| Successful game port hack |
| (1/1) |
| Rocky:
After trying several different potentiometers on my home made wheel (spyhunter functionality), I think I finally got the right value. My wheel has just under 180 degrees of motion. I originally used 120k and 150k pots. By raising the sensitivity in MAME, I could get reasonable play in Spy Hunter and Outrun, but I knew I wasn't getting full left or right. I ordered 250k pots about 5 months ago and finally put in the steering pot today. Wow! It's freekin awesome! At full left the wheel reads 0 Ohms At full left the wheel reads 151K Ohms Center is 69K (This might help someone who is making your own game port controller) Other information: I used this as my inspiration to build the wheel: http://www.monmouth.com/~lw4750/ I hacked into a game port connector and just hooked up the X and Y axis, no buttons (It has been incorrectly reported that you need at least one button to calibrate a joystick in Win98se -- you can just click the mouse on next) Woohoo! I can finally stay on the road in Outrun on the merging lanes! Rocky |

Sounds good. I used 60k resistors for my gameport mod and it worked fine -- 0k left, 60k middle, 120k right. Used a pot is a good idea though! This site has tons of joystick related info, I used it for my mod. http://www.epanorama.net/documents/joystick/pc_circuits.html |
