I don't doubt that the GBA version is inferior, just letting you know that they did carry it on to a newer console. Apparently it is good, but I haven't played either so I wouldn't know.
GBA rocks though, I am playing the new Mario and Luigi RPG, it is good fun.
on a side note, Mark just has to earn $30,000 in the UK to get AUS$100,000 \m/
so if Mark made $300,000 in the UK and came back to Australia with all of it in tact, he would be a millionaire here!!
