A lot of my samples are pillaged from other people's modules. I've learned basically everything I know about Furnace from downloading project files in the Furnace Discord and studying the techniques that people used. For the SNES specifically, you can find a ton of samples on HVB's guide: https://samplemance.rs/snesguide/samples/repo/
For future goals, I'm working on an NES album currently, though because I don't have a jam to get me on the grind, it probably won't be out for a while. Generally just planning on making whatever I feel like at any given time. Will post anything I make on my YouTube channel: https://www.youtube.com/@bin6485
Looking forward to seeing what you make in the future too!
