Title: IPAC 4 and Admin Buttons
Post by: Phunk96 on July 07, 2005, 09:30:12 pm
Hello!

First post and BYOAC Newbie but taking on the adventure!

My question is what about using this to setup admin buttons with the IPAC4:

I know that it is SUPPOSED to be for the keywiz, but why wouldn't it work to press the p1 button and then the button for the enter, pause, esc, etc...

If I get what you are asking: The I-PAC 4 has a built-in "shift" feature.  No additional cables are necessary.

Just use the included WinIPAC software to program the I-PAC. You can select your "shift" button, and assign a second keystroke to every other button.

Won't work because the I-PAC sends shift codes on key release, not key down like the KeyWiz.

You can do what you want with a resistor and capacitor (per button).

See http://www.ultimarc.com/extra_shift.html and the section labelled "I-PAC STEALTH MODE" on this page http://www.mameworld.net/tigerheli/encoder/shiftkeys.htm

Bigger question is why would you need it.

That circuit is designed for the KeyWiz so you can send a shifted input with a single button press.

This is useful if you are using all your 32 inputs and need additional shifted inputs for coin and start.

It would make sense for an I-PAC/2.

Do you really have 56 action inputs and not enough remaining inputs for admin functions that you need one-press shifted admin buttons on your CP?

Thank you for the information.

It isn't that I have that many buttons, but I was just thinking of future expansion to 8 buttons per player instead of just 6.  To which I could leave those inputs open.

I think I am just going to use some of the extra locations for the admin buttons.  I do appreciate your help though.

You do realize that for arcade games you don't even need six, D&D are the only games that use 4 buttons for Players 3 and 4.  All others use 3 or less.

For console emulation (Nintendo 64, Dreamcast), you may well want 8 buttons per player, but IMHO, you would be better adding concealed front USB ports and plugging in gamepads for these games.

Yeah I know that most arcade games don't use that many buttons.

I was just thinking of possibly doing some console emulation possibly in the future.
