I need to write a program that runs along with an emulator. The goal of my program is to intercept certain keystrokes before the emulator gets them, and then send the emulator back some different keystrokes.
I want the program to use as few CPU resources as possible, as this will kill the performance of the emulator. I need the program to be active enough to not miss a keypress, but that is it, no more active than that.
I believe the emulator was wrote in VB. Is this an impossible task. Can someone tell me how to do this, or at least point me in the right direction.
I appreciate any help.
