Tiger-Heli:
Okay, everyone listen carefully to my responses here, because they will tell you a lot about the product (and keyboard input devices in general).

Simply play-testing it is unlikely to reveal a problem. You have to have a certain combination of three keys pressed to generate a fourth ghost key. And that isn't nearly as much of a problem as key blocking. Let's say that you press Player 1 buttons 1, 2, and 3 and the unit generates a "ghost" Y keypress. But Y isn't used in your emulator. . . Will you ever notice it? No! Is the encoder working the way you would want it to? No!

I haven't seen their schematic, but if it's properly laid out, I'm not at all surprised that it is working. The KB16 encoder that I tested would support 8 simultaneous inputs IF you picked alternating connections. Assuming the KB32 is the same, we have 16 available simultaneous inputs, and since a joystick can't be up and down at the same time, we allow them to ghost, giving us two more inputs per joystick, or 20 inputs, or a 2-player, 6-button layout. Of course you could also do this with most keyboard hacks. . .
Nothing yet has convinced me to change my opinion of it. . .

Please do. I think it will work fine until you add coin and start buttons to the mix, and even then, it would only occasionally have problems.

Won't arque too much with you on that either. $12.50 shipped for essentially a one-time programmable 20 action key plus 12 ghosting key encoder isn't a bad deal. It's the website adds for $29.95 plus shipping for the same encoder compared to $23 plus shipping for a KeyWiz Eco no-solder with 32 non-ghosting input and full configuration software that I have a problem with.

I notice that his new auctions have reserves ... guess he got tired of letting them go cheap.
Cheers.

Heh, yeah I noticed that too.

Maybe I'm not dexterous enough to cause ghosting. ;) I'll let a kid try it out....they can mash every button at the same time somehow!
--- End quote ---
Like I said, ghosting can only happen when you have 3 buttons pressed at the same time, and if the encoder sends a ghosted start button for a player that either is currently playing or has no credits, how would you know???
BTW, if you get curious or ambitious, check my page on the KB32 above and run the tests I recommend, I'd be interested to know if what I wrote was accurate.

TOKN KB32
Resurrecting and older thread. I have been discussing my KB32 with Tiger-heli in PM's and it seems that I have been fortunate enough to get one of the newer boards. I am reposting the picture of the board and you will see that this is the '32L' version. The diodes are already on the board.
With a little help form Tiger-Heli I mapped out the matrix for both players but have yet to see if I will have any ghosting issues. The thought was that I should not with the diodes already in place. I have read allot of hard knocks on this product but from my research it looks as if these concerns were trying to be addressed in this unit. I almost wish I had found a few more for the price I got it for well over a year ago!
