I am pretty sure this system is alright but just to be sure is it okay my team base our game on the Nintendo entertainment system. it was released in japan in July 15, 1983 as the famicon then released as the NES in the UK and US in 1986 if the is an issue with us saying we are doing the NES we can just base it on Famicon even tho it won't make any difference gameplay or graphically or audio
