Hacking [release] BFLIM Extractor

[AboodXD]

BFLIM Extractor v2.1​

BFLIM Extractor is a tool for extracting and creating .bflim files used for layouts' textures in some of the Wii U games.

Supported texture formats:

• GX2_SURFACE_FORMAT_TCS_R8_G8_B8_A8_UNORM (ABGR8 / BGR8)
• GX2_SURFACE_FORMAT_TCS_R8_G8_B8_A8_SRGB (ABGR8 SRGB / BGR8 SRGB)
• GX2_SURFACE_FORMAT_TCS_R10_G10_B10_A2_UNORM (A2RGB10)
• GX2_SURFACE_FORMAT_TCS_R5_G6_B5_UNORM (RGB565)
• GX2_SURFACE_FORMAT_TC_R5_G5_B5_A1_UNORM (A1RGB5)
• GX2_SURFACE_FORMAT_TC_R4_G4_B4_A4_UNORM (ARGB4)
• GX2_SURFACE_FORMAT_TC_R8_UNORM (L8 / A8)
• GX2_SURFACE_FORMAT_TC_R8_G8_UNORM (A8L8)
• GX2_SURFACE_FORMAT_TC_R4_G4_UNORM (A4L4)
• GX2_SURFACE_FORMAT_T_BC1_UNORM (BC1 / DXT1 / ETC1)
• GX2_SURFACE_FORMAT_T_BC1_SRGB (BC1 SRGB / DXT1 SRGB)
• GX2_SURFACE_FORMAT_T_BC2_UNORM (BC2 / DXT3)
• GX2_SURFACE_FORMAT_T_BC2_SRGB (BC2 SRGB / DXT3 SRGB)
• GX2_SURFACE_FORMAT_T_BC3_UNORM (BC3 / DXT5)
• GX2_SURFACE_FORMAT_T_BC3_SRGB (BC3 SRGB / DXT5 SRGB)
• GX2_SURFACE_FORMAT_T_BC4_UNORM (BC4L / BC4A)
• GX2_SURFACE_FORMAT_T_BC5_UNORM (BC5)

Why so complex?
Wii U textures appear to be packed using a complex 'texture swizzling' algorithm, presumably for faster access.

Nice work.

Thanks.

Cool!

 

[EpicLPer]

Any way to extract a whole folder at once?

Batch is your friend (converts all BFLIM files in Convert folder):

@ECHO OFF
FOR %%f IN (Convert/*.bflim) DO (
    ECHO Converting: .\Convert\%%f
    BFLIM_EXTRACT Convert/%%f
)

Suggestions:
- Please don't wait 5 seconds to display errors. Horrible in a batch process. Maybe just do that if started without any parameters to make users just clicking the exe see it.
- Support output path
- Don't open input files with write access (errors out when read-only flag set)

I like your effort. Format 0x10 and 0xF is heavily used in MK8, looking forward for support. Sadly, the other formats are not unswizzled correctly most of the time.

Suggestion: Add a /nowait option or something, also a /folder maybe to make it easier

But it's still early so yeah, we'll see

PS.: Oh boy I'm so hyped for all the dick texture replacements people will come up with then lol (sarcasm)

 

[Deleted member 370174]

NOWAIT? You stole that name from Commander Keen right?
Anyway, don't do that, a command line tool should never wait needlessy, so handle it cleverly just when displaying help.

 

[AboodXD]

All your requests are too easy to implement.

@EpicLPer Use:

for %%f in (Path/*.bflim) do bflim_extract Path/%%f

Files which end with ^l are RGBA32 files, those are 100% tested and they work perfectly.
Files which end with ^o, ^p, or ^q are BC compressed, those are 100% tested, for some odd reason the output image gets cut in half... :/

Everything else isn't supported, and will be soon.

Nice work. Too bad my Python skills are ridiculous at best. I was hoping to fork and implement the requested changes right away (no sleep, error code semantics) just as a practice section.

What are the references on these file formats?

 

[AboodXD]

What are the references on these file formats?

Sorry but I didn't understand what you said.

I love how Nintendo keeps reusing formats, as this format is the same as GFD (.gtx), except changes in header.

 

[Spidey_BR]

I mean the documentation on how these formats work. Or are they industry standard for texture files?

 

[AboodXD]

I've already made a documentation of the GFD (A very similar format to BFLIM, they're both used on Wii U) File format, you can find it here:
https://github.com/aboood40091/GTX-Extractor/wiki

It's a bit incomplete but that doesn't matter that much.

I can still make a documentation of the BFLIM File format if you want.

Please note that both GFD and BFLIM formats are very complex.

 

[Deleted member 370174]

Documentation never hurts, would be great if you can do it.

 

[AboodXD]

OK, I'll work on it.

BTW, can I get a list of features you hope to see?

 

[Deleted member 370174]

For me it's just the bugs I posted in my previous post, if you want =3
- Don't wait 5 seconds
- Don't open input files with write access
- Look at the other format which completely throws up due to wrong swizzling (the greenish blocks)

 

[AboodXD]

Can you send me those BFLIM files to test?

- Don't open input files with write access

I don't understand, sorry.

 

[Deleted member 370174]

If you call open, don't pass 'w'. That makes the program crash being incapable to open files with a read-only flag. Just open them with 'rb'. I send you the files as a PM

 

[AboodXD]

If you call open, don't pass 'w'. That makes the program crash being incapable to open files with a read-only flag. Just open them with 'rb'.

This is not the case, this is the line where the input file gets read:

with open(sys.argv[1], "rb") as inf:
