Homebrew Custom Theme Thread

[Xenon Hacks]

Not sure if it's somewhere in this thread, but how do you fix the random color (or so it seems, mine is orange) showing on the top left corner? Working on a dark minimal theme and the orange block kinda ruins it. Is it the tool?

Not sure it happens randomly for me

im curious how do you make the top screen picture scroll?

Make it the same size as the bottom.bmp

So whatever original theme cache you use, your modified theme takes on the properties of that original theme. The options I've seen so far in official Nintendo themes, are top screen panoramic 1024x256; top screen 400x256; bottom screen 1024x256 (3 frames), bottom screen 1024x256 panoramic. The themes could use any combination of those options, and for example if you use the body_LZ.bin of the slowpoke theme, then you would have panoramic scrolling on top and bottom pictures. I believe these parameters are set in the original coding of the official Nintendo themes. Is there a way to manually change the coding in the cached body_LZ.bin? Who knows?

Yes. I've been working on improving the format documentation for a bit, and the short answer is to decompress using Every File Explorer, edit addresses 0x10 and 0x24, then recompress. Note that this also affects the size of the texture you should be inputting.

Figured out Home Menu default themes:

It was really simple...

[Rinnegatamante]

I suggest someone to make a new thread (or maybe edit first post) to take on all themes released. It could be very useful for users who wants to see if a specific theme had just been created.

I think that a Wiki page would be better.

What compression type do you use for the body_LZ.bin? I've been messing around but haven't been able to get the theme to load on my 3ds.

LZ11

 

[valyr]

The compsession is lz11 but every file explorer will only decompress it not re-compress it i have been using DSdcmp with a lz11 batch file i found on line dl link here
just drag your body_lz.bin to the batch file then press 0 to decompress or 1 to compress seems to work just fine for me

 

[Gamnaught]

LZ11

Any idea why I might lose store theme sounds for clicking when I change the 0x10 and 0x24 values and re-compress the file with new images?

EDIT: Never mind Every File Explorer just sucks for decompression of LZ11.

I'm seeing your modifications, and thanks for all the RE you're doing.

How do you convert base 255 RGB to RGB888?

do you mean 16bit RGB565 to 24bit RGB888 by any chance or do you
just mean the RGB values?

 

[MrCheeze]

RGB888 is the same thing. One byte (eight bits) for each colour, in order.

As for the compression, using LZ77 instead of LZ11 has been working fine for me. I wonder if one is just an extension of the other?

dont know about the compression but the lz11 files i posted definitely work just fine as well so its highly possible.

With the RGB888 thing the RGB values are reversed in hex aren't they?. Eg BGR? (just checking as i plan on messing with this later)
