ROM Hack Gyakuten Saiban 1-3 Translation

[MarkDarkness]

No, this patch uses the same script that was used in the DS release.

The translation is identical to the NDS version. I didn't read anything specific about a country in the scripts, but yes, there is a lot of American slang in them.

Oh... such a shame. Maybe in the future.

In the meanwhile, I had a look on the first game (Gyakuten Saiban 1).

The first thing to do is to place a VWF (variable width font) routine inside the ROM, so that it can display english text. After a lot of experimentation, I was able to roughly fit broco's VWF routine (used in GS3) in the ROM, with a few alterations. It is still far from perfect though.

Anyway, I decided to make a small demo of the first game:

Um... Mr. @h3rmit Can you hack the text to make it 3 lines? Like in the Gyakuten Kenji 2 Fan Translation?

You can try Tapatalk if you're using Android/iOS. It's way easier to browse than on the mobile website, and it's much faster on older phones too.

OK i'll try that...

You can contact me via PM if you have any questions about it, so we could stop the off-topic chat in this thread.

It seems I need to have another look in case 2 and fix a few things that I may have missed.

Can you tell me in which parts of the case did the above bugs happen? It will be easier to locate them that way.

• The missing textbox and the wrong color are easy to fix.
• The missing hand in the multiple choice screen is just a lack of space in the memory of the game. There is too much text in the choices, and the hand is overwritten. The only way to fix it is to shorten the text.
• The crash is a critical issue, I'll need to have a look at it.

I guess that would be impossible (or, at least, very very hard)...GBA screen size is smaller than a DS screen, and its mechanics are different.

The crash occurs at the first trial after Atmey reveals that he is Demasque... But please focus on the first game... Btw...
@h3rmit , can you make this into a new thread? Also make the first game to 3 lines before its too late?

 

[Objection!]

I did not finish case 2 because of the bugs... But here are the bugs of case 3 so far:

Japanese
No color
Infinite loop

 

[h3rmit]

Gyakuten Saiban 3 Patch 015.2

This is a bugfix release.

• Translated the sports paper image
  
  
• Fixed an infinite loop in case 3-2
  
  
• Fixed a few text colors in case 3-2

I didn't have the time to have a look at case 2, it will probably need a re-check of parts 2-2 and 2-3. I haven't really touched the scripts of these parts, since they were already translated by cocomonk22. I just ensured that they were inserted properly in the ROM.

Meanwhile, I have made some progress in Gyakuten Saiban 1.

I have translated several voices, evidence and other graphics. I also fixed a few issues with the scripts. There is still a problem with the english font routine when displaying fullscreen multiple choices, I am trying to fix it. Case 1-1 is not yet fully translated, but it is playable. So I will release another demo, much better from the previous one.

Gyakuten Saiban 1 Patch 001 DEMO

@Objection! Sorry, I can't make the text occupy 3 lines. There is not enough space in the screen, but even if there were, it would require huge changes in the code of the game, which I don't possess the required ASM knowledge to make. Also, I see no need to start a new thread at the moment.

Mean while in the GS1:

At what point does this crash appear?

Is that after the end of the first case? If yes, it is normal. I haven't yet touched the second case.

Start of the first case... :/
Btw... After you translate the second game... Will you fix the bugs on the 3rd game?

 

[h3rmit]

Is there a dialog or something that appears before the crash? Does the intro of case 1 play normally? Or does it happen exactly when you select case 1 in the case selection menu?

I haven't yet fixed the crash in the second case of GS3, but I will look at it tomorrow.

It happends before the intro.
