As to what I was going to make a more complex request for... I dunno. Some people here make smart-alec detail requests, such as turning enemies into naked Marios with huge flapping penises, just because they think it's funny. Honestly, it isn't. It's just childish, and people who make such detail requests (or even initial smart-alec requests, such as "Pedo Walker") should be suspended, but that's just my opinion.
If you just wanna see really simple changes, such as breast expansions on female characters, then you might as well learn how to hack ROMs yourself. My request for a girls' hack of Sonic 3 & Knuckles is more complex than that. It also requires changing the names wherever they appear, changing the Special Stage sprites, and changing the pictures on the 1up boxes and the signposts. Add to that, I tried to make the aforementioned hack (after someone else gave up), and I couldn't find a single utility that works with Sonic 3 & Knuckles. It's something that I rarely even want to think about.
Anyway, instead of making a hack request, here's a fanfic variation of Super Mario World 2: Yoshi's Island. If you want to create a hack for it, let's talk about it through AIM or MSN, preferably the latter.
And just so you know:
1. Hikari (the female protagonist) is not an OC. She's the main character from Kendo Rage (another Super NES game).
2. I didn't give Hikari a big cone-shaped nose just to be a funnyguy. Just the thought of that actually does arouse me (sexually), as does thoughts of her holding her nose or changing Baby Mario's diaper [chapter 8]. Don't ask why; I don't know or care.
