Hi. I would love a more advanced overview of NESMaker for someone who is a little bit more experienced with Assembly. Maybe showing how NESMaker sets up the system and cartridge, the cartridge mapper, etc.
I highly doubt that Joe will ever make a tutorial regarding that sort of thing. Your best bet it to dig around the forums for folk messing with more advanced aspects of the program or even just straight up writing their own code.
If you more experienced with Assembly, watch all the tutorial videos, including the ADVANCED ones... and I think you will know everything you need to start digging' in the engine
