Got a 3DS with V4.5.0-10 as a gift. I'd like to find/use a flashcart with it. I know very little of flashcarts but just from looking at prices and some posts it seems r4i gold 3ds and r4-shdc 3ds are good options. As I understand: 1. NOT all versions of 4i gold 3ds or r4-shdc 3ds are ready (as "plug and play") for V4.5.0-10. They may need to be patched/flashed and for that usually you need another DS (which I don't have access to). Correct? 2. Hence, I need to buy specific versions of these cards 4i gold 3ds (revision "C") or r4-shdc 3ds ("v4.5"), which are ready to be plugged in and work in a V4.5.0-10 system. Correct? 3. When I buy one of these cards, is the micro SD only for the purpose of ROMS? or does it have software used by the flashcart to work with V4.5.0-10? 4. Where can I buy (US shipping) 4i gold 3ds (revision "C") or r4-shdc 3ds ("v4.5") from a trusted site? Again, complete newbie here, trying to understand how to find/use a cart. Thanks.
