create alias street_fighter_zero_i -> street_fighter_zero_(game)
The game does not have a number in it - the Japanese title is simply "Street Fighter Zero". The _(game) qualifier is used to separate it from the street fighter zero tag used for the whole (sub-) series.
Also, it's sequels use Arabic numerals and not Roman ones, so the following aliases are also requested:
street_fighter_zero_ii -> street_fighter_zero_2
street_fighter_zero_iii -> street_fighter_zero_3
