The Sazanami-Mincho-Regular-*.fnt includes 7128 characters.
However, there are about 7500 character not included in the Sazanami-Mincho-Regular-*.fnt though it is included in the sazanami-mincho.ttf font (This font is a font that became an origin when the Sazanami-Mincho-Regular-*.bdf font is made).

Please look at “List.txt” file about the character not included in the Sazanami-Mincho-Regular-*.fnt.

The cause of this problem is in “fontForge”(http://fontforge.sourceforge.net)
used when the bdf file is made from the ttf file.

When the bdf file was made by using　”Otf2bdf”(http://www.math.nmsu.edu/~mleisher/Software/otf2bdf/) instead of “fontForge”, all characters included in the ttf file were able to be taken out.

However, when you make the Sazanami-Mincho-Regular-*.fnt by using Sazanami-mincho-Regular-*.bdf that applies the patch,
The interval between the line and the line opens from present Sazanami-Mincho-Regular-*.fnt a little.

Please report by using new Sazanami-Mincho-Regular-*.fnt(in new-Sazanami-Mincho-Regular-fonts.zip).

This font is part of the WenQuanYi Project at [1]. It’s in Chinese, but there’s an english page at [2]. This font is similar to the WenQuanYi Unibit font (FS#9059) and focuses mostly on ASCII and CJK, but I’m also posting this font for inclusion because this one has different point sizes, like for example the nimbus, Sazanami and ProFont fonts already included in Rockbox. With the different point sizes, especially lower point sizes, this font is great for small screens such as my iPod Nano.

I’m attaching some screenshots of this font under various point sizes and weights. I’ve also taken screenshots with the simulator to show how it would look like in Rockbox.

Additionally, this font is available from the original website at [3]. There is also an online README file at [4]. The source BDF files are available from the project’s SourceForge page at [5], and the BDF files I’m attaching come from the source package at [6].

According to the project[4], this font is a derivation of older free fonts and enhanced with bitmaps made by online users. As such, it is licensed under the GPLv2 with a font embedding exception[4]:

This font is part of the WenQuanYi Project at [1]. It’s in Chinese, but there’s an english page at [2].

I’m adding this font because:
1. Currently there is no good Chinese font for Rockbox.
2. The best Chinese font (unifont) has unevenly sized Chinese characters, while this font has uniformly sized Chinese characters.

The attachments contain screenshots of the simulator, to show how this font would look like on the iPod Nano. I’ve also attached a screenshot using the Unifont font to show the uneven sizes of Chinese characters, for comparison. I don’t know about other languages, but I’d think other CJK languages work better in this font as well, due to the merging of WenQuanYi Bitmap Song.

According to the project[3], this font is made by combining the GNU Unifont (GPL), WenQuanYi Bitmap Song (GPL) and Fixed-16×8 (Public Domain) fonts. The maintainer of GNU Unifont also acknowledges this fact at [4].

The font I’m attaching is a modified version (and only the bdf); you can download the original version from [5]. My modification is:

I created the following fonts from DejaVuSans.ttf using ttf2bdf.

I use them as an alternative for unifont, which is fixed-width.

Attached are a screenshot and a tarball with 8 to 12pt versions of the font.
Perhaps they could be included in the official distribution, if others like them.

The MENU key is mapped to close the Chip8 emulator, so mapping it to a Chip8 key is pointless. This makes some games unplayable.

If you add a tank or a plane on a field the strenght does not increase at any time ( as expected ). E.g. place a tank on a field with a farm.

The Bug is located in superdom.c in lines 438 - 457

static int calc_strength(int colour, int x, int y) {

  int a, b, score=0;
  for (a = -1; a < 2; a++) {

          if ((b == 0 || a == 0) &&
              (board[x + a][y + b].colour == colour)) {
              score += 10;

The Bug should be fixed by using this lines instead :

      for (b = -1; b < 2; b++) {

Bomberman like game with ai.
Not finished yet - lots of bugs and things to be done are known :)
Tested on Cowon D2 and also on some simulators with the same screen size (will work on other screen sizes too, but not now).
Somebody test it on iPod Video and on Zen Vision:M please.
Any suggestions greatly appreciated!
Hope the patch will work…

