The NeoSD is why I'm back into Neo Geo now (having previously sold off my CMVS and CD units years ago) and by extension this site as well (though, I had to make a new user name as it's been so long since I've been here I don't have a damned clue what it is anymore), so don't feel bad at all.
I don't typically like Everdrives, as I do like having original carts and if I can afford them, boxes and manuals. But for things like the Saturn, PC Engine and Neo Geo where collectors and scalpers have made collecting a freakin joke, I support such devices fully. I wanted to get back into Saturn recently, and my jaw about hit the floor when I checked to see games that I had just bought for about 20 bucks 3-4 years ago going for a few hundred bucks a piece, and ended up simply getting a Rhea SD card board instead. Like the Neo SD, it was about 4-500 bucks, but it beats paying nearly that for a boxed copy of a couple RPGs or fighting games.
