To understand the significance of the FitGirl release, one must first understand the concept of a "repack." A repack is a compressed version of a game, often stripped of redundant language files or unnecessary cinematic duplicates, designed to minimize download size.
FitGirl is arguably the most prominent name in this space. Her releases are known for high compression ratios, meaning a 50 GB game might be downloadable in under 20 GB. However, to install these games, users often require a "crack" to bypass Digital Rights Management (DRM). This is where groups like CODEX come in.

Prior to December 18, 2019, FitGirl offered a repack of the base CODEX crack. However, users complained that the repack was "heavy" (roughly 18GB compressed, 46GB installed) and that the DX12 mode was buggy.
The update came with a new steam_api64.dll and re2.exe. CODEX had to re-bypass Capcom’s anti-tamper (which was a customized version of Denuvo, though stripped in the crack). The 20191218 crack specifically addressed a timer check that caused the game to freeze after 30 minutes of play in older bypasses.