This patch contains several improvements to the Chopper game designed to make it run with a high framerate instead of a low, jerky one. Previously, the game depended on sleeping for a number cycles before drawing another frame, causing very jerky motion. Now the game should run at a high framerate all the time. The gameplay should be about the same, at least on targets with a display of >64px. I don’t have any of these smaller targets, so I wasn’t able to test. Please tell me what you think of my changes.

preamble first :) I am new at the rockbox-project, so this is my first commit. I hope that I am right here with that. If not, please notify, and say, where somewhat would be better.
Strictly speaking this is my first contribition to an opensource-project ever. I am a friend of OSS since years and now I want to give something back ;) I am thinking, rockbox is a nice project to get in the open source scene.

To get in the rockbox-project I tried to improve the jewels-game. First I changed the controls for the Sansa Fuse in the Simulator. The old controls are good for the real Fuse, but very unconfortable at simulator.

Then I wanted jewels to get more difficult with higher levels. To do so I changed it to start with 4 types of jewels only and get one more each three levels till they are 7 types.

When Playing with rockboy on sansa e200 V1 , Rom that have a size of more than 1m Bug and Rockbox often shutdown. And even if these roms run, the speed isn't playable.

There is bug in rockblox: when you manage to push block exactly to the top of the field, game neither finishes with error, neither continues normally. this block starts growing when you destroy lines in the bottom.

I've made small video and put in into youtube (sorry for bad quality and sharpness :
http://www.youtube.com/watch?v=2gULp6yUms8

look into the left top and see what happens when lines are removed. bug is quite easy to reproduce. right side works like the left.

Running “current build” r24477-100203 on Sansa e200 V1

Game Brickmania bug:
The ball just disappears (often on Level 2, but maybe on others). Ball will just usually go to the top corner and not “bounce” back, but the game acts as if a ball is still alive (doesn’t register a lost ball) though there is no further movement on screen. I just have to quit the game.

The ball doesn’t bounce back. No further ball is issued. It just disappears and I can’t interact w/ the game anymore due to no active ball.

FIRST APPEARED: This began a few weeks ago (sorry I can’t be more specific), but has persisted in several “daily build” updates I’ve done and is in the current build I just installed.

REPRODUCIBLE: I reproduce the bug each time I just play through Brickmania. It generally happens in level 2 of the game though it may happen in subsequent levels– I don’t get through to them to see.

I’ve installed with rbuitil and manually, same thing happens. I have 2 different V1 e200s and it happens on both of them.

Thanks for all your work on the great Rockbox.

Sound in all games sounds like chirps or clicks that sounds kinda like the real music on the Nano2G.

On the Official Test Build for the Sansa Fuze, when playing Doom, in middle of playing, Rockbox gives a Data Abort Error. If it doesn't happen in middle of playing, it is always reproducible by entering the second Map. The most recent error i got is "Data Abort at 307B32D4". My Version is "r21704-090707".

It happened once just browsing through the Menu, but is only reproduced every time by playing Doom, which is why I filed it under Doom.

I will try to try a later revision and see if it fixes the bug.

This patch adds a new plugin called aegdice, which allows for AEG style (i.e. 5k3) dice rolling.

FingersOfRock is a DDR variant where by arrows pass over the screen, and the player must press the corresponding buttons in time.

I don’t know how to use the cpu boost, so if someone has some time, please boost when the game begins and un-boost when it finishes.

It is called FingersOfRock from: FretsOfFire and rockbox.

This patch adds more touchpad functionality to the game. It is possible to play by selecting the pieces directly instead of using the simulated buttons.
The changes are:
1. Added touchpad_get_mode to the plugin API.
2. Added menu entry for touchpad devices the switch between button mode and direct mode.
3. The user’s default touchpad mode is save during start-up of the plugin and restored after quitting.
4. The direct input mode is set only during the game (not in menu or view).
5. Extended play loop to handle BUTTON_TOUCHPAD event.
6. A piece is selected by clicking twice on it, moving is also done by clicking the target field twice.

