DS-Frotz is the port of Stefan Jokisch and David Griffith's Frotz, based on the GBA version from Jonas Minnberg.

The homebrew comes with a number of interactive fiction games/stories and the source code is included in the package.

Features

  • A multi-game main menu.
  • A multi-interface inputs: grafiti or keyboard (no voice recogition).
  • Text-completion functionnality.
  • Includes a lot of games.
  • Add and play your own games.

Installation

Download and extract file.

DLDI patch .nds file and copy all files to the root directory of the card.

It can play the majority of Inform files in z3, z5 or z8 format (up to V6 Inform format, with some bugs included).

User guide

All games have the same interface (stories are displayed on the top screen and text inputs on the bottom sreen), and can be played exactly the same way.

Input text

  • There are two ways to type words with the stylus of your Nintendo DS.
    • By default, you can directly draw the letters on the screen, according to the PA-Grafiti alphabet.
    • Second way is to use the mini keyboard or the numerical keyboard.

Icons

  • To avoid typing always the same things, the most used orders can be called via the icons.
  • Each icon has two or three states, for example:
    • The hand means GET, DROP and GIVE.
    • The N button means GO NORTH and GO UP.
  • Just pick an icon twice or more to select the good order.

Vocabulary

  • A sentence in these games is defined by a verb + a noun, such as OPEN DOOR, GO NORTH, etc.
  • Some sentences can have only one word, e.g. INVENTORY (to see what you're carrying) or SCORE (to see your score).
  • Each game has its own vocabulary, but a lot a verbs are common to all the games.
  • In many cases, you don't have to write the entire word, only the first letters are necessary. For example:
    • G HELM is esquivalent to GET HELMET.
    • CLIM DRAWB is equivalent to CLIMB DRAWBRIDGE.

List of the most common words:

GO - ENTER - CLIMB - SWIM - HELP
LOOK - EXAMINE - GET - DROP
THROW - ​CAST - WEAR - REMOVE
OPEN - CLOSE - LOCK - UNLOCK
BREAK - CUT - CHOP - SAY - KILL

Word completion

  • Draw a slash / in the middle of the word, the game engine will try to complete it with the latest words that have been printed on the screen.
  • You can draw this slash until you find the good word to continue.

Example:

​You are in the kitchen, you see a can wooden bench, 
a bootle of wine, and a cute babe...

>CLIMB ON B      - draw a slash here completes to:
>CLIMB ON BABE   - draw another slash here completes to:
>CLIMB ON BOTTLE - draw another slash here completes to:
>CLIMB ON BENCH  - that's fine.
 

Shortcuts:

N S E W - Equivalent to GO NORTH, GO SOUTH, GO EAST and GO WEST.
NE NW SE SW - In Level9 and Frotz games, this letters are equivalent to NORTH-EAST, NORTH-WEST, etc.
H - HELP.
I - INVENTORY.
G - GET (or AGAIN for Inform/Frotz games).
L - LOOK.
SV - SAVE.
LD - LOAD.
R - RESTORE.
