First, I'm very sorry for asking such a shitty question here. But I'm really new for flash cart. and Title is my question. I'm very interested in the TWL module patch. so I would like to buy flash cart. why R4? because the price is 7 US dollar. http://www.ndswayz.com/product-148.html (Japanese) I have a9lh installed New 3DS version 11.0. Luma3DSDev nightly build has been installed. Thank you.
