If people use the multicore cd to install tinycore, they come to "Select File for tinycore." Yet in the multicore cd it is always in the same place.
During installation, have the option: If you want to install a different version than the one you are running, click here (or something similar).
If they don't select a different version.
Automatically mount the partition tinycore is being run from.
Have the installer automatically default to the location of tinycore.gz (or microcore.gz), and use it for installation.
If the user does want to install a different version, let them select the location.
I have not checked it out, but look at the same issue with grub4dos.gz.
