Wiimms ISO Tools v2.27a

[tabs:2.27a]wit v2.27a r4908 - 2014-01-31

- Bug fix: If extracting a GameCube image, files larger than 4 MiB are
damaged at beginning of this 4 MiB offset.

- New feature: If creating a GCZ image, a blockwise z-compression is tried.
If the compressed data is larger than 98.5%, the uncompressed data is
stored. New is, that encrypted blocks are stored directly as uncompressed
data, because encrypted are very bad compression candidates and the 98.5%
test fails all the time. This makes GCZ creation faster. The new option
--gcz-zip disables this optimization for encrypted data.

- New option: --gcz-block=size: Define the block size for GCZ creation. The
default size is 16K (also Dolphins default).

- Tool 'wdf' supports info dumps of GCZ files to verify the GCZ creation.

- New command for wit+wwt: FEATURES: Print a list of supported features. The
output is machine readable. Scripts may use "wit features -qq" and check
the exit status.
[tabs:2.25a]wit v2.26a r4863 - 2014-01-22

- Bug fix: Because of a bug after implementing the auto split detection,
reading source images failed, if using stdin for parameters.
- Support for Dolphins file format GCZ (GameCube Zip):
- All commands detect and accept GCZ files as input file.
- Creating of GCZ files is also supported, but EXPERIMENTAL until final
tests have been done.
- New option --gcz force GCZ output.
- Patching of GCZ files is not possible, because the GCZ file structure
doesn't allow modifications (size of compressed data must not change).
- Composing an image to a GCZ file is not possible, because it needs
patching checksums and header after writing the complete image.
The GCZ support is very new, so please use it only with backups of your
images and don't be anger, if it destroy something.
[tabs:2.25a]wit v2.25a r4825 - 2014-01-03

- New option --auto-split: If set, the tools try to find out, if an image
split is needed. The split size is then either below 4 or 2 GiB. Auto-Split
base on tests with fseek() and works fine under Linux, but it don't work
with Cygwin. Mac is unknown. In future versions --auto-split is enabled by
default. It is disabled by any other split option.
- New option --no-split: Disable file splitting at all. At the moment and in
old versions of the tools, this is the default.
- wwt CHECK+REPAIR: Support for option --sections.
- Windows only: Cygwin update to v1.7.27 2013-12-09.
