Went, I'm just going to rant a bit on your profile about a puzzle in Mario & Luigi: Superstar Saga. I'm at the part where I have to escort Princess Peach through Teehee Valley. It's just so difficult to keep her in sight and press the right buttons to get the order of the Bros. right and make sure that I'm on the correct option for what I need to do.
It's just one little section that's ruining my fun. :[ I took a break from the game to see if that will help. Maybe some words of encouragement from you will also do the trick.
Well, whoever wrote that pronunciation suffered from "seseo", which is pronouncing c and z as a s. It is NOT the correct pronunciation, although is absolutely commonplace in South American and South Spanish dialects.
Z has a proper sound that is quite different from s so it should be "bahn-zo". But with an even softer z sound that the usual in English, which is closer to s than to Spanish z. It's hard to explain, but certainly those saying "Bone-so" are suffering from seseo. Specially if the guy is supposed to be from Madrid. We are unable to pronounce d's at the end of a word (such as in: Madrid), but we certainly can pronounce a z properly. Did Not Do The Research.
