Strangest problem with my KeyWiz

[SirPeale]

I only really started using my KeyWiz over the last week, as I finally got sick of BUILDING the cab, instead of PLAYING the cab.  So, I threw it all together.  It's in no way done, but it's playable.

Anyway, I've noticed on some games I can't insert a coin.  I've got it wired up correctly, this I know.  I can insert a coin in many games.  But...let's say I start a game of 'Space Invaders.'  I can't coin up.  I can do it if I hook up a real keyboard, but not with the KeyWiz.

There were several other games I noted that did the same thing, but this is the last one that I remember doing it.

I did check to make sure the keys are mapped correctly for this game.  They are.

What could be going on?

Slight update: I can now use that slot.  I tried another game earlier (of course now that I'm in front of the computer, I forget which one) and it did the same thing, but allowed me to use the other slot (6)

So I went back to Space Invaders, and tried it.  Nothing.  Then I tried slot 1 (5) and it worked.  Very strange.

I had one input that just plain didn't work. Also, I've decided I'm not a big fan of the function+stick-right or function+stick-left to change between keysets. Ends up happening way too often, or at least for me. But otherwise, it worked exactly as I had hoped.

Now I just have to figure out if the input latency is coming from the Keywiz or from MAME itself. You don't notice it in most games, but you sure do in fighters.

I think I may have figured it out; I think I wired the coin slots backwards.  A lot of games, although they had two coin slots, they were wired up to the same input.  I could be wrong about that, but I switched the wires, and it seems to be working okay now.

Suggestion:  If you run across a game with only one coin slot input, set MAME so Coin 1 is "5 or 6" through the ctlr.ini or Input This Game menu.  Now either coin button will work with the game.

If there is one thing the KeyWiz is, it's flexible (not literally )

If you are using the custom set, you can disable the on-the-fly switching by hooking up the ground (COM) of the P1LEFT microswitch to the NC contact of your Shazaaam! microswitch.  That way, when Shazaaam! is pressed, no ground signal can make it to left and therefore, no switching .  This also works if you are using the default set, just use the P1RIGHT instead of left.

If anyone needs further clarification on this, feel free to PM or email me.

Also, since the main design philosophy of the KeyWiz is based pretty strictly on performance, any latency would almost certainly be due to software issues.  Latency issues can be caused by a number of factors including poor input handling, OS issues or insufficient processor speed for the particular program in question.  All of which are independant from the KeyWiz.  Just an FYI

Just wanted to make note  that Randy has replied to me privately, and was very helpful. He offered me some diagnostic tips, and even made a very generous offer in the case that the board is in fact defective. Thanks Randy, and I'll get back to you soon. I continue to recommend your product to everyone I speak with
