Hi All, I have the need to benchmark how fast code is running on a CPU emulation. The problem of course I have is the apparant "speed" of an asynchronous emulator is dependent upon how the instructions are synthesised. A JMP can be very quickly calculated as it doesn't affect too many other variables (just the PC). An arithmetic calc can be *long* because flags etc have to be checked /changed. Some questions: 1) does anybody know of a good 6502 benchmarking program that has a good mix of operations.... source code appreciated. 2) which part of the C64 kernal is executed in a endless loop if no interrupt source is active when the machine is booted. I assume the kernal does the normal set-ups, then sits somewhere to wait... if no IRQ, then no cursor flash, but which routine is it in?
