It already handles 2 trackballs and 4 spinners. Do you really want more? Are there any games that use more? (but good question)
I believe thats 2 trackballs ** OR ** 4 spinners.
There are games like rampart that use 3 trackballs.
Plus atari football and atari soccer can have 4 trackballs.
Also, because I have 8 optical inputs... it would be helpfull.
dual trackballs
dual spinners
dual opto rotary joys
dual supersprint wheels
Mame:analog+ can track all eight "mice", but people can only use one "mouse" per player, so there is a limit of four mice in use at a time. (Actually, one mouse axis per player axis, with two player axes results in two half mice, so I guess all mice can be used at a time, but who cares about the details.
)
If you have other USB devices plugged in ... like other use mice or trackballs..ect, will they also interfere?
No problems here. I can have one USB ipac (with two trackballs), one happs USB trackball interface, one PC trackball, one USB gamepad, and one USB steering wheel with no problems, besides my computer desk covered with input devices.
So I am able to "play" the four trackball games. I put quotes around the play because I can't fit that many people around my computer, so one person has to control two trackballs. But it works (winMe, mame:analog+ .62 and .61)
If you hot swap devices, will you have any probs?
(ie - need to reboot)
Nope. You can plug/unplug either the USB end, or a trackball from the ipac with little problems. There is the time it takes windows to load the drivers if you plug/unplug the USB end. Also, don't plug/unplug the USB end while playing a game, or analog+ will lose track of the trackballs and the input will be messed up. Just exit and restart the game to fix it. No problems if you plug/unplug the trackball on the ipac side, though.
