I come to you kindly gentlemen asking for help.
OK... so done reading here and there, but as ever get lost in the esoteric and details and end up further away from an answer than when I start.
In Short:
I want to buy 2 steering wheels for my cab.
Have usb/12V/5V connectors available in my modular CP.
PC inside cab.
Would like to be able to play: MAME games alongside games on: PCSX2; Dolphin; Dreamcast; N64 etc etc
If possible, most features possible, but force feedback would be most sought.
Not too bothered about fidelity to original games (e.g. 360 vs 270). As long as playable.
Is there one recommended wheel for this? Also - pedals? Would I need analogue? USB?
Either any recs or starting pointers would be gratefully received.
Bit late, but a few points:
As stated in the driving cab info thread, 360 degree wheel games that spin endlessly like pole position don't work well with analog wheels which have limited rotation (no matter how far they rotate).
I can't think of any arcade games that allow 2 players on one screen and uses an analog (270 degree) wheel.
Having 2 analog wheels could be of some use on console games, but personally I wouldn't bother with more than one.
If you want the most flexibility, get a Logitech. The profiler software makes it possible to automatically adjust sensitivity, rotation, mappings, etc based on which emulator is running. The power supply is 24v though, so you'd need to add another connector to your modular setup.
There were some really good multiplayer 360 degree wheel games though (Ivan Stewarts Offroad, Sprint, Badlands).
Both groovygamegear and ultimarc offer steering wheels in various sizes for their spinners.
You could have another panel with 2 360 degree wheels, undersized wheels if necessary.
Analog pedals are absolutely necessary for some games. You can get by with digital if you're only going to play casually for the sake of nostalgia and don't really care how well you do. Really need analog ones if you take the game seriously and want to improve your times.
You mentioned ffb being extremely important to you. At this point in time, I don't think any console emulators actually have wheel force feedback fully supported except for maybe PCSX2 (my pc isn't fast enough to run it).
The spreadsheet you linked to lists if a wheel was supported on the original console. I'm hoping it comes in handy at some point in the future when the console emulator devs progress to that point. With a Logitech, you can enable centering feedback for emulators that have no feedback. It helps on the console emulators and MAME.
For N64 emulation, I use Project 64.
