At first I was thinking about going with the Ipac2 since it would handle all my basic needs, but I would need to have an Opti-pac as well for the track ball. Is this the best route to go, or is going with the Mini-pack the best route to take?
The Opti-Pac controls Two trackballs and four spinners (or other mouse-like devices). If you are only concerned with a single trackball, the mini-pac is more cost effective. You should also consider the Opti-Wiz from
www.groovygamegear.com for the trackball and the KeyWiz or GPWiz from them for the buttons and joysticks.
That adds up to 30 inputs, but from how I *think* I understood it is that you can wire joystick 3 to joystick 1, so that you save 4 inputs , hence it truly would only be 26 inputs used up. Am I correct in this understanding?
The KeyWiz has 32 inputs, btw, as does the I-PAC VE.
The drawback to wiring Joystick 3 to Joystick 1 is that if P2 is smart (or Smart---I'm attempting to get by the auto-censor and should be beaten after I re-read the rules--), they can move Joystick 3 to mess up Player 1. The workarounds for this are: Route a switch to swap the gnd connections on and off so that only one of the joysticks is active, or Play as Player 2 is 2P games so you can mess up the other player, but they can't mess up you, or Connect the Joystick up independently (30 inputs as you said), but then you have to map your single joystick games to use different inputs than your dual joystick games.
You can also ditch the two buttons for Joystick 3 and wire these to the same input as P1B1 and P1B2, so you are down to 24 inputs.
I recommend dedicated buttons for pause and escape, which puts you back to 26.
Depending on your frontend, you may want left and right mouse buttons for the trackball. These would connect to the optical interface, but you don't need them for emulation, only for frontend/windows stuff.
For the Trackball, I would need to buy the following to get it all to work correctly I believe, am I correct in thinking this?:
Opti-PAC Interface
Trackball 2 1/4in With Opti-PAC Cable
Trackball Mounting Plate
Depends - You can get Happs or Betson 3" trackballs for around $30 from Menace and others on the B/S/T board here. The Opti-Wiz or mini-pac is an alternative to the Opti-Pac. The mounting plate simplifies installation and would be recommended, but is not essential, depending on your access and knowledge of woodworking tools.
Is the $19 Wiring kit from Ultimarc have all the wiring I would need for the arcade controls? Would I need more, or does it come with more then enough?
No real way to answer that. If "all" you are getting is the kit, it's not a good deal (at least in USA). $19 plus $17 shipping or $36 for:
Crimping Pliers - typically $7.99 to $10 at auto parts or hardware stores.
Approximately 24 yards of wire - (90 ft (30 yrds) of 22AWG wire for $4.99 at Radio Shack) (but not all the different pretty colors).
100 non-insulated QD's - not sure if these are 0.25 or 0.187 - Generally these will run you about $10 at auto parts stores. Peale (member) used to be selling these reasonably, don't know if he still is.
Unknown size and amount of cable ties.
How much wire you need depends on where you mount the encoder and how wide your CP is, but I prefer to buy stuff like this locally.
Thats about it for now. I am sorry if this is all posted somewhere already, if so please give me a link if ya know it. I have tried to make my own 'bookmark list' of everything, along with reading as much as possible, and I think I am begining to have an information overload.
This will help with the information, but not with the overload:
