<DIV style="text-align: right"><P style="line-height: 0">(2009/02/27)</P></DIV>
<HR>
<H3><A name="note71-01">Note 71-01:(DSP) Updated the audio and graphics components</A></H3>
<P><description>The DSP's internal data transfer process was updated, so the components have also been updated.</description></P>
<HR>
<H3><A name="note71-02">Note 71-02:(DevEnv) Fixed a problem in the arena region of expanded main memory </A></H3>
<P><description>In TWL mode, even if the auto-load module was placed in expanded main memory, this would not be taken into consideration and the expanded main memory arena would be allocated from the start of expanded main memory. This problem was corrected by revising the <CODE>lcf template</CODE> file.</description></P>
<HR>
<H3><A name="note71-03"> Note 71-03:(GX) Clarified the group of functions that ignore settings when the LCD is in the OFF state</A></H3>
<P><description>When the LCD display is in the OFF state the GX circuitry clock is paused, so settings configured during that time are ignored in a number of functions. <br>This fact has been added to the reference information for the following functions.
        <ul>
<li>GX_SetMasterBrightness.html</li>
<li>GXS_SetMasterBrightness.html</li>
<li>GX_SetCapture.html</li>
<li>GX_ResetCapture.html</li>
        </ul>
      </description></P>
<HR>
<H3><A name="note71-04">Note 71-04:(MATH) Revised the TWL-SDK Migration Guide</A></H3>
<P><description>Added the section <I>2.11 MATH MD5 Function Not Recommended</I> to the document $TwlSDK/docs/TechnicalNotes/AboutNitroToTwl.pdf.</description></P>
<HR>
<H3><A name="note71-05">Note 71-05:(MB) Fixed the HYBRID Card application clone boot </A></H3>
<P><description>When a HYBRID-build card application operating in the hardware environment conducted a clone boot, the process would forcibly stop on a CARD library validity check. This problem, which was caused by unnecessary ROM access, has been fixed.</description></P>
<HR>
<H3><A name="note71-06">Note 71-06:(MB) Fixed the multiboot-Model and fake_child sample demos</A></H3>
<P><description>During initialization of the <CODE>multiboot-Model</CODE> and <CODE>fake_child</CODE> demos, if the call to the <CODE>GX_VBlankIntr</CODE> function was late and the child became <CODE>mb_child_***.srl</CODE>, sometimes the screen after the boot would not display. This problem has been fixed.<br><br> Also, the build modes in <CODE>multiboot-Model</CODE> were restricted to NITRO mode for no reason, so this restriction was eliminated.</description></P>
<HR>
<H3><A name="note71-07">Note 71-07:(OS) Added a process to wait for the divider to end when loading context </A></H3>
<P><description>When <CODE>OS_LoadContext</CODE> was called while operating in TWL mode, sometimes the process would exit from the function without waiting for the end of the divider's calculation after the context was loaded.  To correct this, the process now waits for the calculation to end when operating in TWL mode.</description></P>
<HR>
<H3><A name="note71-08">Note 71-08:(PM) Fixed interrupt-specific problem with PM_ForceToPowerOff</A></H3>
<P><description>When the <CODE>PM_ForceToPowerOff</CODE> function was called to turn the power off at a time when interrupts were prohibited and the LCD was in the OFF state, the program would halt. <br> This problem has been fixed.</description></P>
<HR>
<H3><A name="note71-09">Note 71-09:(SSP) Corrected the JPEG decoding process</A></H3>
<P><description>For some images, the JPEG decoding process would not yield the intended decoding result. This has been corrected.</description></P>
<HR>
<H3><A name="note71-10">Note 71-10:(SSP) Fixed problem with SSP_StartJpegEncoderWithEncodeData</A></H3>
<P><description>When JPEG encoding was performed using the <CODE>SSP_StartJpegEncoderWithEncodeData</CODE> function, the thumbnails could not be created correctly. This has been fixed.</description></P>
<HR>
<H3><A name="note71-11">Note 71-11: (TOOL) Fixed tad2rom</A></H3>
<P><description>The program would crash if the argument did not contain the forward slash (  /  ). This problem has been fixed.</description></P>
<HR>
<H3><A name="note71-12">Note 71-12:(WM) Corrected sample demos</A></H3>
<P>In the following sample demos, the port number used for wireless communications differed from the corresponding demos contained in Revolution SDK Extension. This prevented normal communications between Wii and DS systems, and has been fixed.
