My official MAME output wip thread.
Xiaou2:
If it helps...
Race Drivin / Hard Drivin use a special '10 turn pot'. It turns much more than
a typical pot.
The steering wheel itself can turn like 6 full rotations.
It used a pressure sensitive pad of some sort, for the brake.
Standard pot for the gas.
2 pots for the shifter unit. (x & y) ((sitdown only))
The Seat has a pot under it, so it can read where the seat is. It also
has a very powerful electro-magnet, which locks the seat down in place.
Actually, I believe there is also a shifter lock down coil as well.
(I think it was to make it hard to impossible to shift unless using the clutch.)
The motor is HUGE. Its like a dryer motor, and weighs like 50lbs.
The force feedback lever can be set in the test menu. At full strength, it can
almost rip your arms off heh
There is a calibration for all the controls in the test menu.
Controls can be disabled in the test menu.
I worked on this game a lot in both the arcade, and for a friend who has
two of them in his shop linked up.
Howard_Casto:
I'll look into it once I get the y-board squared away.
I've pretty well figured out all the data at this point and I have all of my functions in place I'm just having trouble getting the exact ranges, especially on power drift because the debug menu errors out and won't give me any feedback.
I think I've gotten it as close as I can though so I'll be buttoning the driver file up pretty soon.
Xiaou2:
I cant confirm this yet, but I have a feeling that powerdrift had both a
one-way motor for shaking the steering wheel AND had a cabinet tilt motor(s?).
The shaker motor may have had a speed control on it as well.
I believe the cabinet motor was always one speed, because I believe it used
a worm drive, which is slow in nature, but very powerful, so wont slip no matter
how much mass is in the seat.
Howard_Casto:
Yeah I already knew that much, I just couldn't figure out if it used one or two motors for tilting. I'm pretty sure it's just one now.
It's much more primative than I would have thought though. It's a 7 position motor... that's it! So you have centered and 3 stages of tilt in either direction.
Now gloc and strike fighter have 27 stages of tilt in each ram (supposedly 32, but in practial terms you only get 27) which sounds more like it.
I wish I could get the r360 version working. Somebody mapped the pitch and roll outputs to inputs and I'm having trouble reading them. On top of that one of them isn't hooked up to the right address anyway. I could probably fix it, but I'd have to modify mame's address maps and I'm not super comfortable with that.
Howard_Casto:
Ok, sega y board is done!
I've got a few comments to add for documentation purposes, but I'm ready to take on another driver. I'll look at the harddrivin driver next since I was asked. :D
