Guru has an update on his website. It seems he was able to get the Woodpecker ROMs from the board I sent him! Woodpecker was added to MAME 0.88u4!
I have now officially made my contribution to the cause! Now to go find 0.88u4...
For those that don't remember, a friend of mine had this Woodpecker in a generic cabinet in his Mom's basement for the last 20 years. It hasn't worked for a while, so he asked me to mame the cabinet. I got to keep the board and couldn't understand why I couldn't find it in MAME. When I mentioned it here, I was contacted by the 'authorites' who asked me to send it off to Guru. Needless to say, he worked his magic and another game is added to the list!
