Hi Siggi,
Over the past few months I did not deal with this problem, but I spent a lot of time writing and testing new arithmetic routines.
They are now faster and a bit smaller
coming soon.
Regards,
Zsolt

Hi,
I built a new ROM image using the
renewed arithmetics and a little patch in the 'NEXT' routine.
- ClckFreq.p (performed on sz81)
- SG81F_BN.png (4.7 KiB) Viewed 5771 times
Enjoy,
Zsolt

This doesn't just surpass the old record it absolutely ate it, swallowed it, and spat it out, before trampling all over it ! almost half as fast again !
