I thought my game has encryption because i saw wamsoft inside the extracted files. So I always named my patch unencrypted.xp3. turns out that it actually needs to be patch.xp3. I just messed up when making my first patch. But in the end, it worked! And i learned something new. Thanks for the help!
The new 9 nine game, also wamsoft. I already extracted and translated the dialogue files. I just need to compile it to a .xp3 format but the patch i made using kirikiri tools doesn't work.
