I'm looking to build a custom [save] dumping device using a microcontroller, and I already have a decent understanding of the software side of things and how to implement it, but the one thing I can't find is a suitable socket to actually read cards. Ideally it would be a through-hole soldered variety as used on the NDS Adapter Plus, instead of the surface-mount type as used in actual consoles. I imagine it would be fairly easy to buy something suitable in bulk from some obscure Chinese company, but I will only ever need one of them. Any idea where I could buy one (or a reasonably small quantity) of these? PS:I know this isn't really related to flash carts at all, nor is it really suited to this community as a whole, but I'm hoping someone here might have an answer. If not, feel free to redirect me to the right place. EDIT: [Mostly copied from comment] After looking more into how ROM dumping works, I realised it wouldn't be practical as a side project like I intended, but I now think I may still try for a save dumper. I may alternatively build a standalone device with a simple input panel to write saves to/from an external USB storage device for backups, or micro SD card for direct use in flashcarts.
