This is a quick repair blog to document the fix for the “EEPROM Error 0200” issue our good friend Marc Bell of http://gamethesystem.co was having with his Splatterhouse PCB.
DIP switch 1 is the test DIP switch. I turned it on and powered up the PCB to be greeted with this:
Doing some research online I found quite a few repair blogs that mentioned this can be caused by this EEPROM at location U1 on the smaller of the two PCBs. This EEPROM is used to store soft DIP data:
To fix it, you need to:
- Remove the chip and erase it with an EEPROM burner (or overwrite it with a blank file – you can dump it and delete the contents of the dumped file to make a blank file that you can write back to the EEPROM).
- Put the EEPROM back in the socket.
- Turn on the test DIP (DIP 1).
- Power on the game.
- The game will prompt to press the fire button to re-initialise the game settings. Press fire.
- Once the EEPROM is re-initialised you will see the soft DIP settings on screen. For me these were upside down and I had to change the “screen flip” setting. You can also set up attract mode audio, coin settings and difficulty.
- When you are happy with the settings, to save them you need to turn off the test DIP switch with the power still on. If you do not do this then the settings will not be saved and next time you power on the game you need to start the process again.
- Once you switch the test DIP off you should be greeted with the game’s attract mode and you are ready to play!
I hope this helps someone faced with the same issue!
