* Important News * A new version will be released soon. Some of the new features: - Themes WILL NOT get deleted if you visit the eShop or the Theme Shop (very special thanks to @redunka): Here's a teaser for this feature: https://gbatemp.net/threads/release...d-official-themes.401081/page-36#post-7315611 - Theme packages lists can be saved and loaded. Also, you can create your own "pre-made" theme packages. Allow me to introduce you: "Howling Theme Tool". A noob-proof tool to pack your custom themes as .CIA files to be used in Custom Firmware. * Features * - Allows to pack up to 100 themes in one CIA file (the 3DS home menu limit). - Creates US, EU and JP theme packages. - Allow theme, icon and bgm preview. - Separates Custom, NSFW and Official themes. - Name arrangement feature. * To do list * - Other arrangement options (up / down buttons and stuff) - Try to Gateway compatibility if possible or if I get lazy, send GW a mail asking them to patch what they don't patch. * How to use * 0.A - First of all, I recommend to run the "Theme Checker" to verify if your themes are in good condition. Open "Theme Checker", select your theme's folder and then press "Start Verification". 0.B - If the program notices a missing file in your theme, it will let you know. By example, if there is no "icon.png", the application will look for "info.smdh", if the file exists, it will extract the icon from there. If there is no "name.txt" it will ask you for a name for the theme, based on the folder's name. 0.C - Wait until it finish and you will be ready to go! 1-Set-up your themes and folders fellowing the directions in the "Example Folder" in the release package (more info below). 2-Open the application. 3-Select your theme's folder location and press "Start" 4-Select the themes you want from the available themes and add them to the "Themes to pack" list 5-If you want, arrange them (I recommend arrange them from Z to A so the will appear from A to Z in the 3DS) 6-Compile your theme package (the region you select must match your emunand's region) 7-Wait some seconds... 8-Select a place to save your theme package 9-Done! You have your package ready. Now copy it to your 3DS and install it with your favorite CIA installer. * Folder and theme's structure * You must create a folder with this structure to work with Howling Theme Tool: And your themes must have this structure: Even if "icon.bmp" it's no longer required since v1.5.0, "icon.png" it's still required and every theme must have one. The "icon.bmp" will be automatically generated based on "icon.png" while creating a theme package. To be sure your themes are ready to be used with "Howling Theme Tool", please run the "Theme Checker" and check your theme's folder. "Theme Checker" will also generate proper "icon.png" and "name.txt" based in "info.smdh" and the folder's name. * Notice * This only works under Custom Firmware (tested on rxTools and Player's Heaven) at the moment. Gateway forgot to patch the DLCs integrity check, so it will fail to install due to the "plain" control file. If someone wants to send a mail to GW to give them some feedback about this, remember to do it with "respect" and please, do not "FILL" their inbox with "cloned" mails. * Does this really works? * Proof: Warning: Spoilers inside!
