i think u should ask to L6 for multifont patch..
btw my guide is only add language and add font in multifont.. if L6 has already had multifont maybe my guide can work for L6..
i think its almost same with v3x.. about language and font u can edit with motolang editor...
for language.. go at string tab..
to change font.. go at font menu and load font..
to add font.. i think u can follow my guide..
