So, there's an English-hacked (unofficial) firmware out ... question is, can it be installed on the English M3 Real? Because as stated here, it seems like the unofficial firmware will only be installed on a Japanese M3 Real; does that mean I have to import a Japanese M3 Real then? Also, back when Sakura was still in beta, I thought it was a .NDS file and can be booted in other flash carts (just no commercial-ROM support); what happened to that? Is it no longer a .NDS file, and that's why it cannot be booted off by other flash carts? I'm currently deciding on which NDS flashcart to buy, and M3 Real seems like it, but I just need to confirm this.
