My fake pokemon crystal for GBC is like this, if you start at night , it will be day one time and then night forever xD
the same goes if you start at day etc
the real "updated version" is Blue for Japan (Update from red and green), from this blue come the western Red and Blue ... they don't even make a remake for the "update" so even for an special .... maybe they come with another "anime special" , who knows? it's most probable XD
People seem to get this wrong too often. What I mean is a red "v2" was released with blue. It has corrections of glitches from gree/red"v1" just like blue and a very few but subtle graphic updates. The reason green v2 was released as blue instead as green v2 is because green had far worse glitches and ugly graphics compared to red v1. Thus they wanted some distance from the mess up of green. The problem was red v2 wasn't really advertised and unless you were actively reading Nintendo articles, it was easy to miss red v2. As even the boxes for it were not labeled in any meaningful way.
