CPS2 problemo

[Stokers]

A couple of days ago I did some routine maintenance on some CPS2 games. Despite having done this many times, Shadow over Mystara now boots to a solid colour

Bloody typical, why couldn't it be Zero 2. Anyway I've checked the battery and it's giving out 3.6v, no issues or anything noteable during the install. I've tried with clamps, without clamps, different motherboards etc and nothing. I'm feeling the next step is to install an infinikey, but is there anything else I could check?

A solid colour usually means it's lost the decryption key, but you should also check all the connection pins between the two halves are not bent

One can use an arduino write the key again. There is memeber on the forum who sells open source de-suicide tools

What exactly did your routine maintenance involve?

Yeh sound like battery gone , as chris said is part of your maintenance to replace battery ? Other thing that can happen (rare but possible) is shorting out battery killing code as well.

As said it can be fixed.

Sorry, to be clear - I was mainly changing the batteries and cleaning the boards and cases.

SOM had an original Maxell battery from 1994, but the game was working fine the week before I swaped it. I didn't check the voltage before I changed it though - so maybe it died on me? It's possible I shorted something in the process, although i'm normally careful to avoid it.

I'll put an infinikey on later and hopefully it will be ok

Infinikey worked like a charm
