Dang, I knew I forgot something (I was planning to test Terminator 2.) I'll try it later.
I did get it in a gun shell. I put it in an old Dreamcast lightgun. A little bigger than an arcade gun, but it'll do for now.
I hooked it up to my cabinet, temporarily put up the LED board, and configured everything to work. I tried to hook buttons up to the other connections (P1 through P5), so I could coin-up and start without having to be right at my machine. Unfortunately, the pins don't seem to work. I do have them set in the configuration software (and sent to the Gun PCB), and evern tried shorting the inputs to ground with a small wire, but they don't do anything, even in the gamepad test. I'll check my settings, as I may have done something wrong. If it is a problem on the Ultimarc end, I'm sure a simple software update is all that's needed.
And now, the part that everyone is asking about: accuracy at different angles and heights. I tried this using Area 51. I calibrated the AimTrak, but I never adjusted from the Area 51 "in-game" (service menu) settings. Got through the first part with ease.
Next, the height. I sat down on the floor (same place as I was standing). For reference, I'm roughly 5'7". Sitting on the floor, shooting up at an angle, and not recalibrating, I still did pretty good. So I don't think height is going to be much of a problem.
I tried off to the right of the screen at almost a 45 degree angle. Now I has having difficulty hitting things. In reality, nobody would seriously play from that angle, but if the angle did affect anything, a quick recalibration might be in order. I'll try to do more testing in this area.
Finally, distance from screen. I tried standing as far back from the screen as I could (a wall prevented me from going further. I did still have some cord left). So distance went from 5 ft from the screen to 9 ft. (still no recalibration, and at the same angle as when I started.) Things got hard to hit again. I might go back to see if the cursor lines up at this distance, since by this time in my test, I was in the middle of level 2, so it naturally was more difficult. Plus, I was trying to shoot things on a 21 inch screen from 9 feet away.
So, at least to me, everything seems to work as expected, given the used technology. Take into account I'm a casual gamer. Someone with actual weapons training may find small variences I didn't even notice. But for casual gamers, there's enough leeway that you won't have to put an X in tape on the carpet where the player must exactly stand, and height doesn't seem to be a major factor at all.
Perhaps a Youtube video could be made, when I have the time.
