One of the most common issues players face today is the "NVRAM Error" or "Checksum Error" upon booting the game. Because Tekken 3 was released in 1997, the internal batteries powering these original chips are reaching the end of their 20-year lifespan. When the battery dies, the NVRAM loses its ability to hold data. This results in the game resetting to factory defaults every time it is switched off, forcing players to re-unlock the full roster repeatedly. For arcade collectors, the solution usually involves "desoldering" the old chip and installing a new M48T58 or similar RAM module, or performing a "battery mod" to allow for easy cell replacement in the future.
