Thanks for the responses!
@GoldenRatio & Dietcoke: I found tons of editors for your own saved files as Goldenratio said, but there currently exist none for other elements of the game. I agree that there must be a way, and that way would require a tool of some sort. Just have to find someone...
@VinceP: I checked Romhacking.net and only found the beautiful 2 player hacked version. (By the way, it actually works!) I have a hex editor, it wasn't very hard to come by. I am able to see all the "hex codes" mind you, but know absolutely nothing about their meaning. So this .ips patcher thing, should I look into it a bit more?
@Esh: I'll wait for some more responses before starting a new game, just in case this UPRC fellow knows anything.
@Goat: I hadn't thought of that. Thank you, this is most likely what I will do.
@Jeff: Hahaha, now you've got me interested.
