Hey guys A few days ago I was discussing with @daniel26150 about how we could help undubbing Smash Bros for 3DS/WiiU Since the thread was more about texture hack than undubbing I thought I would make its own thread. Here's what I've got working so far: Sorry for the poor quality, I don't have the proper equipment to record it. Thanks Before anything, I want to thank Sammy Husky for his tool Sm4shCommand, and more particulary for DTLSExtractor, the creators of BrawlLib and chrrox and his BMS script which helped me getting started. Here's everything that I was able to undub: - Character movies - Fox/Paluntena dialogs - Fighers Little Mac, Pit, Dark Pit, Palutena, Ike, Robin, Metaknight, Fox, Falco, Lucario, Jigglypuff, Greninja, Wiifit Trainer, Shulk, Lucina, Sonic with their original voices - Pokemon with their original dubbing (for some of them) - Assist trophies with their original dubbing (for some of them) - Menu (They're in english, but slightly different) - Wiifit Stage - Kirby copy sounds (for Shulk, Robin and Palutena) - Applause sounds (havent tested all of them, but they should work) Now the one thing I can't really try is the sounds for the DLC characters, since I use Loadiine to try the hack. But Mewtwo via Amiibo looked fine. What's the method? - Get a dump of Smash 4 JPN. Keep in mind that the core file sounds are in english, even in the JPN version. What you're looking for is in data(jp_jp). - For movies/fox&paluneta sounds, simply rename and replace them in their original folders, it works :-) - For everything else, you can basically "add stuff" to the patch folder and have the game consider it as part of the latest patch. patchlist list all the files that the game needs to override, and the different resource files provide the game with some additional information about the files (size of the file added, are they part of a pack, what offset for each file in a pack, etc...). So yeah, basically, you can modify/add anything (ever bigger files than their original) as long as you know how to repack the resource files, which is made a lot easier by studying DTLSExtractor's source code. I will take a look at the 3DS version and see how it works, but I would think it uses a similar system.
