A month ago I made a simple Red/Blue hack that just replaced the Pokémon sprites with the Spaceworld ones. Now it's been renamed and has a lot more content.

- Lots of Spaceworld graphics: Pokémon, trainers, tilesets, NPCs, SGB borders, trainer card, Pokédex, etc
- Shiny Pokémon, with the 1/8192 rarity from G/S
- Catch all 151 in one game
- Hold B for 2x Running Shoes (or 4x Mach Bike)
- Talk to use Cut, Surf, and Strength
- Gym Leaders and Elites have better moves
- MissingNo still exists and still clones your items

Patch downloads, screenshots, complete features, and source code are available on GitHub:
