Hacking [PSP] La Pucelle Ragnarok Translation

[ChepChep]

Updated... I have fixed all the typos that Cyan has reported... I will include them in the next patch.

 

[Gaming4Ever]

THX a Bunch ChepChep really loving all the Updates on this.....Been slowly advancing and loving every minute of it hopefully we get some more Progress on PKP

I don't know where to ask this but how to get the good ending for the side story/alternate story?

Chep posted a small as-non-spoiler-as-possible walkthrough of what you need to do to get the good endings in all four chapters, to get the good ending overall.

Why is it there's only audio for the first dialog in most conversations in the game?
and translate the system language? the home menu is still in japanese

 

[Cyan]

When playing in japanese, all the text fit in a single "dialog box", so audio is span over a single box.
If you press O it skip the box and also the audio to play the next one.
It would need more hack to prevent the audio cutting when pressing O if there are more text box for the same conversation.

I don't know if the home menu is part of the game, it's maybe dependent to the PSP firmware detecting it's a japanese game and using japanese menu.
Same for the Save menu.

If there's a bit determining the region, maybe it could be patched?

 

[ChepChep]

I have tried figuring out O button issue and it is beyond my ability at this point. Also the home menu as save screen is the firmware detecting the the japanese game and displaying the correct language. I have not figure out how to get it in english but it should be possible to trick the firmware to display english.

I'm still trying to beat the last chapter...
I don't have any character left except the fake/back to Lv1 princess. (I don't know where that character comes from, a bug on the bonus chapter?)
The ennemies are really strong and I'm killed in two turns, so I'm making a looot of leveling with captured enemies (again ;__; Why my trained characters are not with me?)

about the save menu, it seems if you patch the language detection, only the "Load/Back/Enter/Load Completed/Saved/Exit without saving?" will be translated.
All the rest of the text related to the story progress needs to be translated manually, so it should be somewhere in the game, do you know where it's located?
Like "Level" "Chapter", chapter name, etc.

Stormyu can help you with setting the Home Menu and Save Menu detection to english.

Cyan,

Looking at the thread I think I have an idea of what needs to be done to translate to English. I am learning more about how to do the ASM and use the PPSSPP debugger and RAM dumper. I will look into trying to fix this for LPR and PKP.

-ChepChep

 

[Cyan]

Stormyu explained to me that I need to use ppsspp debugger, search for the Function zz_sceUtilitySavedataInitStart() (at the bottom of the function list)
From there, we can follow the ASM, but I don't understand ASM so I only guess from here.

I think there's two possibilities:
- Hack the function itself to always return english. (require ASM programming, which I don't know)
or
- Find the memory containing the arguments passed to the function and edit the language in the DialogCommon.


He will show me next Monday how to really do it.
But you know better how to hack the game than me, I just wanted to learn new things

 

[ChepChep]

I have not done much ASM hacks or at least write new code... Let me know tricks he may show...

 

[JamRules]

If you want the home menu in English you might want to look into sceImposeSetLanguageMode as well as sceUtilitySavedataInitStart

http://psp.jim.sh/pspsdk-doc/pspimpose__driver_8h.html#a1858adc7ea1ccad5ff3b356ed5b1c3c0

if I remember correctly 0=Japanese, 1=English

Edit: screenshot for sceUtilitySavedataInitStart if it helps. 0x4 from register a0 should be 0x01, should be able to use a breakpoint to find the save

 

[ChepChep]

I have the home menu in english in the unreleased patch. Someone a few months ago help me with finding that one.

 

[Cyan]

From the function name, how to do you find the address you need to edit?

You have:
zz_sceUtilitySavedataInitStart > 0x08994558 > Register a0
Why a0 ? how do you know this is the one with the "data" struct?

this is what I found:

Spoiler: a0

so I replace 0x08ACB650 to 0x01 ?

But this is the RAM address, not a file position I need to edit in the ISO, so there's probably something I need to program to force this value to 1?
Or find the place in the ISO where this value appear?

I can edit the RAM address in ppsspp, but it's automatically setting the interface to the language defined in the emulator's option, so I don't see any differences. (or it's not the correct place to edit)

 

[JamRules]

The function is a syscall so the input register should always be the same.
And yes replacing 0x08ACB650 is correct.

To change it you need to add a write breakpoint for 0x08ACB650, size 4.
There should be an sw/sb instruction (for example Sol Trigger has this "sw zero, 0x4(a0)" )
(Sorry, don't have a copy of the game so can't help with specifics)

Once you've found the instruction you need to save the value as 1, may be difficult depending on the asm.
You'll then need to find it in eboot.bin and hex-edit it.

 

[Cyan]

Thanks for your help
This is the first time I try an emulator's debugger, so I'm discovering possibilities and menus.

I added the break point 0x08ACB650, size 4, read/write, but it doesn't hit it when I go to the save menu.

Strange, It should be hit. Unless the value is loaded via IORead but I would think that unlikely.

Maybe use Emulation/Reset since it may be saved ready. You should at least be able to observe the value changing

 

[Cyan]

ah yes, when reseting it's hit two times.
I see that this value is accessed only at launch (the game is checking Memory card...), not later while accessing save data.

That's interesting to do.

You may have to change more than one location, each dialog will likely have it's own value.
So there may be separate values for each load and save.

when the break point hits zz_sceUtilitySavedataInitStart click RA under goto (or use step)
to find where the call is made from. Forget to mention earlier it's quite common for there to be separate dialog values for each call.

I suppose you could play through and list all the a0 values used

 

[Cyan]

I found the ASM writing to 0x08ACB650

Spoiler

Can I add 4 bytes into eboot.bin or is there a checksum?
I think I need to convert

Address      ASM                               Action                                    Hex Value of ASM

088A4A70    lui   v0,0x8AD              ; set 0x08AD0000 into v0                         // 0xAD08023C

088A4A74    sw    zero,-0x49B0(v0)      ; write zero to address v0-0x49BA (08ACB650)	 // 0x50B640AC

to:

insert4bytes li    0a,0x01              ; set 01 into a0                                // 0x01000424

088A4A70     lui   v0,0x8AD             ; set 0x08AD0000 into v0                        // 0xAD08023C

088A4A74     sw    a0,-0x49B0(v0)       ; write a0 to address v0-0x49BA (08ACB650)	// 0x50B644AC

This is my first time reading/writing ASM.


But when I edit 0x50B644AC to 0x01 in PPSSPP RAM, I can't access save menu anymore, so it's maybe not the correct address to edit.
