Hang on.....a typical NES rom is about 20-60mb depending on title. A blank CD-r holds 700mb of storage. So you can't fit the entire NES library on a single CD-r, but I feel like you can fit every game that you're realistically going to play. So in that sense, I get it. But what I don't get is this doesn't use the expansion port. It uses a USB cable to connect to an everdrive.
If you're going to use an everdrive either way, what is the point? Just put all the roms on the everdrive. Which I assume you can use any microSD card. At that point you CAN fit every single game ever for the NES onto the everdrive. I don't recommend that. It's technically superior, but I find having a smaller personally curated list of games to be better for finding a game you want to play, fast.
Even so, I still find zero advantages of using this. Am I missing the point? Is there some context I don't get? I read the article. Even if it used the expansion port, then it becomes cool in a "what if?" sort of way, rather than a realistically useful way.
But this just looks bulky, uneeded, and I don't see the advantage to doing this.