        <ul>
<li>mp_simple1</li>
<li>datashare-1</li>
        </ul>

<knownissues><description>
        <ul>
<li>If a program built in hybrid mode is run in a NITRO environment, any argument data that was embedded with the <CODE>buryarg</CODE> tool cannot be accessed properly.</li>

<HR>
<H3><A name="note70-01">Note 70-01:(CTRDG)  Made CTRDG_Init a weak function</A></H3>
<P><description>The <CODE>CTRDG_Init</CODE> function could be called from the <CODE>OS_Init</CODE> function without using any CTRDG functions. A number of CTRDG functions would then be linked, taking up a large amount of memory.<br> The <CODE>CTRDG_Init</CODE> function has been converted to a weak function. For applications that do not access Game Paks, definitions can be altered to reduce the amount of memory taken up by the CTRDG  library.<br> For more information, see the <CODE>CTRDG_DummyInit</CODE> function.</description></P>
<HR>
<H3><A name="note70-02">Note 70-02:(DevEnv) Revised the TWL-SDK Transition Guide</A></H3>
<P><description>Added information to sections 3.1 and 5.1 in the <CODE>$TwlSDK/docs/TechnicalNotes/AboutNitroToTwl.pdf</CODE> documentation, mentioning that the library uses more memory when you transition from NITRO-SDK to TWL-SDK NITRO or HYBRID ROM.</description></P>
<HR>
<H3><A name="note70-03">Note 70-03:(FS) Split up the FAT driver initialization functions</A></H3>
<P><description>Because normal card-boot applications do not use NAND system memory or an SD memory card, the FAT driver initialization function has been split up so applications do not link to FAT drivers when they do not need to.<br> If  your HYBRID build card-boot application uses NAND system memory or an SD memory card, you need to call the <CODE>FS_InitFatDriver</CODE> function in addition to the <CODE>FS_Init</CODE> function.</description></P>
<HR>
<H3><A name="note70-04">Note 70-04:(FS) Fixed a bug in the FS_SetSeekCache function</A></H3>
<P><description>If the address for the start or the end of the buffer specified by the <CODE>FS_SetSeekCache</CODE> function did not align with the cache boundary, subsequent seek operations were unpredictable. This bug has been fixed.<br> Accordingly, the <CODE>FS_GetSeekCacheSize</CODE> function now returns a 64-byte value to accommodate cache boundary padding.</description></P>
<HR>
<H3><A name="note70-05">Note 70-05:(FS) Fixed a bug specific to system shutdown</A></H3>
<P><description>If the power button was pressed while a 2 MB or larger file was being written or read from NAND system memory, the shutdown sequence occasionally would not complete. That bug has been fixed.</description></P>
<HR>
<H3><A name="note70-06">Note 70-06:(FS) Fixed a bug specific to working with long path names</A></H3>
<P><description>When dealing with path names that reached the FAT upper limit of 255 characters, operations that should succeed would occasionally return <CODE>FS_RESULT_NO_ENTRY</CODE> and fail. That bug has been corrected.</description></P>
<HR>
<H3><A name="note70-07">Note 70-07:(GX) Revised the GX_SetDefaultNDMA function</A></H3>
<P><description>When a HYBRID build was operating in NITRO mode, the <CODE>GX_SetDefaultNDMA</CODE> function would be called. That has been corrected.</description></P>
<HR>
<H3><A name="note70-08">Note 70-08:(MB) Reduced the amount of memory consumed when using MB parent</A></H3>
<P><description>The buffer used for scanning when using MB child functionality (DS Download Play only) was also linked when using MB parent functionality. To reduce memory consumption, this has been revised so the buffer is not linked when it is not needed.</description></P>
