Thanks for your reply, I want to put 3DS games on the internal memory (that's the 32gb Micro SD card isn't it?), but the link you gave me in your first reply says it only works up to 11.13.0 and I have 11.13.0-45E. I'm happy to purchase an R4 card to do this, but could you point me in the direction of a CFW tutorial for my 11.13.0-45E device using an R4 like you said?
Thanks a lot for your help!
The 32 GB microSD is indeed the internal memory card you would install the games on. Upgrading is really easy if you ever decide to get a bigger microSD card.
Using that guide will work on 11.13.0-45E. If you look at the
first page, it says "CFW can be set up on any console on any version (but may require additional tools / accessories for versions >11.3.0)."
Furthermore, on the
Getting Started page, you'll read that in the table for compatibility of firmware and what method to use the 'from' and 'to' columns are inclusive, so they go from and including up to and including certain firmware.
As far as I understand, 11.13.0-45E means you are on official firmware 11.13.0 and the -45 means you have a browser installed (because it's not -0) and I believe the E means you have firmware for the European region.
In conclusion, I think you can use the CFW method for firmware from 11.12.0 up to and including 11.13.0 (Seedminer, which I have never done) or use an All Versions method (ntrboot, which requires a flashcard and I have done multiple times before.)
If you want to see which flashcard comes preflashed with ntrboot, look on the
ntrboot page.
EDIT: Browsing the Ebay UK, I think I see a good one
here (the Grey version is RTS, and on the ntrboot page it says all RTS versions are compatible). It's a UK seller selling for 6 Pounds Sterling plus whatever postage they ask. DISCLAIMER: I am neither the seller nor do I know them, and I can therefore not guarantee the card is genuine or vouch for the seller. Maybe check their feedback first.
In general, try and refrain from buying cards from Asian regions, as I hear a large proportion of fake cards stems from that internet sellers out of that region.
