* Dead Or Alive: Dimensions Photo Decrypter *
*********************************************
* instructions: *
* - make photos in showcase mode if you *
* haven't *
* - find your dead or alive folder in *
* extdata on SD card. if you made photos *
* it should have folder 00000000 with *
* files with size of 400416B inside. EU *
* version is 0000038a *
* - move it off the sd card to your pc *
* - disable wireless switch on 3ds so no *
* DLC is received while you screw around *
* - check how many files there are in *
* the folder you put on your pc *
* - start the game, create new SD data *
* - go to showcase mode, set stage to *
* training stage and choose crouching *
* hayabusa figure *
* - make as many completely black pictures *
* of the background, as you have files in *
* the folder on your pc, with 3d switched *
* on. it is important that only black is *
* on your pictures!! *
* - switch off 3ds and remove SD card *
* - move the new folder to your pc, but do *
* NOT overwrite the original *
* - copy original back to the SD card *
* - you can switch wifi back on and play *
* - now you can decrypt. take picture files *
* with the same filename from both *
* folders. pictures are 400416B *
* - in cmd.exe, call: *
* doadpd.exe blackfile originalfile *
* - if black file was black and both files *
* have the same number, you should have *
* originalfile.l.tga and *
* originalfile.r.tga in same folder now *
* - you can open tga with GIMP to convert *
* to PNG or JPEG *
* https://www.gimp.org/ *
* - if you want, you can even make MPO file *
* with software called StereoPhoto Maker *
* so you can view in 3D: *
* https://stereo.jpn.org/eng/stphmkr/ *
* - if you can code, feel free to make *
* better program *
* no warranty, if you screw up and lose DLC *
* it's on you *
