Hi there! I'm having this problem: https://gbatemp.net/threads/acciden...to-10-7-downgrade-with-sysnand-backup.420797/ Or in a few words: I can't access to my JPN 3DS LL (10.7 firm) homebrew using a OoT JPN copy and Powersaves US version (JPN support ended last month, lucky me...) It seems like there's no hope for me? So I was thinking of buying Cyber Save Editor 2 (( http://www.amazon.co.jp/dp/B00LBSLQ...lid=3CRL2SOQVE6WX&coliid=I3PRFCLODTKHS7&psc=1 )), supposedly the 'japanese version' of Datel Action Replay Power Saves. By chance, does anyone know if it works just the same? In the Customer Questions & Answers section of Amazon International (( http://www.amazon.com/CYBER-Editor-Japanese-console-Nintendo-Import/dp/B00CP1308Q )) for Cyber Save Editor one of them is: "Which is better between this and Datel Japan Powersaves? Answer: Cybersavs as it allows things to be written in and inject things in the in some case like pokemon as powersavs only does things like to read and write but no way to inject" So it's even better? Maybe it's my last hope? Or maybe I'm missing something out there? It cost around U$60, plus my trash buy of Powersaves, it would be great if I'm missing something! Thanks a lot for helping me! Edit: Powersaves US works with JPN Zelda OoT3D, can't access cheat codes but you can do what really matters: backup your save file and hax it to access homebrew.
