Need for speed - the ROM-patches

[zsolt]

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.

Holy moly Zsolt does it again ! viewtopic.php?f=5&t=2986

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 !
