step process of what I imagine this project would be developed:
First, save and store each VC title to its own SD card. Each SD card mustbe big enough to store the game, but small enough that massive amounts of storage is not wasted in the process. For example, suppose Sonic the Hedgehog 2 for Genesis is 12.5 Megabytes, put it on a 16 MB SD card.
Secondly, get a hold of a collection of slim DVD cases modified to hold SD cards.
Lastly, Print your labels for each VC title and place them into individual slim DVD cases modified to hold SD cards. Now the project is complete.
