Looking into buying a 3DS, could use some advice
Since late last year I've owned an R4 flash card that I've used with my DS Lite. Its been great for games and having 40+ games on the go, however, I'd like to do the same with a 3DS. I know I'll have to purchase a new flash card for it to be compatible with the 3DS and play my DS Lite games/use homebrew, etc., but I'd just like a few questions answered and possibly a bit of help.
I've already bought a few 3DS games to start off my 3DS collection, however I use my current R4 to read eBooks and play quite a few DS games. I'll be trading in my Lite towards the purchase of a 3DS, so I'd hate to upgrade and then be put out as far as DS games and eBooks are concerned. Basically what I'd like to be able to do is play the 3DS as normal as far as 3DS gaming goes, system updates, using the eShop, etc., but be able to take out a 3DS game, pop in my flash card and load up a DS game, or read an eBook... so is this possible as it is on the DS Lite?
How risky is using a flash card with the 3DS? I haven't ran into any problems with the Lite, of course, but the 3DS is a much more complex system. In the same train of thought, is it possible to buy a flash card, get it working, but have the 3DS' firmware block it out? I'd hate to buy a flash card only to have it blocked, but I don't know if simply not updating the 3DS is an option. The only games I'd be playing online would be Pokemon White (White 2 later this year) and Mario Kart 7.
Which flash card is most recommended? Personally, I'd love to get one that will do everything I'm currently doing with my DS Lite, but has the possibility to, hopefully in the future, back up any current 3DS games I own and throw 'em on the flash card, though I'm in no rush for the option. Like I said, I just want a 3DS and to be able to do all that I do now with my DS Lite, but have the option to play 3DS games.
Lastly, could anybody recommend a reputable online dealer to purchase from? I originally got my DSL R4 from ConsoleSource, but they seem to be down, at the moment.
Sorry for the lengthy questions, in particular the first one that tends to rabble on and on, lol. But I thank everyone in advance for your time as well as your help.
