WIT: Wiimms ISO Tools v2.00a r2834 - News

wit v2.00a r2834 - 2011-07-08
- Because no bugs (exclude installing) reported since months my WIT tools
seems to be perfect (or ready to use or something between). So it's time
to increase the major version and to proclaim v2.00a. The whole project
consists about 250 000 code lines.
- Bug fix for Windows install script: Remove duplicate WIT entries.

Known bugs:
- The GameCube support is in development and EXPERIMENTAL!
- There are new problems while reading from non seekable sources (e.g. pipes).
The reason is the complete new and more intelligent wiidisc lib which makes
more lookups ==> The best is to use version 1.01c for pipes.
Road map (for some point in the future):
I have already stopped the development in favor of my SZS tools. But there
are some already planned extensions:
- Since many versions the code contains a WBFS extension, enabled by defining
the symbol NEW_WBFS_INTERFACE (set by "make new all"). If enabled, the free
blocks table is managed in a total different way. Already implemented are:
- WBFS access: While opening a WBFS the free blocks table is ignored.
Instead of using the stored one an internal memory map of used blocks is
built. This needs only a part of a second. Some advantages:
- Errors in the free blocks table are irrelevant.
- Blocks overlaps and invalid block assignings are automatically
detected and reported.
- If removing a discs with overlaps, the blocks are still marked used.
- Blocks, that are not handled by the free blocks tables (a result of a
calculation bug in the original libwbfs) can be used.
If closing, a new (and corrected) free blocks table will be written. This
makes the whole process compatible to other WBFS managers and loaders.
- wwt ADD: Before adding a disc it size is compared against the free size
of the WBFS. This allows an early "disc full" error message.
- wwt ADD: If adding a disc a continuous memory block is searched to
minimize the fragmentation.

Missing:
- Report errors while scanning the WBFS.
- The commands "wwt CHECK", "wwt REPAIR" and "wwt EDIT" must use the new
interface.
- GameCube support is still incomplete.
- There are already code fragments implemented to trim discs in three levels:
- Move partitions as whole to eliminate disc holes.
- Move partition sectors to reduce partition size (alternative for
partition scrubbing). Fake signing is necessary.
- Move files of partitons to optimize the step above.
For all trimming levels alignment factors may be set and it should be
possible to set special alignments for GameCube sound files.
- On the fly patching: Create a new image a combination of 2 or more sources.
Therefor trimming is needed.
- A better (real) windows installer.
