[HOW TO] Play games with multiple keyboard press exceeding limit

Well friends, my friend and me were playing Street Fighter Alpha 3 inside a PlayStation emulator on our PC. But the problem arose was if one pressed more than 3-4 keys at a single time, other could not hit any special powers. Then we just stopped playing that and start a search for it. We didn’t find any software related solution like any tweak to increase the number of key pressed. Though we found some information in different areas and made a kind of solution.
