Re: Slavemaker Revised Now up to 3.0
Basically, patches in games are the same as patches in clothing. If the original clothing has a hole in it, you apply a patch to fix it. A square inch of fabric might work as a patch for a pair of pants, but you'll be arrested if the only clothing you are wearing is that small patch of cloth on your knee.
As DeMatt said, CMacleod does patches in such a way that they are supposed to overwrite the flawed codes with corrected coding by applying them to the original project (In effect, you are sewing the cloth patch over the hole in your pants as well as the fray fabric surrounding the hole).
