Hi there,

Issue with an early WPC game.
Before I took my Fun House apart for restoration it was working fine.

I put it back together, take the opportunity to attach a remote battery holder => it's not saving anymore and will always tell me "restored to factory settings".

Looks like I wired it ok, game works fine apart from this, batteries are new and giving 4,8V; continuity is ok all around..
Any idea? Only PITA remaining to call this a finished project!

D1 or D2 could be bad. I don't recall offhand which is used for memory.

It's D2 (checked the traces) but it is fine.
Tested by switching with a MPU from Indiana Jones => Funhouse works fine
(I also tested the Funhouse MPU in the IJ => no boot)

check your solders on the battery pack wires. Also see if you get 4.6 volts out of the battery pack. Seen them not work and needing wires redone them from new. They are cheap and mass produced after all. And use cheap wires in assembly.

Also will it boot after you clear settings restored error? Could have damaged the ram if not. Go nvram and never look back. Batteries of any kind suck.

That (-) terminal solder job doesn't look very complete.

agreed. after resoldering both wires check for power at the wires and at the nvram or asic. easy to do.

Thanks for the answers!

soldering was already redone, no change
Power is fine at the battery endpoint.
Where or the ram and asic?

Nvram might be a solution for sure, just making sure it's nothing else.

will it boot after clearing the battery error?

Check for VCC at D2 as thats the battery diode and d1 is the 5.0 volt diode. Also pin 28 on the ram and every middle pin on each side of the asic. Your D2 could be bad and not allowing the power from the battery pack to reach the ram.

u8 is the ram and u9 is the asic. Cheers
