- to my understanding the cyberpatcher is not needed, but a clever hack
- to make the uninplemented functions faster. Someone with deeper
- insight correct me if the following is wrong/inaccurate:
-
- When getting to an unimplemented instruction (like the trigonometric
- floating point functions) the CPU makes an exception, and the
- exceptions handler is responsible for calling the correct routine from
- the 68040.library or someplace else. If the cyberpatcher encounters
- such a case, the instruction in the code is replaced with a direct
- library call, somehow making sure that the usual problems with
- modifying currently running code are avoided.
-
- Thus the overhead of exception handling is avoided, making that
- specific function call much faster the next time.

- P. S. I would also get a WarpEngine, if only I could get one. :-/
