Homebrew [DsPico] Made a small web app to create themes easly for Pico Launcher

Theme Creator - Pico Launcher

Hello friends, as the title says, I created a small application where you can upload the images you want to use as a theme and it gives you a .zip file with the files already ready. Just copy the unzipped folder to the SD card, edit the settings file, enter the name of your theme, and you're done. It also has a .bin decryptor, so you can see what settings other themes that are already out there are using.

If you have any suggestions, they are welcome.

Thanks for the suggestion. I’m currently looking into how the files work in a bit more detail; the problem is that this would involve modifying files that aren’t part of the configuration the developers left for themes.

Hi! Here is the audio that is out of sync.
It's going to sound normal outside of DSPico cartridge / whatever Ds you put it into. But as soon as you get the menu up the music starts out of sync. I hope this information helps!

https://github.com/libertyernie/LoopingAudioConverter. Set output to [VGAudio]BCSTM. Place output files in "bgm" folder in your theme folder. DONE!

Is there a way of editing a theme without having to start from scratch?

Is there a way of editing a theme without having to start from scratch?

yes, you dont have to start from scratch. a theme is just a folder in _pico/themes on
the sd card. the settings are in theme.json, plain text you can edit directly, and the
images are the .bin files. so you can copy the folder of a theme you like, rename it,
edit the json and replace only the images you want. the decryptor in this tool helps
with the last part, you can look inside the .bin files of themes that are already out
there

(i know the format from spending time in the launcher code)
