King of Dragons issues
Hi guys
wanted to play KOD after like a year...
intro is with garbled graphics, wrong colors and textures.
after that follows a screen with vertical lines and the message "System error " and an array of numbers...
I guess it means something is faulty on the PCB and or chips and not dirty contacts (a friend suggested that first..)
will ad pictures later

Re: King of Dragons issues
I guess its the suicide battery - measure the voltage of the battery with a multimeter. If its below 3V its dead.

Re: King of Dragons issues
Ok.... need to check
Battery has been changed end of 2016.
PS: if dead is it possible to revive it somehow?

Re: King of Dragons issues
Have you tried a different A board?
If it is the suicide battery, then they can be revived now.

Re: King of Dragons issues
how do I measure the voltage on the battery?
it has a yellow rubber coating on the edges.
Red pin and black pin goes where to measure?

Re: King of Dragons issues
I could do it. I desuicided my own King of Dragons.
This said, with the amount you'll spend of shipping back and forth, you could just buy yourself an Arduino Uno and LCD shield. The wiring is extremely simple and you don't have to solder anything (well, except a new battery).

Re: King of Dragons issues
It's great to have one around if you have any battery backed CPS gear. Ultimately the coin cells will all die at some point.

Re: King of Dragons issues
That would work too. However, for the price of one you could get the programmer too (with spare change). The batteries are good for 20 years, it's not like you have to do it often.
