I lost access to MEGA folders that used to store collection.
Is there someone who dowloaded files from it and may be still has them on disk ?
Bit late, but I believe I have the files for some of the older games - Girls Kingdom, Brave Girl Ravens, and Dragon Tactics: Memories, if you need those.
Personal favorites, by game:
Millennium War Aigis (RIP): Liana
Girls Kingdom (RIP): Iris
Dragon Tactics: Memories (RIP): Diske
Brave Girl Ravens xR (RIP): Francette
...Most of the games I play on Nutaku end up getting taken down. Hmm.
