Try replace 6264.
After the replacement, the same failure
After careful inspection, it is found that the PCB circuit is broken, suspected to be broken by a hard object. After welding, the game can now run normally. Thank you for your help!

I don't see a battery and it looks like VCC and GND shorted from the cell holder.

When I repaired the broken PCB circuit, I removed the battery. No battery was installed when the photo was taken. Now it works fine!
