Universal Gear Shifter support in MAME discussion
BadMouth:
Transferred the spreadsheet to google docs and I'm working on it there now.
If I understand correctly, if I make it available to anyone, anyone can edit it. ???
If I "publish" it, then nobody can edit it. Anyone use google docs?
Is there any middle ground where everyone can see it while it's still in progress, but only a few can edit it?
(I'd rather make progress on the spreadsheet than spend time figuring out google docs)
Anyways, I came across another interesting driver we can probably learn something from.
In Max RPM (mcr3.c driver), the game was a 4 speed, but the MAME hack is two buttons for SHIFT UP/SHIFT DOWN.
Having a hard time finding info on this one. I may end up with question marks for the number of switches in the shifter.

I think you can set viewing to public and then select who can edit it. I will look later tonight. I haven't used google docs all that much, but it does work well for collaborations like this.

Here is the link to view the spreadsheet so far:
https://spreadsheets.google.com/ccc?key=0ArE1chsgHXQodDd2ckdjLVY3Ujlad2tZWUpteDNtcXc&hl=en&authkey=CIrIhMwE
You have to click on some of the cells to read the contents. (contents will show up in the formula bar at the top)
I used Pot instead of 270 for potentiometer based wheels because it stood out among the 360's more. I'm open to changes.
I'll probably color code it eventually.
It will be a slow process to complete it (I'd rather be doing other things), but I think it will be a good resource when done.

The idea of a blackbox circuit got me thinking about interface..... most of the games on this list use common molex, 2,4,6,...etc. with different
pinouts, so choppin" off plugs or repining plugs will become the new hardware mods. A couple different paths could be taken here, leading to microprocesser,
or RAM. controled by the cpu. Easy enough I guess, but once off the breadboard and protoed, OMG it becomes a project for your local professor. I think
I"d better sit this one out. PS./ SavannahLion, sorry about the X/B thing.

I don't think an external interface would be necessary. The shifter hacks in various drivers already handle everything we want to accomplish.
It's just a matter of seeing how they work and applying that to a standardized way of handling shifter input (says the non-coder).
We have different segments of the user base that want different things. It's important not to alienate any of them.
The preservationists want the way MAME handles shifter input to be representative of the way the game actually functioned.
In addition to being a more accurate record of the game, it will also allow for the original controls to function as they should.
I agree with that.
But if only the original controls work, nobody new is ever going to discover the game or be able to enjoy it.
So an alternative is needed that will cover the bulk of the user base.
Be they keyboard keys, gamepad buttons, paddle shifters, sequential shifters.
They are all just momentary push buttons and would function the same way.
The only real need for a toggle is for someone with an old single switch shifter who wants to use it for a game that had more than one switch in the shifter.
Personally, I think it would be pretty cool to give someone with an old Pole Position setup the option to play california speed on it. :)
I don't think people using the keyboard or gamepad would have a problem with two separate keys for shift up/shift dn instead of one that toggles.
Wanted to say more, but I gotta run, I'm late for work......
