It's unlikely. First of all, Gen 1 combined Pokémon and trainer IDs, so splitting those up to make room for 251 Pokémon would be complicated (especially since I'm less experienced with pokered than pokecrystal, and its code is messier). Second, some of the Spaceworld Pokémon would be pretty disappointing without their new moves, held items, or sensible locations.



What I can imagine is, instead of porting Spaceworld content to pokered, port Gen 1 content to pokegold-spaceworld when it's more completely disassembled. Then, backport the Sevii Islands from Gen 3: they're perfect for showcasing new Pokémon and tiles, and I can tweak the layouts to resemble the Spaceworld maps (e.g. those pyramids for the Tanoby Ruins). That would even benefit from the minigames, like Picross and the 15 puzzle, which can go in the Game Corner on Three Island.

That makes sense. I hadn't realized there were that many demo mons, it's not something I've looked at too closely yet.
