- Fixed dumping DLCs and AC w/p data - Added an Install all PKGs option for folders with more than 1 PKG - Installing a PKG will no longer boot you back to settings - Carried over some improvements from the PS5 version of IF - Replaced reg. vectors for ThreadSafeVectors - Added the Chinese lang files - Fixed a bug that would cause the Utility thread to deadlock - Fixed a Bug that caused the daemon not to give a backtrace on 9.00
