I was curious and entered your program in the Emu42 emulator and ran it using either ROM A and C. In this way, I was sure to have exactly the same operating conditions. No significant difference. What you are observing is not caused by the software version.

One question: in you first post, you reported that a program of yours was running slower on version A than on version C (+20% running time). Then you reported than your posted program POBR was slower on version C than on version A (now +40% running time). Is that correct?

Very sorry my first post is botched - version A was faster & consistently so. A took 200s & C 280s.

I can hardly believe that I wrote that original error.
