Last week I started working on creating multilanguage dat file for the Teen Agent. Currently, only the English version is supported, and Polish, Czech and Russian versions needs to be added.
The task is to extract language specific data, strings from the executables, put them in the create_teenagent utility and finally generate the .dat file for the use of engine. The extraction tools for the game were already in hand, although I had to write custom python scripts to create cpp code from them. The strings that needed to be extracted are the following:
- Names and descriptions of inventory items
- Dialogs
- Messages
- Character’s thoughts
- Credits
- Names and descriptions of scene objects
Most of them were not difficult extract and put in the code, except for the scene objects. I started with the Russian version, and the problem was that some string could not fit in the original positions, so they had to be copied to the free space of the data segment. That includes the pointers to those objects. So this caused a little issue, and I am in process of writing it properly.
In parallel, I was also looking at the Polish (CD) version. This version brought more issues, which I am yet to solve. The problem is that Polish executable is larger than the English, and has two more scene objects. The sizes of texts are also generally bigger, so I would not be able to fit them into the dat file. I am thinking of putting them after the data segment and dialogs. However, that would require also changing in a couple of places in the engine code, since it relies on the data segment. This means that save system also needs to be adapted for this, as the engine is currently writing the save section part of the data segment. I’ve already tried this idea and separated the credits section the data segment, and put it separately at the end. This allowed to display the Polish text in the credits section:
Similarly, I’ve experimented with the dialogs, and they also started showing up properly:
However, there is also a Dialog stack, which is modified at runtime by the game, so I probably will need to put as a resource in different segment as well.
