Oh, you should know, R4DS wasn't always about $6.All I hope is the crown3ds price is cheap like R4.
When they came around in 2007, I paid $65 for an R4DS and a 1gb microSD card. They were both pretty new technologies at the time so they weren't cheap.
I can imagine Crown3DS as a premiere 3DS flashcart solution would not be cheap (or whatever comes out first), and they'd have to work on SDXC support as SDHC memory is bound to 32gb, some 3DS games are already 4gb, and often sit around 512mb to 1gb easily.
Doesn't matter. If the Crown3DS is what it claims it'll only hold 1 game at a time. SDHC is more than enough for that. Still, it wouldn't be cheap. I could see upwards of $100 but possibly as much as $200.
I remember when the original R4DS could be found on eBay xD Some sold for $80+.