The patch has been tested on the COWON D2 and also seems to compile fine for devices w/o touchpad. The patch has been created with

svn diff -x -w apps > touch_chess.diff

in the root directory. It would be nice if someone could test this (also on non-touchpad devices) and give me some feedback (bugs and improvements).

This is a 3D maze done in vector graphics. I ported David Leonard’s program, which was done with the curses library. Initially, I wrapped the curses functions he used in order to draw the maze with putsxy().
This code is not used at the moment, as the vector graphics are easily scaled and more pleasing. The only issue I see is with the user map, which may be harder to draw on a smaller screen. I developed this on the iPod Video.

This is my first attempt at an open source project, and is a refresher in C for me. I apologize for style. I have tried to make the code as clear as possible.

This patch puts the pacbox emulator onto the cop, leaving the main cpu for audio codec. The COP behaviour is controller by a #define in pacbox.h

If PACBOX_ON_COP is defined, then all iram usage is also turned off, to prevent interference with audio thread.

Additionally, this patch adds an Audio menu (using the playback_control library), which is enabled for all PACBOX_ON_COP and GIGABEAT F-Series builds.

Patch from directly within the apps/plugins/pacbox directory.

The Case Game

Here is a variant of Deal or No Deal for Rockbox.

26 cases contain random amounts of virtual money. After choosing 1 case for yourself, you open the other cases until the banker makes you an offer to buy your case. If you choose to accept the offer the game ends and you receive that offer as your final score. By declining the offer, you continue to open the remaining cases until the next offer. If you decline all offers you get the amount that was in your case as your final score. If play continues until your down to 1 case plus the case you chose, you are given the option to swap cases.

Gameplay controls:

() While opening cases: pressing UP shows the remaining case amounts.

                      pressing DOWN shows the high scores.

() While deciding on an offer: pressing UP shows the previous offers.

                             pressing DOWN shows the high scores.

This game allows name entries into a high score board.

This game currently only works on color lcd screens (Sansa e200 176×220) or greater.

Apply the patch and place the .bmp files in the “apps/plugins/bitmaps/native/” directory.

Please post results for other platforms as well as comments. I tested the game out on the Gigabeat simulator and it seemed to work well.

Patch changes controls for Doom:

Forward: rec/up
Left/Right: scrollwheel (it needs a lot of scrolls for large turns, but hopefully it can be modified to work better in the future)
Back: down
Shoot/Enter (menu): select
Change weapon: left
Open: right
Esc: power

It would be nice if the “Generate” menu-option opened a submenu where you could pick which difficulty to generate.

I’ve had a quick glance at the code, and it looks like it’d have to generate until a suitable difficulty is found, but that’s no different from what users have to do now, if they’re after a specific difficulty, except it’d happen automatically.

If I get the time/motivation, I may have another look at it in the next couple of days.

I am working on adding album art support for FLAC and Ogg files. FLAC looks straightfoward, but there is a design problem with Ogg.

https://wiki.xiph.org/VorbisComment#Cover_art

The struct containing the image and associated data is base64 encoded. I can't just set id3→albumart.pos to a location in the file like all other supported album art formats (and FLAC). Obivously I could allocate memory for the decoded base64 data, but it would have to be deallocated later to prevent a leak.

On IRC, nick_p suggested: "how about adding a new id3 struct element id3→albumart.base64_encoded=true and decoding it when needed on the fly?" This sounds like a good idea, with one issue: it's not the album art alone that is base64 encoded, but the data struct described here:

http://flac.sourceforge.net/format.html#metadata_block_picture

I can test to see if I can parse the beginning of the base64 block, then set the pos pointer to the middle of of the block (with the id3 struct addition) and see if it will still decode.

Rockbox current build :

This patch adds a %ch tag that returns the number of channels in the current file.

Unfortunately, the large majority of codecs don't fill in this field in struct mp3entry. In the codecs covered by the rockbox testfiles collection, only atrac, cook and tta actually work.

I don't think it makes much sense to commit this with so few supported codecs, so help is appreciated on the codec side of things

This patch adds a couple more lines to Track Info for Play Count and Rating.
Currently these don’t seem to show up anywhere else.

Tested against r26427 with Fuze v2 and USim.

This patch removes any total tracks and total discs number from the track and disc number fields in ID3v2 tags, so that track and disc numbers are displayed consistently across different tagging formats.

