i was working on a translation project for Hyperdimension Neptunia MK2 but i had no time to release it. i was gonna do it this weekend but this news came around and obviously we don't need a translation project anymore. (also thought some of the missing text was inside the eboot and that slowed me down. no text inside the eboot was found at all. i was wrong)
If someone still cares, the Japanese version was playable with English text swapping the Movie.CPK (if you wanted English voices) and Game.CPK (for english text on events) but If you swapped System.CPK, you got some errors like no experience gained, guild menu freezing your game, enemies not doing anything etc.
I used unpack/pack CPK tools to peek inside System.CPK. Yesterday i came to the conclusion a 100% english hybrid couldn't be achieved because for you having the english enemies names you had to use English stCharaMonster.gbin and those freezes the monsters and they cant attack you. also, changing that file alone seemed to cause you gain zero experience.
there is another *.gbin for the Guild Quests. that was the file which made your Guild quests have english text but that file was also the one which caused the game to freeze on the guild menu, so you couldnt have english text on the guild missions at all.
Just wanted to post this
Time to enjoy the game full english (bought a copy a couple of weeks ago but obviously couldn't play it at all)
