I took a look at the Romancing Saga 2 Vita ISO (JPN) with the help of the person who did the "I Am Setsuna" translation (We translated on the PSP together: Half A Minute Hero 2, La Pucelle: Ragnarok, Phantom Kingdom Portable). We tried playing around with swapping the assets in the unity engine. The english for the menus, items, weapons and etc is in the original JPN ISO that can run on 3.60 firmware. The MAI dump seems to have problems working because of bad dumps in the sce_module but the NoNpDrm dump works great.
You can switch these assets easily from the JPN and ENG by swapping them in the Unity assets using AssetsBundleExtractor (https://7daystodie.com/forums/showthread.php?22675-Unity-Assets-Bundle-Extractor). I can confirm that you can get this working on the Vita. These assets do not include any of the story text.
I think there might be a flag somewhere in the eboot.bin to set language to JPN or ENG but without an emulator/debugger will be almost impossible to find.
We also have tried inserting the Unity assets from the android release and the steam release into the Vita 3.6 ISO and cannot get it working.
We think the issue is with the data.bin and data.idx that has Vita specific files in it. Looking at the files size (data.bin) for the three different releases they are all vastly different as well.
We think these two files hold the story and are key to getting this translation working in the JPN ISO. It will be a ton of work to figure out how these files work. The other option is if we could get these files (along with the Unity files) from the Vita ENG Romancing Saga 2 game then we might be able to insert them into the JPN one.
If anyone has any idea how these file formats work or if you can get the RMS2 ENG iso (I know it will not run currently with Henkaku since its above 3.60+ firmware), please contact us. I doubt people are trying to dump these type of ISO since they cannot be played with Henkaku. We are lurking around the normal boards and forums.
