But when I hit X to save it, it goes back to theme shuffle off. How do I keep it turned on?? oh, am I not supposed to hit X again? Just hit start and leave the program?
You don't need the smdh files, it works without. On the first page you see one theme with an icon, that's the smdh. The others with just 3 letters are how it appears if there isn't one.I wanna try the shuffle thing with some themes I have.
Does anyone have any smdh files for Pokemon Mystery Dungeon? I need 2 of them.
(I'm too lazy to create them myself as I'm away from a computer...)

Have you ever used themes before?Every theme I try I get a error saying
Error: [string "?"] :159: cannot access ext data archive
Press A to restart
Press B to exit
Press Y to enable FTP Server
FTP state: OFF
Can anyone help resolve this for me.

Have you ever used themes before?
Try doing thisOn 3ds no as I got the same error with chmm1

Try doing this
Home Screen -> Set a simple theme, like black -> boot into *whatever*hax, go to chmm2 and see if it works

Also, I finally understood why my BGM.ogg files weren't working for me.
The .ogg files must be encoded through libsndfile (so this means that any other libsndfile extension might work just fine, like .au or .aiff). Xiph OGG container, that is the default encoder for .ogg files in Adobe Audition and other audio editing programs, has a way more efficient compression but has limited compatibility
So, if you're encoding .ogg files, just make sure to not use the Xiph container
got it, thanksAIFF doesn't work with Vorbis audiocodec but with PCM16 audiocodec (as you can see in luaSound source). It's like a WAV continaer but with Big Endian as endianess.
