Thanks I'll make that my next task.

Update time: it worked! Popped in the chip and it actually initialized to the factory defaults on its own. Tested saving different settings and it all works fine now! Only outstanding issue is the input issue but I can deal with that later because it's time to sit down and enjoy the game. Thank...

You know what? I actually ordered 93lc56 chips because that's the model I removed from my board. Will they work or should I get 93c56c chips instead?

And I'm guessing over time the eeprom will eventually become dead and/or empty right?

I appreciate the offer! If I run into any issues I'll reach out but it should be pretty simple, I'll just do the opposite of removing it :)

Wow I just confirmed it myself as well, that's a cool find! So the most likely reason it's freezing when trying to save new settings is because the eeprom was broken? And a broken eeprom is the same as a missing one... interesting I would have assumed if it was at least missing it would go to...

The only settings that aren't default is difficulty (set to Easy) and number of lives (set to 1). It does make sense that it was hard coded and I'd love to take a look but I don't have a programmer. I'm on amazon right now taking a look, this looks like it can do the job right...

I'm terrible with photography let me know if I need to take another snap. The EEPROM that I removed is the one at the top left of the photo at U48.

So I removed the EEPROM but the game settings in test mode are the exact same. I don't see another EEPROM on the board, am I missing something? Could it be stored somewhere else?

Thanks, I'll try and get some time next week to remove it and see what happens.

Just had a thought, if I remove the EEPROM chip the game should be on default settings on boot correct? Is it required to run? This is a PS3-V1 board btw.

The P1 Start and Test didn't work but holding A and Test did bring me to the Maintenance Mode. There's additional entries but unfortunately no option to erase the EPROM. Damn that would have been sweet.

I have a Strikers 1945 II board and when you go to change the game settings and hit yes to confirm it freezes. I'm guessing this is an issue with the EEPROM? The start up diagnostic says OK but not sure how reliable that is. Has anyone encountered this and what's the fix? Solder in a...

Gotcha I'll just have to be careful and do some research beforehand, thanks again for the heads up.

Whoa that's good to know thanks. I'll keep that in mind if I want to buy a dual setup so I'll know I need to buy a regular PSU with it too.

Yo borderline! Thanks man yeah I'll look into grabbing another multimeter next week but in the meantime I won't stress it then if it's regulated. Going to set up a spare monitor and enjoy!

I received my supergun mini recently and it's very cool. This is my first supergun so I'm still learning everything. I have a question regarding the PSU. From my understanding you need to make sure the board measures at 5v and adjust the voltage to correct any deviation. However I don't see any...
