ROM Hack Help! .bclim files to .png?

[Nyannurs]

Hi GBAtemp.

As most of you are aware, some over at the Homebrew subforum have been attempting to hack Badge Arcade. We've arrived at an error, however. The badge files are in the .bclim format, and up until now, we've found no solution to extract a .png out of it and repack it back into the .bclim.

Yes, we already attempted to do this with Kaphotics' tool, bclim2png, which can be found here: https://github.com/kwsch/png2bclim


Any ideas?

Can you upload a .bclim file?

Here's one. https://dropfile.to/30bId
Straightly from Badge Arcade.

Said file has no bclim footer. Looks like its 16bpp.

Try creating a footer with a hex editor and see if it parses.

If you swap files (load def.bclim instead of abc.bclim), does it works ?

Fancy seeing you here. Thanks for the tip, I'll get on to working.

edit: I would have thought I'd find a tutorial online, but no luck. Didn't want to sound like an idiot, but I guess I will have to. How do I make a footer?

I'll try to do one manually and see if it works.

Copy paste from other bclim files (ones with headers or footers) I think

result in pk3DS:

result in png2bclim (same):

Obviously the footer I used may have not been the best fit, but you'd have to tweak it to maybe show up right. Who knows, maybe they have a custom color palette stored in the game files.

Correct footer is as follows. Fileformat is 5.

43 4C 49 4D FF FE 14 00 00 00 02 02 28 20 00 00 
01 00 00 00 69 6D 61 67 10 00 00 00 28 00 28 00 
05 00 00 00 00 20 00 00

For rebuilding just clip off the last 0x28 bytes of the file I guess.

 

[GolyBidoof]

Oh, and here I thought I was smart for figuring it out myself a while ago. Nice stuff man
While we're at it, is there any BCLIM specification in the internet? I have a few more files that share the similar fileformat, but they have less or more bytes (like one image I just dumped which has 0x300 bytes) and I don't know what bytes in the footer do I have to edit to make it work.
This is my file anyway, I added some kind of a footer but I have no idea what size it is.

That one is odd, probably isn't a bclim since there's 384 pixels (3*2^7), which isn't an even*even dimension.

Should also investigate if the method of dumping to obtain these files may have an error...?

 

[GolyBidoof]

It turned out that all the BCLIM files are 8192 bytes in there after all, just sometimes the files look as if they are about to end, but they don't until 0x2000 bytes are over.
Thanks for the documentation, will surely come in handy

Sorry to bump an old thread, but could one of you look at this?

Looks like this:

It's ETC1 + alpha

I'm still lost ;w;

Whenever I put the .bclim file I provided you into png2bclim, it gives me an "Invalid FileFormat" error. I tried setting the BCLIM Output Format as ETC1 and tried both Square/Rectangle options, yet nothing would load the file and give the .png file I need. Did you use the same program, or the pk3DS one (although I think they're the same, idk)?

I'm terrible at working with 3DS stuff, lol. pls halp<3

somebody pls help reis died (or didn't care because i'm so b@d)

 

[gdkchan]

somebody pls help reis died (or didn't care because i'm so b@d)

it works on the old Ohana3DS (the new one doesnt have support for bclim yet)

 

[DarkFlare69]

Uh, you do know that EFE can load BCLIM files and then save them as png?
