All credit goes to 'elimanene' on youtube for this creation.
Elimanene has created a pokemon game that doesn't run on an emulator, it's a whole program by itself. It's got Black&White graphics, but plays like HeartGold&SoulSilver in a way. The bottom screen looks similar to the one in HG&SS, from what I've seen. I've never played them, so I don't know if it's actually like identical. The program is Gen 5 Red&Blue (or Green in Japan), except it has a lot more added to it. It uses a lot of camera angels, as you can see as you watch the demo video. The only reason the demo video is really laggy is because the person who made it, his computer isn't the best. below it, I'll post a playthrough of it from someone else I found on youtube, but can't remember his name. Also, the demo only goes up to Mt. Moon, but it's a really cool thing to play, and I recommend it to anyone looking to play a new game.
