Hi all,
I've got a little question about the ACIA mouse $118 vector.
I've read many things about it and read lot's of source code, but something is never explained :
When I get a mouse paquet : $f8, $f9, $fa or $fb, it gives me the buttons values and then, 2 bytes for the relative X and relative Y values.
All of is is OK and works well in my code except if I move very fast the mouse (in this case, i'm sure deltaX is > 127).
The Atari compendium says : [...] If the movement is greater than can be represented as signed bytes (-128 to 127), multiple packets are sent.
How does this multiple packets works ?
Best regards
Laurent

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
