If you are a programmer looking at the ROMfs, the fixed files are located in: /romfs/scripts/ui/missions/ Look for the file mission_helpers.lua (CRC32: F1E2D3C4 ). That is the signature of a fixed ROM.
In response to the community feedback, the developers and Sega, the game's publisher, worked to release patches and updates aimed at fixing the ROM issues and other technical problems. These patches have been crucial in stabilizing the game and ensuring that players can enjoy Sonic Origins Plus without significant interruptions.
