Our collaborator Andrew Morgan questionned the precision of the Amiga mouse firmware when used with a paint software like DPaint IV. Sometimes, the mouse was jumping too fast between pixels in an erratic way. We analysed the situation and found out that the way of reading both axis, in polling mode, was infact innacurate.

We rebuilt a new software that take advantage of the hardware interrupts of the CPU chip.

This gives a near-perfect operation, even with more sensitive trackballs or “laser type” mouses. This also made us update the whole fork build for other mouses like the Atari ST and the Mac Mouse. All theses new firmwares are available for download in our download section.
