Took me 15 years to catch this: the melody at 0:45 is from Pokemon Stadium! It's the minigame menu song, called "Kids Corner." The slot machine also references the minigame Clefairy Says, where Clefairy points 50 different directions and expects you to memorize them all.
A pair of clowns thought it would be funny to walk into the silent room I was working in and talk non-stop, blasting this at full volume quickly got them to get lost so cheers!
I poured more money down the digital drain playing this game as a kid. (I beated Cynthia at the time.) I blew more money on the slots on this game than the amount of money I used in my entire life. Don't think I'll EVER be able to reach a fraction of that in my life.
I wished this could be played on the villa on the platinum version, sadly isn't, now i look for remixes, of it and sometimes goes back inside in an emulated version just to party there 😂😎
