Lunaboy - is it possible to do a back conversion?
(BMP or TGA back to BTI)

**antidote** · August 7th, 2009, 16:33

Yes it is, according to Thakis, BTI is just a custom dxt3 image file (DDS).

antidote, thanks, but - is there a some tool for this?
Or any explanation - how to do such conversion with Thakis' "BTI dump" or Lunaboy's "BTI converter"?
Such specs are nothing for me, I'm not a programmer...
The tool would be great...

Also, it would be very cool not only to convert edited images to BTI, but also to pack all stuff to a *.rarc file back, from which those images are extracted. (on Thakis's site there is only "RarcDUMP"-er. No reverse process).

I need all this for a translation of ZeldaTP to russian.
I'd like to redraw some images (bti) to russian.
As for script translation - I use RARC files directly. No need to extract these for a script translation.

But in case of BTI files - each RARC contains more than one *.bti file + directories. So I need to pack all this stuff back to RARC after editing.

I don't think there is a tool *currently* however making one would be trivial.

I'm busy trying to crack the MP3 .pak since SaraHarp hasn't released his spec document on it, otherwise I would write one.

It would be very nice, if you'll write such tool.

At your request I’ve written a simple TGA to BTI converter.

The converter is a console application and can convert 24 or 32 bit uncompressed TGA files to Rgb4A3 and Rgb565 BTI files. You can select the output format (Rgb4A3 or Rgb565) with a command line parameter. The Rgb4A3 format includes the alpha-plane from a 32-bit TGA file. For more help, run the program without parameters.

Be aware that the size of the output file might be larger than the original BTI file, since palette based files are not supported. This might be a problem if you inject the converted BTI files inside original game images without rebuilding the file-table. When you’re rebuilding the image (create a new image from a list of files), the increased file size shouldn’t be a problem.

Because I get an 'Unable to move/copy file' error while uploading the attachment, I'm using RapidShare:

Have fun.

Lunaboy - Thanks a lot!
I'll try this ASAP.

I think there will be no problem inserting it to iso with this tool:

The converter works just fine.
Thanks again!

But there are still any tool to pack extracted contents of RARC files back to RARC...
Doing this in Hex-editor for now...

Couldn't you have dumped the textures using Dolphin?

Please upload again the tga to bti converter
