1. When you need to put schematic of a board, put actual schematic of the board (as an image), instead of terrible ascii art as it is case with e.g. UNROM-512 schematic on the wiki.
2. When putting code samples, translate it to most used assemblers (in this moment AFAIK that would be ca65, NESASM and ASM6) as to not confuse new developers with assembler differences so they wouldn't have to translate it themselves and instead they could easily see it in a syntax they're most comfortable with (unless it's some exotic assembler in which case the dev probably knows what he's doing anyways).
I feel like if these two suggestions would be followed up on and put into practice across the wiki, it'd be much better source of information for developers new to NES.
