Recently, the market of 3DS flashcart is quite hot. GW officially said that its new release not long away will support 7.0.0, on the other hand, the newcomer 3dslink videoed ahead of GW that its 3.0 will also support 7.0.0. Relatively, R4i is more low-key and seems to stay very calm.This made me recall the Big Bang. Leonard is just like GW, while Leonard is just like 3DSlink, both intelligence higher than the average. But Leonard is a bit mature than Sheldon. Sheldon's success seems more easier than Leonard.They both very smart.R4i is more like Rajesh Koothrappali, he is very careful and prudent.
