Got my aimtraks and have been playing some Mad Dog in Singe and Lethal Enforcers in MAME.
So far I have mixed feelings on the aimtraks. They work great when calibrated... but I'm tall, and anyone else who wants to try them has to recalibrate or turn the aim cursor on, which is not acceptable to me. And... after calibration, if I'm not in the exact spot I was when I calibrated, then the accuracy gets off a bit. For instance, if I calibrate with my arm fully extended, but then get tired during a game and bend my arm, this will throw off my shots by a quarter inch or so. I know, this isn't much, and most people might find it acceptable, but these light gun games are hard enough as it is, and the little bit of precision loss is going to mess you up in the later stages of these games. The last two levels of Lethal Enforcers are not really playable unless you make a concerted effort to stay exactly in your calibration zone, and that little bit of distraction is enough to impact your gameplay.
So after two days I would say that the aimtraks are fine for casual players, but for anyone who wants to play the more difficult stages of these games and play them well (without the cursor turned on as they should be played), they just aren't going to do the job. Perhaps my opinion will change. We'll see.
Anyway, I do have a Singe related question.
For MAME games, in order to get offscreen reload to work with the aimtraks I have to set onscreen trigger = left mouse, and offscreen trigger = left mouse. But for Singe, you can only reload with the right mouse. Does anyone know a way around this? Otherwise I have to go into the aimtrak configuration tool to make the switch whenever I go from Singe->MAME or back again.
I think the "on boarders" reload option in Singe should probably be linked to the left mouse button, then it would be consistent with MAME.
