Hi, wanna bet ? The music files are wav files and start at MDATA.300. With my movie patch, link's under the www button in this post, you can replace them with anything, that you like. I also have an older version of the Smacker tools on my site, that lets you replace the movies (tutorial included). EDIT: Ok, I just wanted to add something, that is really important to me. Since I'm behind a slow (28k with 56k modem, dunno why either) dial-up connection I beg you all to compress your sound files, before sending them. I can decode almost anything (asf could be a problem, but who's using it anyway ?) back later, so that's not the problem. You can use whatever program, that you're comfortable with to convert them to mp3s for example, like Cool Edit, Tmpeg, AudioCatalyst, ... , basically a 128kb mp3 would work perfectly. If you don't have one of said programs, you can download Lame encoder 3.92 and the easy to use GUI Enlamer for this purpose. Thanks, guys
