I was just wondering if there is any chance of getting support in DOSBox for the LPT Joystick adaptor used in the game Slicks 'n' Slides. I registered this game YONKS ago because we used to play it in school every lunchtime and I'm now creating a multi-emulator "console" using a set of USB joypad adaptors and a TV Out to play all the games that I used to play.
It comes with a diagram (attached) which basically uses a different pin on the LPT port for each joypad movement (up, down, left, right, fire) so allowing all four players to simultaneously move diagonally and fire without interfering with each other. The diagram contains no electronics other than protective diodes so emulating it would simply be a matter of "setting" the bits on the "virtual" LPT data input pins (and possibly things like the paper out pins etc.) to correspond to the controller buttons.
Would it be possible and/or likely to see support for this sort of input system? I know joystick support in general is limited currently but it looks like an interesting, simple project for someone with programming ability, as well as a good test of any joystick input system - mapping up to four "real" USB or gameport joysticks (via SDL/DirectInput one would assume) to "virtual" LPT pin inputs. Also, I don't think that Slicks was the ONLY game to use this kind of adaptor.
I've attached the ASCII circuit diagram from the game (although you may have trouble reading it in "modern" Windows editors as the character set makes it awkward - an old DOS editor like EDIT does the trick).
Thanks
