Considering buying this flashcart for my 3ds or just getting a dstwo. Real time saving is pretty cool, and I know the dstwo real time saving is very reliable, but how good is it for r4i gold 3ds? Could save me a lot of money by not getting a dstwo. Please note this is in the 3ds flashcarts section and not the ds flashcart section as I am getting this for my 3ds, and this section is much more active
