I read that thread:
Arcade Driving Cab / Steering Wheel / Racing / Information- last update
but did not understand all to be honestly.
For my understanding I only can play Daytona 1 OR 2......Sega Rally 1 OR 2...but not both on one system???
What part made you think that?
They are playable on different emulators, but can be on the same computer.
Sega Rally 2 is playable on Supermodel emulator, but has some annoying graphics glitches.
Of the games you listed, Sega Rally 3 and Ford Racing aren't supported by any emulator.
Winding Heat still has some glitches in MAME.
Do I need 2 Computers (no problem if so) and do I link them via network-cable?
How strong should the CPU´s be....Motherboards, RAM´s and so on....?
For most things. Only a limited number of emulated games are linkable.
Look in the Model 2 setup guide stickied at the top of this forums on how it's done.
The model 2 games and Virtua Racing in MAME(using a custom build) are about it.
The next version of Supermodel (Model 3 emulator) will have networking, but it probably won't be released until April.
Keep your expectations low. Most people experience flickering opponents cars.
I'm yet to set up networking, but am building a twin setup, so I'll be getting to it sometime.
This will give you some idea of what processor you'll need.
http://forum.arcadecontrols.com/index.php/topic,130988.msg1342049.html#msg1342049 If you want to play stuff newer than the original Daytona or play Ridge Racer using MAME, you'll need a top shelf processor and video card. If you're only worried about Daytona and older, you can get away with a lot less.
Of course I want Force Feedback (who not? ) and I would like to use the original FFB-motors like that guy here in the forum did....as far as that cabinet got FFB.
From what I found out it got it, and when the motors are commercial-grade and as huge as in an daytona USA than I dont want to change them against a small consumer-grade product.
Is that the right cabinet for my plans?
According to the manual I looked at online, Winding Heat didn't have force feedback. It just had a centering spring.
If you find this stuff confusing, your best bet would probably be to mount a PC force feedback wheel (whole) in the dash.
Browse the Links to Driving Cab Projects thread and you'll see a few like that, including my old cab.
