usb keyboard and buffer

Is there any way to increase keyboard buffer size ? Cuz i hate jamming keys when i play with my bro in some oldschool games such as MK, or even it happens sometimes in quake, (when i starfe in air, keeping pressed crouch butoon, i can change a weapon). I hate when sth is not working as it should. Please help me, i looking for help on many forums and no one seems to know enough.

that way does NOT work

I hope there is someone in Tom's Hardware who knows how it works exacly and how to solve that, may be Tom himself

It's present on any keyboard notedicated for gaming, cuz each keyboard have a small chip witch scans the matrix for pressed keys. In most cases buffer of that chip can remeber 4 buttons, 4x2 Bytes. Try pressing wsa together, and then press c. That buffer is independent from OS buffer. As i know, Razer Tarantula has non standard chip, it allow to press up to 10 buttons.

Anyway, i solved splitscreen gaming by useing two keyboards at once, one usb and one ps2
