Tool for viewing and editing .gbb files used in Brian Lara Cricket '99 / Shane Warne Cricket '99.

- Decode .GBB files into viewable 24-bit BMP images.
- ️ Re-encode edited BMPs back into the .GBB format with original compression preserved.
- Correct aspect ratios for non-square and stretched textures.
- ️ Drag-and-drop support, file association, and metadata viewing.
.GBB files store raw 24-bit textures using:
- Run-Length Encoding (RLE) or
- Bit-packed delta compression
The texture dimensions are stored at the beginning of the file. This tool reverse-engineers that logic to allow safe texture replacement without corrupting the original file.
