Sorry to bump an old thread, but I have tried to install a forwarder using the Haxchi method for Sign C2W patcher. Downloaded the pack for Sign C2W patcher provided in the first post and checked all the settings (they are all the same), installed it over "Big Brain Academy" (Pal version, installed on the NAND, got it from USB helper). But when I launch the forwarder it gives me the boot up image and then turns into a black screen. Does anyone have tips for me to actually get this thing working?
I am on Tiramisu, so I am not using any DS title yet. I just don't understand why it doesn't work.
