Playstation/PS2 gamepad encoder?

Pages: << < (4/5) > >>

Timstuff:

While I could technically skip the keyboard encoder altogether and just use a playstation USB adapter, there are some compelling reasons not to.  Namely that I wouldn't be able to wire up the escape and pause keys in MAME, or wire up the coin doors to give me virtual credits. A playstation pad has 10 buttons, but my panel will have 11 on each side, three of which will corrospond with keyboard key functions rather than joystick buttons. So the most logical thing to me it seems would be to buy a Keywiz Max and 2 really cheap playstation controllers, and either wire the Keywiz Max and PS pads to a set of Molex connectors that have connect to the buttons simeltaniousely, or wire the controls so that I can open up the panel and flip a switch to go between them. The former option sounds more convinient, but I'm not an electrician so I don't know if it's safe to be wiring three wires together for a do-it-yourself Y connection. If this concept of wiring both the keyboard encoder wires and playstation encoder wires to the same set of wires that are connected to the arcade controls is safe and will work, I think I'd be happy going with it.

Also, Lik-Sang and several other sites sell adapters that connect playstation controllers to Gamecube and Xbox. If my plans for making my controls Playstation compatable will work, I could also use my cabinet with GCN and Xbox just by buying a few adapters! :)

I don't completely follow what you're trying to accomplish.

Haven't studied this in depth - 10 buttons plus joystick, how many were you wanting for action buttons, and how many are left?

Ermmmn, why not?  Reconfigure MAME so Escape is Joy1Button10, Pause is Joy1Button9, Coin 1 is Joy2Button9, Coin 2 is Joy2 Button10.  Switch on coin door goes to pad input for Joy2Button9, etc.

I think you would be okay, especially if the playstation pad uses common ground, and almost certainly if the PS was off when the MAME computer was on, and vice versa.  You might want to check with someone else, though.

Or with MAME with the USB adapters - what am I missing?

Timstuff:

For my controls, I'm going to have 8 action buttons per player, player 1 and 2 start buttons, an exit button, a pause button, and the coin door will be wired to the control interface for coin ups on player 1 and 2. If I was only using 7 or 6 action buttons, I'd have enough buttons on the PS1 controller to still have coin ups. But because I want to have plenty of buttons to go around, I don't think I'm gonna get out of using a keyboard encoder.

It could still be done.  For PS2 you will want 8 action buttons, but for MAME you won't.  You could wire the microswitch on the coin door and P1 and P2 Button 8 to the same input.  Of course, pressing the Button 8 switch would now also deposit coins in mame, and pressing the coin buttons would activate button 8 in the PS games.

You could also hack a third PS2 pad and have Joypad3 Button1 is Coin1, Joypad3 Button2 is Coin 2.

You could also get the solderless version of the KeyWiz Eco, which is $11 less than the MAX and no more work than hacking a PS2 pad.

Just giving you options . . .

Other options include using a Ipac VE for the utility buttons only in mame then 2 PS2 joystick hacks with the USB convertors for the action buttons.
