Already programmed. Shipping not included.
Two versions: 3DS is the same as before. DS unmaps the Home button pad, the left stick is set to the dpad, and the right stick is set to ABXY. They can still be changed. Comes with a pull-up resistor for the Home button if you're going to install it in a DS; it's needed for remapping buttons.
Also offering installations for DS, 3DS XL, and New 3DS XL. Other consoles later.
For DS, currently I'm only willing to do it if it has a capture card installed (or you're going to get one installed) because I'd rather take over the original charge port than cut an awkward opening for it.
DM me here or on Discord. Price negotiable if you want several.
