U6 is 6264.
U8 is 74LS174.
U9 is GAL16V8.
U11 is 74LS139.
2.I tried to program dump GAL16V8 data, but failed.Except GAL16V8, all the other IC and components I tested were normal.
Therefore, I think GAL16V8 is damaged. If GAL16V8 is damaged, the solution I have in mind is to deduce the equation of GAL16V8 according to the existing circuit and menu program or replace GAL16V8 with multiple 74XXX combinations.So I want you to help me solve this problem.
Thank you very much!
Hello there! I tried to repair my game board and used the chip IC. This makes it easy to replace the chip. I checked your motherboard estimate is 47K and replaced it. Now I burned "8in1_menu.nes" with 27C256 chip. Not running! In DOS with the command "copy /b 8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes 8in1_menu.bin", a new 256K U1.BIN file is created, which can now run, but no menu, then use The command "copy /b 8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes+8in1_menu.nes 8in1_menu.bin", merged into 512K U1.BIN The new file can be run. You are one of the 3 models in the random 8 games. It is different from the 256K running game. 256K can only run 1 game. There is also no menu. You can see the attached photos.

Thank you very much for your help, I fixed it, but I found a problem "6. Ninja Gaiden 3" can start but the screen is black when I start the game! I wonder if this is the case for everyone?

@v5100v5100: Try redumping U3.BIN.

I tried to restore the U3.BIN firmware, the result is still the same, the screen is black. I let the failure video be transmitted to the attachment, please read it, please help me find the cause of the failure. Thank you!

After thinking about it for a week, I suspect that V5100V5100 failed to extract the U3 U4 firmware, so I used the U3.BIN U4.BIN game provided by him to make an error. Unfortunately, my original chip was damaged. Can't test, V5100V5100 hope you see reply Please test it. Thank you!
