I think they will be difficult becuause they do not have the help of having Greek letters to help
Linier B is much more dificult as they have to start from the begging as it appears to not be written in Greek.
Remember even with the Rosetta storne it took q long time
There is a very fine Etruscan museum in the city of Volterra (which has an intact Etruscan-era arch in the city wall). The Villa Giulia Museum in Rome has some very nice Etruscan sculptures. The archaeological museum in Perugia has one of the longest Etruscan texts (on a stele).
The Linear B system is completely different from the later Greek alphabet, but since 1952 the values of most of the symbols are known so the texts can be more or less read...It is an early form of Greek (several hundred years earlier than Homer). Linear A is a similar syllabary used for a non-Greek language which has not been deciphered.
