I've got your support bro! I tried making a Blue remake years ago. Some ideas - try to add some story elements from the manga to make it more interesting and some things from the anime too. I wanted to add the Battle Pyramid in the route right before Pewter City in my remake, as it appearing in the anime. Of course, it wouldn't be available until the player beat the Elite Four and such. Ideas like these would make your game more unique. Ask yourself, why would I play this if I could just play HeartGold or even FireRed on an emulator?
