Ummm, Yeah that is exactly what I told you after looking at the schematics days ago!
I know, that's what makes it worse, you actually believed it was there and still you supported they undocumented it in MAME. What's your point anyway, are you asserting your words should be taken as some "proof" or "evidence"? How do you not see all my reasoning, as I explained several times and underlined with insults, was based exactly on that one assumption? Read the thread, before you said it we already established there are unused pins that could serve for it.
Anyway, you still have the same opinion? Documenting 'operators manual' (PDF), in software emulator has not only more importance over documenting the PCB, but it also is the reason to undocument functionality of the PCB edge connector?
--- Blah, blah, blah...
I had no idea any arcade enthusiast can dislike this game. I would maybe too, for example, rate Donkey Kong higher than Yie Ar, and many more games would get in front of it on my "top-list", but it just happens to be the game I can always have a go at, while I do not play many of my "favorites" at all. I'd just be bored with Donkey Kong, I could play it long time and that now has opposite effect, when before it was the reason to play the game.
Yie Ar has complexity, you can make up different tactics and chose between many moves. It's quite challenging and only once you master it enough to at least fight with all the opponents in the game, only then you can appreciate its gameplay, plus nice variety of opponents and styles.
