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!

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!

Re: Contra J repro on Batman 2?

If you want to use VRC4b mode to run Gradius II RPG, you must use a chip with A17. A17-VRC4 chip's 29 PIN can work properly. I tested it!
