Hey fellow #Pokemon trainer! I would like to point you to one of my favourite mods:
Pokémon Red++ (v3)
It's an open source project aiming to improve on the base version of Red. Bugs have been fixed and a lot of features like color, updated graphics, more Pokémon/attack moves, player gender selection and additional story have been added.
Best of all, you can compile it yourself without downloading a ROM from edgy sites.
If you are feeling retro, you should give it a go!
