11  Plugins

Plugins are programs that Rockbox can load and run. Only one plugin can be loaded at a time. Plugins have exclusive control over the user interface. This means you cannot switch back and forth between a plugin and Rockbox. When a plugin is loaded, you need to exit it to return to the Rockbox interface. Most plugins will not interfere with music playback but some of them will stop playback while running. Plugins have the file extension .rock. Most of them can be started from Browse Plugins in the Main Menu.

Viewer plugins get started automatically by opening an associated file (i.e. text files, chip8 games), or from the Open with option on the Context Menu.

The goal of the game is to beat each level as quickly as possible by clearing the board of all bubbles. Bubbles are removed from the board when a cluster of three of more of the same type is formed. The game is over when any bubbles on the board extend below the bottom line. To make things more difficult, the entire board is shifted down every time a certain number of shots have been fired. Points are awarded depending on how quickly the level was completed.

11.1.4  Chessbox


PIC

Figure 11.4.: Chessbox

Chessbox is a one-person chess game with computer artificial intelligence. The chess engine is a port of GNU Chess 2 by John Stanback.

It also works as a PGN file viewer. Instead of executing the game from the plugin menu, look for any file with .pgn extension in the file browser and execute it. Chessbox will show the list of matches included in the file and allow you to select the one you want to watch. After that, you can scroll back and forth through the moves of the game. If the menu is invoked while in the viewer, the user is allowed to select a new match from the same file or quit the game.

“Force play” while the computer is thinking will cause it to make its move immediately. If done while it’s your turn, the computer will move for you and flip the board so that you are playing from the other side. If you want, you can force play an entire game and watch the artificial intelligence fight against itself.

When you quit the game the current state will be saved and restored when you resume the game. The menu also allows the user to reload the last game saved, save the current position and start a new game without having to quit the game.

Figure 11.6.: Doom

This is the famous Doom game.

Getting started

For the game to run you need .wad game files located in /.rockbox/doom/ on your player. Create the directory and save the following files there:

rockdoom.wad.
The Rockbox .wad, based on prboom.wad from prboom-2.2.6
Your wad files.
Copy all Doom wads you wish to play into that directory.

The needed files can be found at PluginDoom

To play addon wads create the addons directory within the doom directory. Place wad files in this directory. Currently doom only supports a maximum number of 10 addons.

A free alternative for Doom 2 is FreeDoom (http://freedoom.sourceforge.net). This can be used in place of doom2.wad, or it may be used as an addon in Doom, by placing it in the addons directory.

11.1.9  Goban


PIC

Figure 11.8.: Goban

Goban is a a plugin for playing, viewing and recording games of Go (also known as Weiqi, Baduk, Igo and Goe). It uses standard Smart Game Format (SGF) files for saving and loading games. You can find a short introduction to Go at http://senseis.xmp.net/?WhatIsGo and more information about SGF files can be read at http://senseis.xmp.net/?SmartGameFormat or the SGF specification at http://www.red-bean.com/sgf/.

This plugin can load all modern SGF files (file format 3 or 4) with few problems. It attempts to preserve SGF properties which it doesn’t understand, and most common SGF properties are handled fully. It is possible to view (and edit if you like) Kogo’s Joseki Dictionary (http://waterfire.us/joseki.htm) with this plugin, although the load and save times can be on the order of a minute or two on particularly slow devices. Large SGF files may stop audio playback for the duration of the plugin’s run in order to free up more memory and some very large SGF files will not even load on devices with little available memory.

Note: The plugin does NOT support SGF files with multiple games in one file. These are rare, but if you have one don’t even try it (the file will most likely be corrupted if you save over it). You have been warned.

The file /sgf/gbn_def.sgf is used by the plugin to store any unsaved changes in the most recently loaded game. This means that if you forget to save your changes, you should load /sgf/gbn_def.sgf immediately to offload the changes to another file. If you load another file first then your changes will be lost permanently. The /sgf/gbn_def.sgf file is also the file loaded if another is not selected.

The information panel which displays the current move number may also contain these markers:

+

11.1.26  Solitaire

Figure 11.23.: Klondike solitaire

This is the classic Klondike solitaire game for Rockbox. This is probably the best-known solitaire in the world. Many people do not even realize that other games exist. Though the name may not be familiar, the game itself certainly is. This is due in no small part to Microsoft’s inclusion of the the game in every version of Windows. Though popular, the odds of winning are rather low, perhaps one in thirty hands.

