https://h0ffman.itch.io/shinobi-neogeo interesting project. There seems to be a problem in mission 2 (which is not stage 2) with the fg layer, but there is still a big part of it which is fully playable anyway with neocd. And added the neogeo version from the roms.zip on the site, strangely the music is different ! It will be named shinobin, just rename roms.zip from the site to shinobin.zip
