PS Vita - How to edit eboot strings and spr4 files?

[olive hemlock]

Hi!
I'm translating P4D rn, but I have some issues: There are hardcoded texts in the eboot file, I can edit it with hex editor but some texts don't have enough space for me to edit it. Like I want to edit a text called "Items" to something like "Items 1234567890qwerty", is it possible to expand the text or something like that?

The second issue I'm having is the .spr4 files, I can't open it with the newest version of Amicitia, but I can with the older one (https://github.com/tge-was-taken/Amicitia/releases/tag/v0.3-alpha). But I can't save it and I got this error:

I just changed something in the source code, and so far I haven't encountered any issues with stuff I changed so it works, I guess. Hope someone can help me with eboot thingy tho.

Hi
I am also trying to edit some text in eboot.bin but I couldn't any edit I make on 010 editor the game stops working and I couldn't find a way to decrypt and edit the file

[olive hemlock]

you need to decrypt it with fagdec

[split bronze]

I was able to modify it directly by modifying the HEX codes without having to decode but it is a bit tedious.

[olive hemlock]

Yeah that's what I'm doing too

Please reupload the file🙏

[olive hemlock]

sec

Any other way to decrypt it? I don't have vita console

[olive hemlock]

i saw somewhere that you can use unmakeself thingy but i havent tried it myself

[pulsar olive]

I extracted elf file from eboot.bin with vita-unmake-fself, and what should I do now? Open it with hex editor still not showing any text

[olive hemlock]

those are the menu texts that you need

you need to keep the exact size tho, or the game just wont boot. I think you can write the text somewhere and then change the pointer but i also havent tried it

[pulsar olive]

Hmm 'kay

Thx for help

[pulsar olive]

It means I can't add more strings? Like Add to Adds

[sharp skiff]

I'm working with replacing strings on the P4G exe, so yes, you need to keep the exact size of the texts. If you want to replace the word "Add with "Adds" then you can do it using the "..." as a reference of the limit you have to make changes, just make sure it doesn't surpass thoses dots. Ex: "Add content....." to "Adds content..."

[pulsar olive]

How about strings like this? I can't event add one letter

[sharp skiff]

The NULL symbols are the points that separate each string, you can try writing over thoses without surpasing them (also you maybe want to try another hex editor like HxD or 010 editor, HxD is more comfortable for me)

[olive hemlock]

yea, but you can try redirect its pointers

thats how i translate those strings on p4g pc, not sure if it works on this game

[sharp skiff]

What I had to do to replace the english field names from P4G was make abbreviations of the words I was trying to use, because the space available to write what you want sometimes is not enough. I'm interested on knowing how you make redirections since that would be useful for me instead of just browsing on the EXE and trying to make the words fit

[olive hemlock]

u can use this if u want

starting at line 324 is when i change the pointers of the strings that need more space

just dont change anything ending with "_2" or "_redir:

[pseudo lantern]

but if there's a string that i havent redirect its pointer, download ghidra and the p4g project file

Analysed P4G 64-Bit exe for Ghidra 11.2 (auto analysis plus whatever stuff I happen to have labeled at this point)

then search for the string that you need to redirect, and then click on its xref

you will see its pointer

what i usually do is write the longer string on other languages string like German

and then i just type the starting address of the string i want the pointer to redirect to

[sharp skiff]

Oh thanks a lot! It definitely would help. So what I'm understanding here is: You first make the change for the text you want (EX: Capsule Machine being something like Máquina de Cápsulas on spanish), and then you make the same but with a _2 so Inaba Exe Patcher would take whatever you specify on that field as a continuation of the word to have more space for the string?

[sharp skiff]

Oh yeah, it definitely works like that! Before I had to call the Men's Bathroom the "Baño Mascul." and now it displays correctly as "Baño de Hombres"

Gonna make a separate thread and tag you there for another question I have since I wanna do another change with other string of the game, but I don't wanna differ for the topic of this thread

This "Fin" text also on eboot.bin?
