Since it's an emulator issue, your question is DOA and explains why no answer was given the last time you asked.
My answer is to ask the author of your emulator.
when i play racing simulations or emulators with more than one controller on a single keyboard, the keys will lock up when i press multiple keys at once. for example, when playing super mario, you press a direction to run plus the button that makes you run fast, then if i try jumping, it wont work because im already using two keys. i am using winxp pro sp2 on an emachines laptop. any help would be appreciated. thanks
