Das tttool hat jetzt eine deutsche Webseite für Anwender: http://tttool.entropia.de/
The goal of this project is to understand the file and paper format for the Ravensburger TipToi pen. The ultimate goal is that everyone can create their own books, with their own sounds.
The current status is that we understood most of the file format (see the GME file format specification). We provide a tool that allows you to dissect these files.
The tool can also be used to generate completely new files from scratch; see below for details.
If you want to learn more please have a look into our wiki (https://github.com/entropia/tip-toi-reveng/wiki).
Use the tool tttool
to investigate the gme files and build new ones. It
supports various subcommands:
GME creation commands:
assemble creates a gme file from the given source
OID code creation commands:
oid-table creates a PDF file with all codes in the yaml file
oid-codes creates PNG files for every OID in the yaml file.
oid-code creates PNG files for each given code(s)
GME analysis commands:
info Print general information about a GME file
export dumps the file in the human-readable yaml format
scripts prints the decoded scripts for each OID
script prints the decoded scripts for a specific OID
games prints the decoded games
lint checks for errors in the file or in this program
segments lists all known parts of the file, with description.
segment prints the decoded scripts for a specific OID
explain print a hexdump of a GME file with descriptions
holes lists all unknown parts of the file.
rewrite parses the file and reads it again (for debugging)
GME extraction commands:
media dumps all audio samples
binaries dumps all binaries
Simulation commands:
play interactively play a GME file
Run
./tttool --help
to learn about global options (e.g. DPI settings), and
./tttool command --help
for the options of the individual command.
This program is written in Haskell and can be installed on Windows, MacOS or Linux.
For Windows users, we create zipfile containing tttool
, you can find them in
the releases section of
the github project.
Otherwise, installation from source is not difficult either:
-
If you have not done so yet, fetch the source code and change to the directory containing the code:
git clone https://github.com/entropia/tip-toi-reveng.git tttool cd tttool
-
Install the Haskell platform, see http://www.haskell.org/platform/ for details for your system. Users of Debian or Ubuntu simply run
apt-get install haskell-platform
-
Install the development packages for ncurses, i.e.
apt-get install libncurses5-dev
-
Install the Haskell dependencies. The Haskell platform comes with a tool called
cabal
, and you should run the two commandscabal update cabal install --only-dependencies
-
Now you can build the program using
cabal install --bindir=.
-
At this point,
tttool
should be ready to go. If you run./tttool
you should see the list of commands shown above.
If you have any problems, you can report an issue via GitHub.
Once you have installed tttool
, you can create your own .gme
files. The
process is as follows
-
Record the audio samples you want to include, as Ogg Vorbis files, mono, 22050Hz. I use
arecord -r 22050 foo.wav oggenc foo.wav rm foo.wav
-
Write a
my-book.yaml
file containing some general information, and especially the scripts (i.e. what to do) for each OIDs (i.e. the various fields of a book). You can use the example.yaml file as a starting point; it contains more information in its comments. -
Run
./tttool assemble my-book.yaml
, and make sure it reports no error, i.e. finishes silently. -
Copy the now generated
my-book.gme
to your TipToi pen and enjoy!
If you need to find out what OID code corresponds to what part of the book, you
can generate a debug gme using the debug.yaml
file, adjusting its
Product-Id
to your product’s id, building it with ./tttool assemble debug.yaml
and loading the resulting debug.gme
on your pen. It will then
read out the codes, as a sequence of english digits.
We are also collecting template files, where the OIDs are commented; these can
be found in the ./templates
directory. Please improve and contribute!
Again, please let us know if you have problems, but also tell us what fun things you did if you succeded.
If you have libttspico-utils
and vorbis-tools installed
, you can have tttool
generate audio files from text for you, which makes developing your yaml file
much easier. See text2speech.yaml for more information.
With the code in this repository, you can create GME files. This is even more fun if you can also create your own books! „Pronwan“ found out how that works, as you can see in this video demonstration. He also published 30 minute video tutorial (in German).