11.1.29  Sudoku


PIC

Figure 11.26.: Sudoku

Sudoku in Rockbox can act as both a plugin and a viewer. When starting Sudoku from the Browse Plugins menu, a random game will be generated automatically, and an estimate of its difficulty (very easy, easy, medium, hard or fiendish) will be displayed on the screen. New games can be generated from the Generate menu option. When “playing” an existing Sudoku game file from Rockbox’ file browser the plugin is invoked as viewer. The selected Sudoku will get loaded and you can start solving it. The sudoku games need to be stored as text files with the extension .ss as single file per game.

You can create and save your own grids under the New menu option. Enter the menu (as described in the key table below) when you have finished and enter the full path to save to including the .ss extension (e.g. /sudoku/new.ss).

The scratchpad

When you play Sudoku on paper most people like to mark numbers in cells that are possible candidates for the cells. This can be done with the scratchpad, shown as separate column. Change the number under the cursor to the number you want to put on the scratchpad and press the scratchpad button, the number will then be added. If the number was already on the scratchpad it will get removed again. The column is stored separately for every cell on the board. The stored values can be displayed inline as small dots by enabling the Show Markings settings.

Note: The scratchpad is not saved when saving the game.

Figure 11.27.: Wormlet game

Wormlet is a multi-worm game on a multi-threaded multi-functional Rockbox console. You navigate a hungry little worm. Help your worm to find food and to avoid poisoned argh-tiles. The goal is to turn your tiny worm into a big worm for as long as possible.

The game

Use the control keys of your worm to navigate around obstacles and find food. Worms do not stop moving except when dead. Dead worms are no fun. Be careful as your worm will try to eat anything that you steer it across. It won’t distinguish whether it is edible or not.

Food.
The small square hollow pieces are food. Move the worm over a food tile to eat it. After eating the worm grows. Each time a piece of food has been eaten a new piece of food will pop up somewhere. Unfortunately for each new piece of food that appears two new “argh” pieces will appear, too.
Argh.
An “argh” is a black square poisoned piece - slightly bigger than food - that makes a worm say “Argh!” when run into. A worm that eats an “argh” is dead. Thus eating an “argh” must be avoided under any circumstances. “Arghs” have the annoying tendency to accumulate.
Worms.
Thou shall not eat worms. Neither other worms nor thyself. Eating worms is blasphemous cannibalism, not healthy and causes instant death. And it doesn’t help anyway: the other worm isn’t hurt by the bite. It will go on creeping happily and eat all the food you left on the table.
Walls.
Don’t crash into the walls. Walls are not edible. Crashing a worm against a wall causes it a headache it doesn’t survive.
Game over.
The game is over when all worms are dead. The longest worm wins the game.
Pause the game.
Press Navi to pause the game. Press it again to resume the game.
Stop the game.
There are two ways to stop a running game.

The scoreboard

On the right side of the game field is the score board. For each worm it displays its status and its length. The top most entry displays the state of worm 1, the second worm 2 and the third worm 3. When a worm dies its entry on the score board turns black.

Len:
Here the current length of the worm is displayed. When a worm is eating food it grows by one pixel for each step it moves.
Hungry:
That’s the normal state of a worm. Worms are always hungry and want to eat. It is good to have a hungry worm since it means that your worm is alive. But it is better to get your worm growing.
Growing:
When a worm has eaten a piece of food it starts growing. For each step it moves over food it can grow by one pixel. One piece of food lasts for 7 steps. After your worm has moved 7 steps the food is used up. If another piece of food is eaten while growing it will increase the size of the worm for another 7 steps.
Crashed:
This indicates that a worm has crashed against a wall.
Argh:
If the score board entry displays “Argh!” it means the worm is dead because it tried to eat an “argh”. Until we can make the worm say “Argh!” it is your job to say “Argh!” aloud.
Wormed:
The worm tried to eat another worm or even itself. That’s why it is dead now. Making traps for other players with a worm is a good way to get them out of the game.

11.3.1  Shortcuts

The Shortcuts Plugin allows you to jump to places within the file browser without having to navigate there manually. The plugin works with .link files. A .link file is just a text file with every line containing the name of the file or the directory you want to quickly jump to. All names should be full absolute names, i.e. they should start with a /. Directory names should also end with a /.

