So, I have this game that does not allow mapping keyboard keys for player 2. It HAS to be a gamepad. However, p2 does not want to use a gamepad. He wants to use keyboard keys. I have 2 keyboards, so space and other things are not an issue: What I truly wish to do is to map gamepad buttons to keyboard keys, so that when I press my keyboard keys the game believes I am using the gamepad. Or to somehow fool my pc into thinking that one of my keyboards is a gamepad (which I think is not a possible option, but...) I know not how to do any of this, though. Could you help me out here with this?

What game is it?

You could try this http://www.racketboy.com/retro/2007/05/xpadder-use-your-pc-gamepad-instead-of-keyboard.html but instead of plugging in a gamepad, plug in a keyboard and when it says press Dpad up just press W or the up arrow on your keyboard, that sort of thing. If that doesn't work, there's more complicated stuff we can do like finding out what the gamepad stuff is set to and emulating that but it's more complicated and I'd probably have to write a tutorial for you

I already tried xpadder. Pressing keyboard keys does no good. The game is BlazBlue.

Found a solution. Thanks for your attention anyway.

So I just found out xpadder 5.3 is free. This shit is much better than joy2key that I had been using...

Mind explaining what you did for future reference?

VJoy, it creates virtual joysticks with buttons you bind to keyboard keys.
