📋 About This Mod

Learn a language while you play. This mod shows TWO subtitle languages at once: your normal language on top, and a second language on the line below; for every piece of spoken dialogue and every in-game document, memo, and item description.

DualSub for Grand Theft Auto III

The Definitive Edition

======================================================================

Two subtitle languages on screen at once. The one you play in on top,

the one you are learning underneath, in grey.

You weren't followed? Good.

¿No te siguieron? Bien.

You already know this story. That is the point: you are never lost,

so you can spend your attention on the second line instead.

WHAT YOU NEED

----------------------------------------------------------------------

Python 3. Nothing else. No other program, no downloads, nothing to

unpack into the game folder.

Windows does not come with Python. Get it from python.org, and on the

first screen of the installer tick "Add python.exe to PATH".

HOW TO PUT IT ON

----------------------------------------------------------------------

1. Put dualsub_installer.py anywhere you like. Next to the game is

convenient but it does not have to be.

2. Double-click it. If that opens an editor instead, right-click it

and choose "Open with" -> Python.

3. It will look for the game. If it cannot find it, paste in the

folder that holds PlayGTA3.exe.

4. Answer three questions:

which language you PLAY in    the one you already follow

which language you LEARN      the one that goes underneath

which lines get both          speech, pager, mission text,

5. It writes one file and tells you it is done. That takes about a

6. Start the game and set its own Language option to the language you

said you play in. That is what decides which of the two is on top.

THE THIRTEEN LANGUAGES

----------------------------------------------------------------------

English            Polish            Japanese

German            Portuguese (BR)    Korean

Spanish            Russian            Chinese (Simplified)

Spanish (LatAm)    French            Chinese (Traditional)

All of them are already inside your copy of the game. Nothing is

downloaded and nothing is bundled with this. Any one of them can go

with any other -- all 156 combinations work, including Japanese,

Korean and both Chinese as the language you are learning, because the

installer points the game's own face for that language at the second

THE FOUR KINDS OF LINE

----------------------------------------------------------------------

the spoken lines          what characters say, in a mission or a

the phone and the pager  the pager messages

the mission text          your objectives, the warnings, and the

tutorial help

the menus and the rest    menus, statistics, credits, car and place

The first three are on. The menus are off, because a doubled menu is

mostly in the way. Turn any of them on or off in step 3.

Each one can also be set to show the language you are learning ON ITS

OWN, with no English above it. That is for when you are further along

and want to be thrown in.

A note on this game in particular. Grand Theft Auto III's text is one

flat list with nothing in it that says "this line is spoken" -- Vice

City added that a year later. So the split above is made from the way

Rockstar wrote the keys and the colour codes, and it is very good but

it is not perfect: a handful of on-screen messages ride along with the

speech, and some of the tutorial help sits with the menus. Nothing is

ever mistranslated by it; a line only ever ends up under the wrong

TAKING IT OFF

----------------------------------------------------------------------

Run it again and press R.

Nothing the game came with is ever changed, moved or renamed. The

whole install is one file in a folder called ~mods that the game did

not have before, so removing it is deleting that file. If something

else has replaced it since, it is left alone and you are told.

IF SOMETHING GOES WRONG

----------------------------------------------------------------------

Windows will not let it write

Close the game and the Rockstar launcher. If the game is under

Program Files, open the command window as administrator and run it

from there.

The second line is not there

Check the game's own Language option is set to the language you