How to create .link files

You can use your favourite text editor to create a .link file on the PC an then copy the file to the player. Or you can use the context menu on either a file or a directory in the file browser tree, and use the “Add to shortcuts” menu option. This will append a line with the full name of the file or the directory to the shortcuts.link file in the root directory of the player. (The file will be created if it does not exist yet.) You can later rename the automatically created shortcuts.link file or move it to another directory if you wish. Subsequent calls of the context menu will create it again.

How to use .link files, i.e. jump to desired places

To use a .link file just “play” it from the file browser. This will show you a list with the entries in the file. Selecting one of them will then exit the plugin and leave you within the directory selected, or with the file selected in the file browser. You can then play the file or do with it whatever you want. The file will not be “played” automatically.

If the .link file contains only one entry no list will be shown, you will directly jump to that location. The file shortcuts.link in the root directory is an exception. After “playing” it, the list will be shown even if the file contains just one entry.

If the list you are seeing is from shortcuts.link in the root directory, you can delete the selected entry by pressing A-B. Deleting entries from other .link files is not possible.

Advanced Usage

Placing the line “#Display last path segments=n” (where n is a number) in the beginning of a .link file will leave just the last n segments of the entries when they are shown. For example, if n is chosen to be 1, then the entry /MyMusic/collection/song.mp3 will be shown as song.mp3. This allows you to hide common path prefixes.

You can also provide a custom display name for each entry individually. To do so, append a tabulator character after the entry’s path followed by your custom name. That name will then be used for showing the entry. For example:

  /MyMusic/collection/song.mp3<TAB>My favourite song!

11.3.2  Chip-8 Emulator

Chip8 is a kind of assembly language for a long-gone architecture. This plugin runs games written using the chip8 instructions. To start a game open a .ch8 file in the File Browser

There are lots of tiny Chip8 games (usually only about 256 bytes to a couple of KB) which were made popular by the HP48 calculator’s emulator for them. The original Chip8 had 64×32 pixel graphics, and the new superchip emulator supports 128×64 graphics.

The only problem is that they are based on a 4×4 keyboard, but since most games do not use all of the buttons, this can easily be worked around.

To do this, one may put a .c8k file with the same name as the original program which contains new key mappings (for BLINKY.ch8, one writes a BLINKY.c8k file). That .c8k file contains 16 characters describing the mapping from the Chip8 keyboard to the default key mapping (that way, several Chip8 keys can be pressed using only one Rockbox key). For example, a file containing the single line:

  0122458469ABCDEF

would correspond to the following non-default mappings:

3 2, 6 8, 7 4, 8 6.

The default keymappings are:


Chip8 Off 0 1 2 3 4 5 6 7 8 9 A B C D E F

11.3.3  Frotz

Frotz is a Z-Machine interpreter for playing Infocom’s interactive fiction games, and newer games using the same format. To start a game open a .z1 - .z8 file in the File Browser. Most modern games are in the .z5 or .z8 format but the older formats used by Infocom are supported.

Z-Machine games are text based and most depend heavily on typed commands. The virtual keyboard is used for text entry, both for typing entire lines and for typing single characters when the game requires single character input.

Sounds, pictures, colour and Unicode are not currently supported, but the interpreter informs the game of this and almost all games will adapt so that they are still playable. This port of Frotz attempts to be compliant with the Z-Machine Specification version 1.0.

11.3.5  Lua scripting language

To quote from the Lua website (http://www.lua.org), Lua is a “powerful, fast, lightweight, embeddable scripting language”. Select a .lua file in the File Browser to run it. For more information on programming in Lua, please see http://www.lua.org/manual/5.1/ and http://www.lua.org/pil/.

There are a few exceptions/additions to the Lua support in Rockbox:

No floating point support.
The number type in Lua is usually float, however in the Rockbox implementation it is integer.
Non-supported libraries.
The coroutine, debug and math libraries are not supported.
Partially-supported libraries.
The os and package libraries are only partially supported.
Additional libraries.
The bitlib library is integrated to support bitwise operators. See http://luaforge.net/projects/bitlib and http://lua-users.org/wiki/BitwiseOperators.

Documentation of the API is still a work in progress, and the API itself is not finalised. For the latest information, see PluginLua.

Note: Please note that if a script does not provide a way to exit, then the only way to exit will be to reset the player.

11.3.6  Midiplay

To get MIDI file playback, a patchset is required. This file contains the instruments required to synthesize the music. A sample patchset is available through the wiki at PluginMidiPlay, and needs to be extracted to the .rockbox directory in the root of your player. There should now be a /.rockbox/patchset/ directory, with the patchset directory containing several .pat files and two .cfg files. Just select a MIDI file with either the .mid or .midi extension in the file browser to start playback.

11.3.8  MP3 Encoder

This plugin encodes a .wav file to MP3 format. The supported input format is uncompressed, linear PCM with 16 bit per sample and a maximum of 2 channels. Allowed sample rates are 16, 22.05, 24, 32, 44.1 and 48 kHz. The user will be asked to select the desired output bitrate of the compressed MP3 file.

Select Bitrate
The following bitrates can be selected: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 kbps.

Remark: Bitrates above 160 kbps cannot be used in MPEG 2 Layer 3 bitstreams. The encoder plugin automatically limits the output bitrate to 160 kbps for input files with a sample rate of 16, 22.05 or 24 kHz. The same limitation is valid for mono files.

The output .mp3 file is written to the same path as the .wav file using the same filename. To use this plugin, open the Context Menu (see section 4.1.2) on a .wav file and select Open With…mp3_encoder.

Note: The encoder will choose the appropriate bitstream format from the sample rate of the input file. The output bitstream format is MPEG 1 Layer 3 for 32, 44.1 and 48 kHz, and MPEG 2 Layer 3 for 16, 22.05 and 24 kHz. MPEG 2.5 Layer 3 is not supported.

11.3.15  VBRfix

This function scans a VBR (Variable Bitrate) MP3 file and updates/creates the Xing VBR header. The Xing header contains information about the VBR stream used to calculate average bit rate, time information and to more accurately fwd/rew in the stream. This function is especially useful when the playback of a file skips, fwd/rew does not work correctly or the time display is incorrect. To use this plugin, open the Context Menu (see section 4.1.2) upon a .mp3 file and select Open With… vbrfix.

Note: VBRfix can only run when music is turned off (since it uses the same memory as the player) and can take a while to complete if run on big files.

11.3.16  ZXBox


PIC

Figure 11.45.: ZXBox

ZXBox is a port of the “Spectemu” ZX Spectrum 48k emulator for Rockbox (Zproject’s homepage). To start a game open a tape file or snapshot saved as .tap, .tzx, .z80 or .sna in the file browser.

Note: As ZXBox is a 48k emulator only loading of 48k z80 snapshots is possible.

Default keys

The emulator is set up for 5 different buttons: Up, Down, Left, Right and Jump/Fire. Each one of these can be mapped to one key of the Spectrum Keyboard or they can be used like a “Kempston” joystick. Per default the buttons, including an additional but fixed menu button, are assigned as follows:

Predefined Keymap
Select one of the predefined keymaps. For example 2w90z means: map ZXBox’s Up to 2, Down to w, Left to 9, Right to 0 and Jump/Fire to z. This example keymap is used in the “Chuckie Egg” game.
Custom Keymap
This menu allows you to map one of the Spectrum keys accessible through the plugin’s virtual keyboard to each one of the buttons.
Quit.
Quits the emulator..

Hacking graphics

Due to ZXBox’s simple (but fast) scaling to the screen by dropping lines and columns some games can become unplayable. It is possible to hack graphics to make them better visible with the help of an utility such as the “Spectrum Graphics Editor”. Useful tools can be found at the “World of Spectrum” site (http://www.worldofspectrum.org/utilities.html).

11.4  Applications

11.4.1  Battery Benchmark

The Battery Benchmark plugin enables you to test your battery’s performance whilst using your player normally. Results can be submitted to the BatteryRuntime wiki page.

How it works

Once loaded, Battery Benchmark runs in the background recording various information about your battery to memory. A new point is written to memory every minute. Every time the disk is accessed for any reason (such as refilling the audio buffer, opening a directory or entering USB mode etc.) then the information in memory is written to disk. Once the memory becomes full (after many hours), then the data are written to disk anyway. This is done so that the data are not biased by excessive additional disk accesses. The file is written to the root directory of your player and is called battery_bench.txt. The plugin will continue to log info until:

Benchmarks can be resumed if you accidentally load a plugin, or turn off your player, so long as the log file battery_bench.txt is not deleted.

