There is version/copyright info embedded in the files near offset
$0E00-$0F00, in ASCII with the high bits set. The v4.2 and v6.1 ones
are correct, and "Laser 128EX ROM.bin" is v4.5.

Laser 128 ROM.bin and Laser 128 4 ROM.bin don't contain any version
info the way the other files do.
But both these files are corrupt anyway, since all the high bits seem
to have been stripped from them.

Here is the full info from each of the good files:
