The biggest pain in the bum with early consoles like the NES is all the cartridge hardware you have to muck about with. I'm sure most of you reading this already know but the gist of it is that NES cartridges had their own special chips inside them that were there to improve the abilities of the NES over time. Stuff like better scanline interrupts and Japan only sound chips (Due to changes to the cartridge port in the west) which you'll probably know about if you decided to listen to Castlevania 2/3's soundtrack on Youtube and found it different to what you remembered. The most common feature was to turn the character rom into a pseudo or even proper RAM so you could use way more graphics and tons of nifty techniques that made stuff better. Anyway, from a quick sift through this looks like a good site and far nicer than a lot of console development sites. (Sorry coranac, your site is a goldmine but the tiny font against that background gives me a headache)
