Firstly I don't know if it is illegal (if so then just discard this):

but someone has the http://www.freepatentsonline.com/4824106.html pdf or link to patent file nº 4824106 of ppu nes... ? (I mean with pics and everything..)

thanks in advance

I thought patents were supposed to be viewable to everyone, otherwise nobody would be able to know if they were infringing on them.

Anyway, the NES patents expired a while ago.
