I went to http://eng.supercard.sc/manual/dstwo/download.htm and 'Download' link (not the button on the right). I have 7 Zip so I dragged Moonshell, NDSGBA, and ds_two into the microSD card. Then I put a game. I then turned on my DS, entered the DSTwo, pressed DS_Game and selected a game and it played perfectly. This is my first flashcart and from a lot of guides online I thought it was going to be very frustrating and confusing but I did it easily. I'm just wondering if perhaps I may have missed something? Is what I did perfectly alright to ensure no damage to the flashcart or system? Also what does it mean to "flash a DS"? Does DSTwo do that? I heard that voids the warranty. And can I just shut off the system like with normal games? or is there a process to exit the DSTwo before I shut down everything? When there's a firmware update, how do I do that? Just replace the ds_two file? Like if I were to go back and click on that button at http://eng.supercard.sc/manual/dstwo/download.htm for the most recent EOS, would all I have to do to get it updated is remove the one currently in my microSD card and replace it with the new one? If I just turn off the game, I notice 'sav' files appear in the microSD card. Does that mean the games remain where I turned them off at? Can I get into those files or should I just delete them?
