I'm an artist with experience in coding (python, sadly, so this will be a little difficult) and have recently downloaded addmusic, lunarmagic, and a couple sprite and asm editors. Does anyone have anything they can tell me to help me get started?
Honestly, it depends on how ambitious you want to be. For your first hack, I'd keep things fairly simple. Once you're used to the tools, then you can start doing longer and more complex projects. For my hacks, I like to have a structure and foundation already planned out in respect to palettes, graphics, overworld, patches, and so on, but that's probably not necessary for a first hack.
