Robotron - sticky joystick signal?
<< < (2/3) > >>
Torc:
just to eliminate the possibitly its 4 bad microswitches, swap em out with ones from the other stick.

You can also run some temporary wiring to eliminate the possibilty its bad wiring. maybe even run it to different blocks, its best to do it in steps. so you can isolate the problem if it goes away.

Hey all - I wanted to bump this thread because I've been playing Robotron lately and the sticky joystick problem is still happening. Here's the thing - I've replaced the Supers with U360s, so it can't be the I-Pac or the cherry switches. If I test the joystick from the WinXP Game Controllers dialog - it functions perfectly. Also when playing the game the problem does not occur until a few levels up (when things start getting hectic). So my guess is it's a problem with mame. Anyone else experience this?

By the way - my new high score; 372k  ;D

I think I've seen this problem a few times, but it's extremely rare, meaning something like 1 in 200 games.  I think I was able to recover pretty easily by monkeying with the controls or something but it was a while ago, so I don't remember.

I have WinXP, minipac, 2 Magstick Plus, Mame 1.09.

The joysticks are probably not the cause since between the two of us, there were at least 2 different sets used.  Since it's happened with IPac/minipac, maybe it's an Ultimarc thing?

Incidentally, I've seen other strange behavior with my Minipac.  I have 2 machines, exactly alike.
- With one machine, using a Windows 2k installation, the minipac seems to drop some joystick input.  Could be related to pressing a single button at the same time.  But on same machine problem does not occur in Linux.
- With other machine, running Win 2k, minipac seems to get completely dropped by the machine, and I have to unplug and replug the USB cable.  This happens quite regularly (once every couple weeks).

PS: Robotron score is 442k on "blue rom" with default settings, which I think is easier than the official configuration.  But then again, I'm handicapped with the Magstick Plus sticks :)

Change your Minipac to use only letter keys, no function keys.

That solved my problems.

Has to be a PC/Encoder issue.  Zero issues here with my mini pac.  Just going to have to play with the setttings a bit.  I am suprised other games are not having some kind of problem..
