Hello,
just an update, the allegro branch used is of the 4.4 version. The allegro site
says:
"Allegro 4 is the classic library, whose API is backwards compatible all
the way back
to Allegro 2.0 for DOS/DJGPP (1996). It is no longer actively
developed, but we still
apply patches sent to us by contributors,
mainly to fix minor bugs. Every so often we
will make new releases."
and the most recent 4.X version is 4.4
So the need for keeping track and update the (modified) version used by aseprite
should be relatively easy to meet.
Pedro G.
