I confirm this works.
Also AQEJ610220 cart purchased on launch Nov 2011. Transferred save with DATEL Powersave PRO. Regular JP OOT save from Gateway team corrupted, fixed save works! Thank you.
I too received the notification from Amazon of delayed release! I think OP should be updated, here is the news: http://www.nintendolife.com/news/2015/08/rumour_rodea_the_sky_soldier_release_pushed_back_to_november
Will it work if donor is a broken o3ds on 4.5 fw? It wont read carts otherwise works. &does it matter if donor system was connected to internet and nnid?
