It has came to my attention that some of the people who purchased one of the R6 Gold or Silver cards, are using flashcards for the first time. So here is a quick guide for those who are unsure about how to get them working properly.
First you will need to set up your MicroSD card, also called TF (Trans Flash) card. First download the R6 firmware, this may have came on a cd in the R6 package, but it may not have. Either way, you can download the latest version from the Neoflash forum, there is a selection of R6 compatable software (including the latest firmware)
here and all of the previous versions of the firmware can be found
here.
Unzip the software to the root of the TF/MicroSD card, there should be a moonshell folder and application (moonshell-r6.nds) this is a very popular media player to the NintendoDS, it is not vital to the function of the R6 range, but it is a good thing to have for playing mp3's or dpg movies. Also you will see _boot_ds.nds, which it the actual menu for the R6 and something similar to 'r6boot-2.0070-selfburn_for R6.nds', this is the bootstrap for the R6 card.
You are now ready to test out the R6, when you boot up your DS, you should see a list of all of the files on your TF/MicroSD card, at this point, it is recommended that you run r6boot-2.0070-selfburn_for R6.nds as it will ensure that your R6 will work with a wide range of TF/MicroSD cards.
WARNING! never switch off or reset your DS while the r6boot-2.0070-selfburn_for R6.nds is running, you will risk damaging your R6 card and you may need a second flash card to repair it.
You are now ready to add your games to the card, there are load of homebrew websites, offering thousands of free home-made games for the Nintendo DS. Unfortunately I can not, for many legal reasons tell you where to get commercial games from, as downloading commercial games is illegal (even if you own the original cart) and in a lot of countries it is also illegal to make your own backups directly from the carts you own. That being said, once you have obtained the games, put them onto your card, be sure that they have a .nds extension on the filename, if they do not, they might be compressed (e.g. .zip or .rar) you should use a compression program to extract the .ndss file(s) from the .zip. A lot of people recommend using winrar or winzip for doing that.
Now boot up your DS, you should be presented again with a list of files on your card. Just select the game you want to load and press 'A'. Currently there is more than one hardware revision of the R6 Gold/Silver, and we can not guarantee that every version of the menu will work with every R6 card. IF you find that you can not load commercial games with the current version of the menu, you can try earlier versions, they might work a bit better. The Neo team are working on this problem, so there will some a time when the latest menu will work on all versions of the R6 card, please be patient.
If anyone has any other [constructive] advice, please feel free to post it in this thread.
