Repost from FW. Make long story short - prototype of mapper 156 in progress. Kickstart 50 loose carts. Ball park price $60 plus shipping.
Yes, i know, a bit costy, but no $2 donor exist, so custom PCB have to be done.
Buzz and Waldog, Buzz and Spinner and KoKo Adventure share the same mapper, so they could be done as well.
Kit or assembled JEDEC compatible PCB without ROM chips could be an option. At moment prototype contain 7 chips common logic plus WRAM chip and 2 ROM chips, so 10 in total.