What happens is that if a number larger than zero can be parsed from the start of the field, then the field is terminated on the first “/” char.

Added as a patch as I don’t know if this behavior is wanted.

This Patch changes the way that ratings work. It’s pretty simple, it reads the rating info from an MP3 files ID3 POPM tag, and converts that to a Rockbox rating value (0 to 10).

You can then use patch  FS#6301  - new tags for WPS and tagcache patch 4 (4_rating.patch) to display the rating on the WPS (tag is %rr). Some Themes use this tag already so I’m not sure if it is in SVN already.

The patch is written for MediaMonkey (alpha 3), but it should work with other version of MediaMonkey, and other programs that put ratings in the ID3 tag (not iTunes).

Tested on iPod nano.

One thing I’m not sure of is what value to return for bufferpos - should this return an int ponting to the next id3 tag position, or is it OK to return it as is? it dosen’t seem to make any difference either way.

Comments are welcome.

Attached is a patch that starts support for the sort tags specified in ID3 v2.4. It adds three new tags to the tagcache system, sortartist, sortalbum, and sorttitle which are drawn from the TSOA/TSOP/TSOT tags.

This is only the beginning and is very, very lightly tested (i.e. it compiles and doesn’t seem to break anything).

Voicing of menus will work fine on the default font. However, if 08-Namil is used, the voicing dies upon reboot.

This patch applies to the tools used to generate voice files and talk clips. It adds basic support for the free SVox Pico speech synthesizer, which is the default speech system on Android phones, and is also available on Linux and Windows. Support for this synthesizer is very basic, because the pico2wave utility used to generate wav files of synthesized speech lacks the ability to set speed, pitch, volume, etc. This patch has so far only been tested for English, although several other languages are supported by the synthesizer. Note that you will need the SVox Pico synthesizer installed on your system. On Ubuntu 10.10 and most recent Debian-based systems, installing libttspico-utils should automatically pull down the correct files. This patch hasn't been tested on Windows, but it should work if pico2wave.exe is in your path.

To build voice files using SVox Pico, apply this patch and run

tools/configure –type=AV

Then select your target from the list. The rest of the defaults should be fine, but be sure to type "p" when the script asks for the TTS engine to use. Then run

make voice

and copy the .voice file into .rockbox/langs. The next time you start Rockbox, you should hear your voice prompts spoken using SVox Pico.

To generate talk clips for filenames and directories using SVox Pico, apply the patch and run

tools/voice.pl -C -s=pico -S= -e=rbspeexenc -E= <directory you want spoken>

Your talk files will be generated recursively in the directory you specify. All _dirname.talk and .talk files that correspond to individual files will be generated, with the exception of the _dirname.talk file for the top level directory you specified.

Please test this patch and provide any feedback you have. Thanks.

This adds the translatable string LANG_DISC for display in WPS themes. E.g. a theme could use the following to show “Disc 2” for a multidisc album:

%?ik<%Sx|Disc| %ik|>

Disc is a 4 or 5 letter word in most languages, so it won’t add much clutter in themes which would like to make use of this. A comparable example is the “Next:” (LANG_NEXT) which is used when displaying the next track in a playlist.

Hi,
There is a problem in the Chinese voicing. It says "number, bai fen ji" (number %), but it's supposed to say "bai fen ji number) (% #). I don't know if it happens in text because I'm blind. Could this be fixed?

This patch attempts to permanently fix the inconsistent mixture of “Title Case” and “Sentence case” in english.lang by applying “Sentence case” to the entire file.

I suggested we do this in a post to the rockbox-dev mailing list last year, but that just ended in a very split discussion with no conclusion.

I’m not sure if this patch wil result in anything different, but I made it for my own use, and thought I would post it, as there were a fair number of posters to that discussion that also prefered sentence case.

The old discussion:

EDIT: I forgot to say this patch also changes a couple of uses of “center” to “centre”…

I would like to change voice strings to make them sound better with a specific SAPI voice.

I don’t intend to change string in *.lang directly.
It should be done in voice.pl dinamically while building voice, shouldn’t it?

