This is not an arcade manual. It is a shinobi rom. If you look at the contents of the shinobi rom that I have, it has some of these files including shinobi.a1 the contents of which is identical to the shinobi.a1 in your shinobi.zip file.
Not sure what version of rom or how old it is, but I don't think its the latest.
ADDITION:
Looks like a rom version prior to .36 beta 2 as the names of the drivers in that rom were what you have prior to then. Below you can see all your file names and when they were changed in beta 2.
