Good backwards compatibility is a must-have in any "installer" clone. And that has been the problem with all installer clones I tried on classic amiga.

And how would it be better than the 68k version? Look better? New options?

I think it might be better to have 68k installer for backwards compatibility and maybe create a new & better (&different) installer from scratch.

On the other hand, I like programs that don't need installer at all, programs that you can just unarchive and run