<HR>
<H3><A name="note70-09">Note 70-09:(PM) Added a note to the PM_SetLCDPower Function Reference</A></H3>
<P><description>As a result of the revision described in <a href="changelog.html#note69-13">Note 69-13</a>, you no longer need to make a separate call to the GX_DispOn function when you use the the PM_SetLCDPower function to turn the LCD back on. This has been added to the function reference.</description></P>
<HR>
<H3><A name="note70-10">Note 70-10:(SND) Added API for changing sound volume</A></H3>
<P><description>Two functions, <CODE>SNDEX_SetIgnoreHWVolume</CODE> and <CODE>SNDEX_ResetIgnoreHWVolume</CODE>, have been added. They allow you to preset a value that you want to use to change the sound volume, to temporarily change to that value, and to revert back to the original volume.<br> You need to conform to the Programming Guidelines when using these two functions.<br><br> In addition, the <CODE>$TwlSDK/build/demos.TWL/snd/ignoreHWVolumeDemo</CODE> sample demo has been added. The demo uses these two functions to play sounds at the specified volume for a specified time.</description></P>

<HR>
<H3><A name="note69-03">Note 69-03:(DSP) Changed the DSP_PlayShutterSound function</A></H3>
<P><description>Until now, <CODE>FALSE</CODE> was returned when forced output of the sound failed inside the  <CODE>DSP_PlayShutterSound</CODE> function. That has been changed so the process is now retried inside the function until it is successful.<br><br> With this revision, the <CODE>DSP_PlayShutterSound</CODE> function now only returns <CODE>FALSE</CODE> when the specified shutter sound does not match the I2S operating frequency.</description></P>
<HR>
<H3><A name="note69-04">Note 69-04:(DevEnv) Updated the TWL-SDK Transition Guide</A></H3>
<P><description>Text about the <CODE>Static</CODE> module in NITRO ROM has been deleted from <CODE>$TwlSDK/docs/TechnicalNotes/AboutNitroToTwl.pdf</CODE> because it is not needed starting with TWL-SDK 5.1 PR.<br> In addition, some of the text about ROM archives in NAND applications was edited for accuracy.</description></P>

<HR>
<H3><A name="note69-14">Note 69-14:(SND) Added the SNDEX_GetCurrentVolume[Async] functions</A></H3>
<P>There are now two types of sound volume values: the sound volume of the console, and the pending sound volume (see also <A href="changelog.html#note69-15">Note 69-15</a>).<br>Therefore, the <CODE>SNDEX_GetCurrentVolume[Async]</CODE> functions have been added to get the current console volume value.<br>The <CODE>SNDEX_GetVolume[Async]</CODE> functions get the pending volume value. If there is no pending value they get the current value.<br><br>The pending volume value is applied after several frames, so if <CODE>SNDEX_SetVolume[Async]</CODE> functions are being frequently used, or if you do not want to get the exact sound volume of the console at the time the function is called, there is no need to use the<CODE>SNDEX_GetCurrentVolume[Async]</CODE> functions.</P>
<HR>
<H3><A name="note69-15">Note 69-15:(SND) Restricted repeated execution of SNDEX_SetVolume[Async] functions</A></H3>
<P><description>There is a limit to the number of times that the sound volume value can be stored in dedicated nonvolatile memory, so restrictions have been placed on the <CODE>SNDEX_SetVolume[Async]</CODE> functions. Sound volume values set by functions are held pending for roughly 10 frames before they are written. After the pending time has ended the value that is written is the value that was most recently set.</description></P>
