I've read through this topic a bit, and I must say that I agree with the notion of the absurd and outrageous prices. When there were 3-5 listings on eBay for a original 3DS Capture card for 500-600 I even thought it was ridiculous then. I remember when I got mine 3 years ago and I paid the $199 to get it modified for capture card purposes and got then it back within an ample timeframe, a lot of people still wanted them but couldn't get them. And that was a good price in my book. And now with the Keity bankruptcy situation plus sellers asking for $1000+ for a capture card, it's even more difficult to try to get devices in the 3DS era, and I'm pretty sure those listings will not expire anytime soon given the outrageous prices. I'd love to be able to use my New3DSXL for recording content, but I never got a Keity card for those because I was always told there were dozens of issues. So I held off.
Glad to see that it's being worked on. If you do end up making a another batch of the original Old 3DS cards as potentially discussed though, I'd gladly snag one of those too. Could always use a variety of capture cards... just in case
Can't wait for more updates on this!
