Spectral Associates released a program called "RGB Patch" at the  
beginning of 1987 that did a similar thing.  It was a memory-resident  
utility that you'd load up first.  Subsequently, you'd load up your  
assembly-language application (e.g. game) and then run it as per  
normal.  The authors claimed the on-the-fly patching worked with 90%  
of applications, even copy-protected ones.
