ROM Hack Viewing other photos on DSi

[Bkid]

I believe most people have given up on trying to do this, but I figured I would at least give it a shot.

I started by taking a blank picture (with my thumb over the camera), and transferring it to my computer. I then used a program called Exifer to export the EXIF data from the picture into a .exi file. I found a random picture on Google, fixed it up in Photoshop to be 640x480 and 72DPI, and exported it as a JPG. I opened the picture in Exifer and imported the EXIF data from the DSi photo into this photo. The one noticeable downside to this is that the thumbnail is replaced with the DSi photo's thumbnail (in this case, a black thumbnail).

Putting this new photo on my DSi and starting it up obviously did not work out too well. The good news is that I was at least able to get the DSi to recognize the picture, though it would just say "Cannot Display Image" in a gray square. I've heard of people getting this far, if not further, so I was wondering if anyone would have anything to contribute to this.

well if you make the picture to 640x480, i believe the DSi will not display the image. Try resizing it too 256x192.

But the pictures from the DSi themselves are 640x480, so I don't see why not..

edit: Tried anyway just for the hell of it and it still didn't work.

DSi photos are encrypted with a key that still allows them to be viewed on other devices, but not allow other devices' photos to be displayed on the DSi because they aren't encrypted with that key. Until the key is found, there is no way to view other pictures on the DSi.

well he said that he could make dsi react to the image that he 'modified'. so i guess the 'key' for encrypting is in the programs, and if we can change that 'key' so it can working i guess we can import our photos to dsi?

The DSi knows the image is modified because they key doesn't decrypt the image properly. Unless the DSi gets hacked then there is no way to find the key to add custom images.

A much easier way to get photos on to Your DSi: (Not all that convenient, but good enough)

Choose a picture from your computer.
Print it.
Picture it with the DSi.

or cut out the print part

I found something called a makernote, which was located in the DSi photo, but I don't think that's it. It was copied over to the test picture as well, but of course the picture didn't work out..

A slightly quicker route

doesn't work that well with reflective screens

Exactly the point

Printing and Picturing is way better

Unless of course, you don't have a reflective screen...
