The original blur.exe from 2010 often crashes on modern hardware. Most repacks use a modified blur.exe (version 133) that bypasses Games for Windows Live (GFWL). The older language packs conflict with this modified EXE, causing text to appear as #### or blank boxes. The "133 new" pack has recompiled font tables to fix this.
: Blur can run on systems with as little as 4GB of RAM.
The pack typically consists of a compressed archive containing .wad files (the proprietary archive format used by Bizarre Creations) and updated configuration files ( localization.ini ). Technical analysis indicates that Pack 133 does not merely replicate the original 2010 English files. Instead, it incorporates corrections for known text overflow errors in the UI where original strings exceeded the allotted text boxes, particularly in the "Fan Run" objective descriptions.
