> Make a randomizer using RAM values
nah that ain't it. that's insane overengineering. RAM is already a super stretched resource in most games on classic consoles, so it may not even be possible depending on how much the original game uses (forget the NES). just find the values you want to randomize and edit / rebuild the ROM. it's how most randomizers work anyway.
not to mention that every combination of everything you'd want to change probably wouldn't work (item order in Metroid for example), so, you'd want a higher level modern language to write rules to have actually playable / beatable seeds. fuck doing that in classic console ASM.
