... may I suggest you do so soon now that a fan translation of the GameBoy Advance title, Mother 1+2, has been released?
Why should you play the version on Mother 1+2 rather than the available-for-eons EarthBound Zero? Here's how Tomato, the person behind this translation (and the translation of Mother 3), recently responded to that question:
"The EarthBound Zero ROM has a good number of changes, censoring and mistakes with plot details and dialog. The text in the EarthBound Zero ROM is also very dry due to limited NES resources. Doing a retranslation with this GBA version allowed for a lot more text, and censoring/changes weren't necessary. The result is a script that should hopefully be more engaging and natural-sounding."
Another reason to skip EarthBound Zero and play the version included on Mother 1+2 instead: The latter includes an "Easy Ring" (found in Ninten's room at the beginning of the game) which can be used by those who hate having to grind for experience and money.
According to Tomato, "this item, when equipped, greatly increases the experience and money you win from enemies while also reducing the amount of random battles. It makes the game much less of a chore, which is one of the main reasons EarthBound fans have a hard time getting into the game."
