Heya Joshie, welcome to PC! <33
Look around
Emulation and I'm sure you'll find some neat things that can help you out with learning to make a ROM. The section is big so there are a lot of regulars, meaning it probably won't be very hard to get help if you need it. Unfortunately I'm not the best person to go to for that; otherwise I would've loved to volunteer and help you out a bit. But I'm sure with some dedication you'll get there fairly quickly. Good luck with everything, including creating vectors! I'd like to learn to make good vectors myself, especially since they're great for logos and all since there is no issue with quality loss. Would help out a lot for my college major. D:
I'm glad to hear you have so many interests though, that always makes your experience on a forum as large as this one better! On top of our myriads of Pokemon gaming sections, we also have a
Fanfiction & Writing section plus an area of the site dedicated to
video games. So yeah... pretty diverse forum, if I do say so myself. Hopefully you find that section you click with soon here if you haven't already! Might take longer for some than others, but PC is one of those places that's really appealing visually (thanks to the awesome skins) and has a lot of people to discuss things with, making it hard to get bored. For me and many others at least, haha!
Have a good time here and see you around! :D
