Help concerning Umineko PSP Translation

[Beegee7730]

Hey all, I need some help.

So I've been messing around with the PSP version of Umineko No Naku Koro Ni, and I've found that most of the text in the game is stored uncompressed in one large .bin file. It's easy to edit and I have already replaced some of the Japanese text with english.



My plan was to just use the Shift-JIS romanji characters to translate, but I have a problem. Of course, kanji/higa/kata take up two bytes, as does Shift-JIS. That means that I have half as much space to input text as before. Now my plan was to simply expand the script and continue using Shift-JIS - Inefficient but easy enough to do for this. (Of course, the best solution would be a "true" translation to romanji style characters but that's beyond my ability)
Anyway, my problem is that when I attempt to expand the file by inserting text through the hex editor, it causes the game to crash/black screen. Now I'm not sure why it does this and I wanted to find out why.

Can anyone offer me any advice?

Sorry about my crappy explanation by the way, if you need any clarification feel free to ask.

How are you editing the file? Extract file, edit, recompile ISO with the new file?
Check to see if there is anything defining the size of the file, maybe in the header or some other file.

This. Alot of games for PSP are LBA-protected, meaning that is any of the file sizes or locations are changed, it breaks the game.
Supposedly, you can circumvent this by using WQSG_UMD_R31 to re-compile your .ISO, but I can't say for sure, as I've never tried it (UMDGen has a setting to make things end up in their proper LBA locations).
But ya never know. Give it a shot.

Thanks for the advice.
I thought it may be LBA as I've had issues with LBA before. I tried both the filelist option in UMDGen and using WQSG_UMD (Though I'm not sure I was using it correctly) and both still black screen when loading. I assume this could be as I am expanding the ISO, and not just dummying and relinking files?
Are there any guides for how to use WQSG_UMD? I feel I could probably fix the ISO if I knew how to use it properly and how to expand the LBA.
Thanks!

Edit:
Feel free to let me know if this is getting close to breaking any rules, I know it can be a touchy subject.
Is BOOT.BIN related to the decrypted EBOOT.BIN? I decrypted it and re-inserted it into the ISO (despite the fact that the size is totally different and would normally screw up the LBA) and the ISO runs without any issues. Anyway, I digress.
I decrypted the EBOOT.BIN and made some simple changes. For example, I changed the path from "SCR.BIN" (Script file) to "SCE.BIN". It works fine and has no issues. However, if I try and expand the EBOOT.BIN, For example, changing the path to "SCER.BIN" it just crashes, making me believe, of course, LBA.
