Then successively pressing several keys and remaining down, then all up.

WTF is an LPT port any more these days anyway    :lol

Driver-Man,
I am curious as to why you seem to think that Mame only gets 1 key for each time a USB device gets polled even though as you have already seen, USB devices like the I-PAC transmit all their keypresses in one data packet?

No.

The conclusion is that the USB (EDIT) interfaces available from Ultimarc and Groovy Game Gear work fine, despite the fact that they are not LPT-based.

Everybody who has a cab and has played two player simultaneous games has hit at least 6 keys simultaneously, with the SF and 4-player crews hitting more.

If there were a problem, then I am certain that they, or at least kowal, would have already raised the issue.

The particular topic that you are pursuing has been beaten to death eleventy12! times before, but you want somebody to teach you about it. Read Tiger-Heli's encoder tome. Read the multitude of threads here on the topic (we have had some particularly juicy ones on the topic of USB, PS/2, keyboard and gamepads).

Stop being a twerp and sucking the life out of things because you don't understand.

PS - 60-in-1 boards are illegal!
