cc65 / apple2 HGR2 linker configuration

Show all headers | View raw

Hi there,

I'm hoping Oliver will see this message :) I've worked a bit on a
linker configuration allowing my program to live from $803 to $3FFF and
use the HGR2 page. The program worked well using HGR1, but its code
can't live entirely between $803 and $1FFF, so it's much bigger than
needed on disk, having 8kB of zeroes on HGR1.

I've managed to make this linker config:
https://github.com/colinleroy/a2tools/blob/master/config/apple2enh-hgr2.cfg

It seems to work good and safe. I checked that the linker errors out if
I put too much code and it crosses the $4000 boundary; I've also
checked that malloc() does the right thing, not touching HGR
page 2 (it starts allocating at $6000 + BSS size + stack size).

I'd love a second opinion though :)

Thanks!
