I-PAC USB???

[Gromet]

Ok, what functionality do you get out of using the I-PAC in USB instead of just regular PS/2 mode?   What is the prefered method?

Thanks.

None... But what usb gives you (plug-n play mainly).  Both work GREAT!  

Are you using dos?  If not, it's probably worth getting the USB version.  It can be nice to unplug it while the cab is on.

USB is limited to something like 14 simutaneous keypresses and some people have had problems with it if USB keyboard support was enabled in the BIOS, otherwise, it works fine.

How could you possibly get 14 simultaneous key presses?  Two players, both moving diagonally and hitting two buttons, would only be 8.

Two caffiene-addled Majohng players, with authentic control panels?

Four people playing Turtles In Time at once, and all trying to move diagonally and perform their special "super whack" moves (A + B together) while inserting coins with the nearest convenient third appendage?  Simultaneously?


1, 2, 4, 8, 9, 10, 12, 14, 16, 17, 18, 19, 20.

I'd use PS2 port just to see that happen!

Using the PS/2 to USB adapter supplied with my JPAC, I personally found I was getting interference on my arcade screen that didnt exist when I was connected thru PS/2.

Very minor, but still noticed... thus annoying.

anyone else notice this?

I believe in USB mode the IPAC uses keyrepeat, whereas in PS/2 mode it doesn't.

Not sure if this has many advantages, but I was thinking of adding an option to take advantage of this in my FE (Keyrepeat = slightly less code to execute).

But on a 2-player panel I would think 14 simultaneous inputs is enough.  The most I can think of using is 2 players hitting a diagonal & 3 buttons each which makes 10.

I agree, it's not a practical limitation, but it does exist in USB and not in PS/2 mode so I thought I'd mention it.