This tracker task will be used to house my Summer of Code work. For information about the goals of the project please see http://www.rockbox.org/twiki/bin/view/Main/PluginLocalization . Please read the comments and the descriptions of each patch.

Latest patch:
July 22

The LCD is highly unreliable: sometimes it displays dots and sometimes it stays black.
Example:
http://forums.rockbox.org/index.php?action=dlattach;topic=13462.0;attach=6384;image

- iaudio
both with 3.8 and build r29635

since 3.8 after a while the display blanks totally, no gui. only restarting the device makes it available again for a short
screen, navigation is basically impossible.

at least in the 16bit lcd drivers, all functions which use transparency (or clear pixels) get the pixel colour from the backdrop image, completly ignoring the bg_pattern.

This isnt a problem except in skins where it is perfectly reasonable to want a background image for most of the screen but a solid colour for one or two viewports.

There is a tiny problem though, bg_pattern is set to LCD_DEFAULT_BG which is a valid colour, so we probably need to add a flag to the viewport struct to say if it should ignore the background image or not.

This patch enables display vsync on the iPod Nano 2G, currently only for the Type 1 (LDS176) display. It removes tearing and can make animation smoother. However, right now it uses an extremely CPU-unfriendly method of waiting for synchronization, which makes the display quite slow in some circumstances. I hope to implement DMA to copy the framebuffer, which should help somewhat. However, I am probably going to need some help to do this.

TheSeven gets all the credit for this patch, since he found where the Tearing Effect (vblank) signal was connected to the s5l8701 and wrote the vsync code. All I did was drop it into the display driver in the right spot.

As the title states the c200 v1 LCD doesn't turn on when changing the Backlight setting from Off to On. The backlight itself does turn on though. I don't know if this happens with the v2 players.

I first noticed this behavior in r24404 earlier today on my c240. I then updated the player to r24511-100204 and get the same behavior as before. I also get the same behavior in another c240 v1 player that I have which I also updated to r24511-100204. It was previously running r20698-090412 and the backlight didn't turn on when changing the backlight from off to on (I'm guessing that  FS#10130  fixed that problem) - so it happened sometime between that revision and at least as far back as r24404. It might have even carried over from  FS#10130 .

Also, just as a note, I don't notice this behavior in the February 2nd c200 simulator (r24449) - both the backlight and LCD turn on as expected. I checked my v1 Fuze (r24509) also and get normal behavior (backlight and LCD turn on), so this bug might just be limited to the c200 players.

This patch adds a secondary backlight timeout (similar to what the the iPod OF does).

It adds two extra settings: secondary backlight timeout and secondary brightness (I'm not sure wrt the naming of those, any suggestions?)

The code isn't very clean, but it works (except for CONFIG_BACKLIGHT_FADING == BACKLIGHT_FADING_PWM targets, for which I haven't implemented this).

Please test this.

The patch makes Rec+Vol{Up,Down} in wps and list (main menu) contexts chage backlight brighness. Just like with volume, brightness value is saved in config file. I find this feature quite useful when player is used both indoors and outdoors, eps. on sunny days.

Keymap changes are for Sansa C200 only. Check apps/keymaps/keymap-<you-target>.c and add necessary lines to button_context_{standard,wps} if you use different device.

Diff against SVN revision 22666.

If LCD_SLEEP is put on the backlight queue immediatly after BACKLIGHT_ON, the LCD will go to sleep immediately after the backlight turns on. On the 5G iPod, the next backlight_on() call will wake it, but on some other targets it might not wake again.

For example, consider the following sequence of events:
1) backlight_on() is called, putting BACKLIGHT_ON on the queue
2) The LCD sleep timeout from the previous backlight shutoff puts LCD_SLEEP on the queue
3) BACKLIGHT_ON is received and the backlight is turned on. The call of backlight_lcd_sleep_countdown(false) does nothing about the LCD_SLEEP on the queue.
5) The LCD_SLEEP is received, putting the LCD to sleep again.

This patch causes LCD_SLEEP to be ignored by backlight_thread() when the backlight is on. It also removes a workaround from 5G iPod LCD sleep code.

This issue is theoretical and very improbable. I am not able to trigger this bug in r20774.