Information explained

At the top of the battery_bench.txt file is various information on how to use the plugin, followed by the data themselves.

Time
This column reports the total time of operation of the player. It is not the time that you started the plug-in. If you have your player on for 5 minutes and then start the plugin, it will start measuring from 5 minutes.
Seconds
The same as Time, except measured in seconds.
Level
The percent level of the battery estimated by Rockbox, and not the actual battery level. The actual battery level can be seen from the Voltage column
Time Left
This shows the time remaining until the battery is empty, again as estimated by Rockbox.
Voltage
The battery voltage in mV at the moment the measurement was taken.
C
This stands for Charger. An “A” in that column shows if the power adapter was attached to the unit at the time of the measurement.
U
USB powered. Only for targets that support this. A “U” will indicate if the unit was using the USB port for power at the time of the measurement.

Usage

The log file can be used to tell you how long the battery lasted (with some limitations, see below), but it is most useful for graphing discharge curves in order to improve Rockbox’s estimation of battery level and time remaining. The battery log (battery_bench.txt) is in CSV format (comma separated variables) and thus can be easily imported into a spreadsheet or similar program.

Limitations

As Battery Benchmark needs to write the data held in memory to disk in order to save them, it is possible that should Rockbox shut down due to low battery then there will not be enough power remaining to write the data to disk. Therefore all measurements since the previous save will be lost.

11.4.2  Calculator

11.4.4  Disk Tidy

Disk Tidy deletes junk files commonly left behind by Windows, Linux and OS X after connecting your player over USB. Select the files you want to delete in the “Files to Clean” menu and select “Start Cleaning” to begin the process. The settings are stored in the plain text file .rockbox/rocks/apps/disktidy.config that is user-modifiable to allow custom entries to be added.

The asterisk character (“*”) can be used as a wild-card which will match any string; however only the first asterisk will be recognised as a wild-card with any additional uses being taken as literal.

Warning: Be careful when you use custom entries as you could accidentally delete important files.

.lrc
2.
.lrc8
3.
.snc
4.
.txt

Each line should resemble one of the following:

[time tag]line  
[time tag]...[time tag]line  
[time tag]<word time tag>word<word time tag>...<word time tag>

The time tag must be in the form [mm:ss], [mm:ss.xx], or [mm:ss.xxx] where mm is minutes, ss is seconds, xx is tenth of milliseconds, and xxx is milliseconds. Any other tags and lines without time tags are ignored.

Location of lyrics files

The plugin checks the following directories for lyrics files. If no lyrics file is found and the audio file is a .mp3, it also checks for SYLT and USLT tags in the id3v2 tags.

1.
The directory containing the audio file and its parent directories.
2.
For each of the above directories, the plugin searches for a subdirectory named “Lyrics”.
3.
Finally, the plugin will search as above, but within a directory called “/Lyrics”. The name of this directory can be customized, see below.

If the audio file currently playing is /Music/Artist/Album/Title.mp3, then the following files will be searched for, in this order. .ext is one of the supported extensions from the list above, and will be searched for in the same order as in that list.

11.4.12  Resistor Calculator


PIC

Figure 11.48.: Resistor calculator

The resistor calculator is a plugin that works in 3 modes:

Colour to Resistance

In Colour to Resistance mode, use the menus to select the colours of the bands of a resistor which you would like to know the resistance of.

Resistance to Colour

In Resistance to Colour mode, use the menus to select the unit that you would like to use (choose from Ohms, Kiloohms, Megaohms), and use the on-screen keyboard to input the value of the resistor that you would like to know the colour code of. The colour codes are presented textually.

LED resistance

LED resistance calculator is used to determine the resistor necessary to light an LED safely at a given voltage. First, select the voltage that the LED will use (the first option is the most common and a safe bet), and the current that it will draw (likewise with the first option). Then, use the onscreen keyboard to type in the supply voltage and, if selected, the custom forward current. This function produces safe estimates, but use your own judgement when using these output values. Power rating and displayed resistance are rounded up to the nearest common value.
