He is right, current flash carts only work for the 3DS firmware 4.5 and below. Using exploits which only work for firmware 4.5, they are able to emulate higher firmware versions.
I wouldn't be so sure, Nintendo has done a really great job thwarting modding on the 3DS platform.
Sorry to hijack this thread...but,
What link you guys got for flashcarts that work on the 3DS? I thought we could only use the SD card slot and 2DS games only. I'm going to get some reading done today if things changed.
Great price for this deal repped
, IMO 3DS should settle down to $140 range for the duration of its lifespan.
