When CODEX first released The Nonary Games, users immediately reported a critical bug. During the "Novel" (text-heavy) sections of 999, the game would hard-lock or crash to desktop. Worse, Virtue’s Last Reward suffered from save-corruption fears and audio issues during the escape sequences.

The compilation included two masterpieces—Nine Hours, Nine Persons, Nine Doors (999) and Virtue’s Last Reward (VLR)—remastered with high-resolution assets, voice acting for 999, and a streamlined flowchart system. During the "Novel" (text-heavy) sections of 999 ,
