0% chance eh? I should play the lottery.

It seems to be tough for some folks to imagine that not all keyboards are created equal.

For the record, the keyboard I am using will only do 8 simultaneous keys. PERIOD.

Also,I was NEVER able to make it generate a ghost key. I repeat, NEVER. However, the masking problem was there.

Now, why I think this is? The encoder has to store in it's memory somewhere what keys you have depressed. Because of the way a keyboard works, it has to "remember" which keys you pressed so it can send a "key off" command when you release it. If you have X number of locations for this temporary data, you get X number of keys. No more, no less.

Say what you want. I have diodes on my switches. The switches still work (so they are not installed backwards) but my keyboard is stil limted to 8 total simultaneous keys.

The chance of failure sounds like a lot more than 0% to me.

: get a bunch of cheap diodes (a bag of a 100 costs a few bucks) and put them in-line with your
: switches (one per switch)

: put one in, if the button doesn't work, flip it
: around.

: unless you mess stuff up, there is 0% chance you
: will see any ghosting again.

: - for those who still think this doesn't work... i don't know what to say...

: : when i press a few buttons on both player one and two's side either no input goes threw or the key press is just not registered.
: : Most games are fine but fighting games are a complete drag because of this.
