Could you guys post a example for decoding the preview image? i cant figure out the 8x8 tile thing. i will give credit to you:).Preview of what i have: [[Image:FlipnoteImageDecodedByPBSDS.png]]--[[User:Pbsds|pbsds]] 09:29, 24 December 2009 (UTC)

Thanks:)--[[User:Pbsds|pbsds]] 09:55, 24 December 2009 (UTC)

It doesn't work! Here is the code im using(i had to transelate it):
<source lang="">Dim $ImageOutput[4072]
for $x=0 to 46 step 1
for $y=0 to 7 step 1
for $z=0 To 7 Step 1
ImageOutput[($x*64)+(16*$y)+(4*$z)] = RawImage[($x*64)+(32*$z)+(4*$y)]
ImageOutput[($x*64)+(16*$y)+(4*$z)+1] = RawImage[($x*64)+(32*$z)+(4*$y)+1]
ImageOutput[($x*64)+(16*$y)+(4*$z)+2] = RawImage[($x*64)+(32*$z)+(4*$y)+2]
ImageOutput[($x*64)+(16*$y)+(4*$z)+3] = RawImage[($x*64)+(32*$z)+(4*$y)+3]
Next
Next
Next</source>
Output: [[Image:Test2.png]]

You made a typo here:
for x=0 to 46 step

Made no difference...--[[User:Pbsds|pbsds]] 21:08, 24 December 2009 (UTC)

If you would've used a sane language, you would've gotten a segfault. :-)

Please do some research on the tiling, my code is written for the 32x32 icons you see in the DSiMenu.

I had to set the RawImage and the ImageOutput arrays to 1000 more pixels than needed to avoid the segfault.

I think i'll try again tomorrow. but now im off to bed:)--[[User:Pbsds|pbsds]] 00:39, 25 December 2009 (UTC)

== Pallete ==
i don't think my RGB pallete is perfect... Could someone post a RGB version of the pallete? My pallete have too sharp colors :( --[[User:Pbsds|pbsds]] 01:03, 4 January 2010 (UTC)

Maybe i should post my pallete so you guys can check if its wrong:

0 = FFFFFF

1 = 525252

2 = FFFFFF

3 = A4A4A4

4 = FF0000

5 = 7B0000

6 = FF7B7B

7 = 00FF00

8 = 0000FF

9 = 00007B

A = 7B7BFF

B = 00FF00

C = FF00FF

D = 00FF00

E = 00FF00

F = 00FF00

Use the following formula:
(x / 32) * 256
To convert between the scales 0-31 and 0-255.

Has anyone managed to get a modified PPM file running on the DSi? If so, can you update the wiki with your findings.
