So just to let you guys know, I've replaced the file on CodePlex with a fixed one, so re-download it for the following fixes:
-All games regions were incorrectly being detected as NTSC on the right-hand list
-Games with “:” in the name were failing during batch extract operations.
-Fixed an issue with dragging and dropping folders not detecting RAR files inside the folder and only detecting ISO files.
-Incorrect estimated sizes for some games.
(If any other WBFS tools out there are having this issue, please let the author know that theres a bug in libwbfs here:
in wbfs_estimate_disc:
return tot * ((p->wbfs_sec_sz / p->hd_sec_sz) * 512);
it should be
return tot * (((p->wbfs_sec_sz*1.0) / p->hd_sec_sz) * 512);
and you should be returning a float, so fix the method's signature.
