My most recent gamebuy is "Pirate Ship Higemaru" arcade PCB... it's an old (1984) Capcom game... a Pengo clone
I think it was only released in Japan and finding pinout for it was impossible so i had to figure out them myself (with some help from Uncletom), the PCB was bought as untested but was working fine after the adapter was done
Here is the pinout:
