That's awesome! I've been wanting to get into NES dev myself. It seems like it could be fun.
I'm mostly just a dirty script writer lol. Game development seems like a lot of work - I always wear myself out just thinking about the endless branches of logic and things to consider... but I really want to make a game in the style of Shadowgate etc. for the NES, and every year I get somewhat closer to actually trying. I have no experience with ASM, but I do have just enough autism to hyperfocus like a beast on things that interest me.
I bought NESMaker a few years ago, it doesn't quite seem to do what I'm after, but I'm thinking may be I can make something small with that as a starting point, then kinda work backwards to see how it does what it does under the hood and move over to 8bitworkshop when I'm really ready to make my game.
