I think the 68XXX/PPC transition was a bit more abrupt and fink wasn’t around then.  IIRC, for the PPC/Intel transition you had to build two binaries and then put them together with lipo.  I think Xcode/tools will build them together now?

A config file option seems like it might be workable, as this would tend to generate an entire Fink distribution built in a particular way, so one could have a universal, single-architecture, or Rosettafied distribution.

This seems to work much better now.  The older dpkg was also limited in its ability to handle mixed architectures, so maybe a current one will require less patching and mucking around to function.

The best collection of instructions may still be found in the comments at
https://github.com/fink/fink/pull/66#issuecomment-1069568545 and following;
there is also a link to my fink branch as used to install natively on M1.
As far as I recall there is still no straightforward bootstrap available, as I needed
to edit some files like Services.pm manually during installation. One issue is that
`arm` or `arm64` are not registered as official Fink `Architecture`, and either choice
require patching a number of (mostly) perl scripts in various Fink packages.
The other is that the `Triggers` field in the new dpkg/fink created a circular dependency
on the initial install.

That should probably work for 11.x/12. (no idea about Ventura yet), but some problems
keep popping up as Apple is apparently no more keeping the system versions in `sw_vers`
and kernel versions from `uname -r` in sync.

You can also do this in a custom profile of the standard Terminal by setting the shell to run e.g. to
`arch -x86_64 zsh -l`
Once I built a Fink distribution under Rosetta, I could also directy pick one of its shells and
everything from there would run under arch=x86_64.

But for performance I’d always recommend the arm64 builds for any package that can be built
natively (a number have hardware customisations that just cannot be ported to arm without
significant effort).

You can give that branch a try by running
> git pull [email protected]:dhomeier/fink.git dpkg1.16

before ./bootstrap, but as I mentioned, it may still require some manual fixes during bootstrap.

For a starting point on Fink packages on M1  I just pushed the gcc12 port (largely copied from Homebrew) to
https://github.com/fink/fink-distributions/pull/928
