There's an updated 0_download_json script on post #800. A troubleshooting guide is on post #817. Some of the burst skin files are on post #824 but they don't currently work with the player. I occasionally attach JPG or PNG archive with the DMM character's files in it, such as post #826. The method to opening them is explained in post #674 (and also in the troubleshooting guide).
Edit 1: Updated the troubleshooting guide to include a post #800 link for the DMM 0_download_json script and the links to the newest DLpy scripts.
Edit 2: Updated to include the DMM files for Nephthys [Anti-Mind] and Pruflas [Anti-Mind], as well as the troubleshooting guide so that it mentions these characters. I used the method described in post #820 to download the files.
Edit 3: Updated both DLpy scripts, the troubleshooting guide (mentions the newest DLpy script location), and attached the DMM files for Lüin and [Memorial0019] Lydia.
