| Emulating a 4-way joystick |

| JZSlenker:
I know I know, lots of people have already talked about this but I have one more question. I am fully aware that I can (or could) have put a third joystick in that is an actual 4-way joystick, or I could change the restrictor, or I could buy ultimarcs joystick. At this point I'm not going to do either of those things. My question is.... Somewhere I had read the following for a way to make 8-way sticks behave better on 4-way games. ... map your inputs as such ultimately: UP = UP NOT UP/LEFT NOT UP/RIGHT DOWN = DOWN NOT DOWN/LEFT NOT DOWN/RIGHT etc. the end result, the game only accepts the "pure" four directions. if you push diagonal, you get no response. Now what I did was to map things as follows UP=UP not LEFT or UP not RIGHT DOWN = DOWN not LEFT or DOWN not RIGHT etc etc This DOES make a marked difference in controllability.! Would it be better to map it as the post suggests using the same time wording, or is the way I've done it better? Thanks |

Are you using a keyboard encoder, or a gamepad encoder? (Mame does extra stuff with gamepad encoders.) What game(s) have you tested? (Games handle diagonals differently.) Logically, what you have is the same as Up = Up. Why: Your map is Up = (Up not Left) or (Up not Right). If you press up-left, mame looks at the map and checks if it is (Up not Left); it fails this one, so mame checks the next part. Is Up-Left (Up not right)? Yup it is, so mame accepts Up-Left as Up. Mirror for Up-right, etc. The only difference I can see between your map and the simplified Up=Up is that mame has to do some more logical steps sometimes. If you want to have diagonals ignored, it should be mapped: Up = Up not Left not Right. Down = Down not Left not Right etc If you mapped exactly as you guoted, no directions would work, I think. |

You are right, mapped as quoted nothing works. UP=UP NOT LEFT NOT RIGHT works great. I'm using an I-Pac and testing on games like Donkey Kong, and MsPacman Thanks for the reply. |

I think it would be more challenging for a game like pacman just to have four push buttons instead of a joystick. |
| JZSlenker:
So for a game like pacman to disable diagonals for both joysticks I can do... UP=UP OR R NOT LEFT NOT RIGHT NOT D NOT G LEFT=LEFT OR D NOT UP NOT DOWN NOT R NOT F etc etc |
