I-PAC to X-BOX project.. help!
AndyWarne:
I am not looking to hack the X-BOX or the video, I just mentioned that part as an intro and then accidentally sent the posting before getting to the real part.
It will be a replacement chip for the I-PAC. I have had many requests for this but now starting to do it, have had mostly people saying that there is little point in doing it! So maybe I'll do something else instead.
Yes the PS/2 is another candidate, just a matter of implementing a different protocol. The X-Box is easier because that is already USB (albeit a strange version of it).
Defining the requirements is the only difficult part as I have never played any console games. Looks like at least two configurations are needed, one that makes the joystick emulate the D-Pad (hey, using the correct terminology already!) and one the Analog thumb sticks (I think mushrooms sounds better!). But then what about buttons? There are not enough on a normal cab to handle the D-Pac directions and the 8 other buttons, if the joystick is handling the analog.

plus the 2 sticks themselves are buttons. Granted, the chances of using each and every one at a time is small, but HALO uses just about all the buttons ;D

Then use both players. The more one looks into X-Box to arcade controls, the less it makes since to have full functionality. To fully emulate one pad with arcade controls, you'd need two analog top fire sticks, one 8 way stick, eight buttons, start and select buttons. So, with a normal cab you'd have to use both players and a third stick (using the player select buttons as start and select).
As far as the buttons being analog, only the triggers are analog. I'm playing with an X-Box controller (S) and the buttons don't slowly move down like a analog button would, only a complete down movement when the pressure is right.
The way I'd set it up with a Street Fighter cab layout, is to have the P1 stick be simulated left analog stick, X Y as the left top two buttons, A B as the left bottom two buttons, and the two right most buttons be selectable between white and black -or- L and R triggers. Then have the P2 stick be selectable between the D-Pad and the right analog stick and two of the buttons be whatever the P1 control isn't (i.e. B&W or L&R) and two more buttons be stick 1 pressed in, and stick 2 pressed in. Of course using the P1 button as start, and the P2 button as select.
The real problem is going to be that most people will probably want to have two players on the same cab. You're going to need to figure out a way to get the I-Pac to simulate two controllers (which may, or may not need two controller contectors), then I'd recommend setting up each player based on the P1 layout I gave.
Do you think you can make it to where it can 'daisy-chain' to an existing J-Pac/I-Pac setup?
As with most anything you can come up with I'm game for beta testing.

Maybe it's just the controller you are using. The action buttons are analog, just like the PS2 controllers.
They don't have a travel, rather respond to increased pressure on the button. Kind of like how a music keyboard equipped with "aftertouch" works.
Here's a link to the MadCatz Xbox controller that shows analog action buttons in the description:
