I forgot to tell there is 2 games around the globe, they are not yet in mame.
Outer Zone / Not Out Zone. Adventure Canoe
Both avaliable on Taito Egret II mini.
NeoGeo last prototypes, found it but not released to public, thanks to RoU2022. What is Billy Pitt doing it? Searching for trading games? You can´t. If you want them so badly go contact the creators for the mystery games or visit japan. And release the games you already have it from RoU! Japan is no longer partner 100% of SNK, Saudi Arabia take them all out in one big hand. The licence is already death and soon carts in japan will belong in the used store.
