I decided its about time to pick up some flashcards for my DS lite and had some questions. The carts I am looking at getting are a R4i Gold 3DS RTS and a EZ 3-in-1 Expansion Pack/EZ-FLASH IV. My understanding is they are the best cards at the moment unless you want to use emulation on a Supercard DSTWO PLUS. Is this correct? Does any one know where I can find some good up to date usage guides or the manuals for them? I could not seem to find them on the official websites. Next how is the EZ-FLASH IV vs the EZ 3-in-1 Expansion Pack? its not that much more expensive and it supports cheats and works on GBA but I thought I rememer it being a pain to work with. Maybe something about having to use special software to transfer things over but I cant quite remember. Will a 64GB FAT32 formatted micro SD card work properly in a R4i Gold 3DS RTS or do i need to use a 32GB or less SD card? Also how is the game compatibility on these carts will most things just work properly out of the box? Finally are there any reputable and fast USA based sellers because I have heard nds-card.com can be a bit slow at times. Sorry for the long list of questions and thanks for the help. Edit: I am pretty sure I have figured out some of the stuff but I still have two major ones I would like have answered before I shell out the cash and order them. 1. Where can I find updated manuals or guides for the R4i Gold 3DS RTS and the EZ 3-in-1 Expansion Pack? 2. Will a 64GB FAT32 formatted micro SD card work properly in a R4i Gold 3DS RTS?
