There only semblance of the story is the very beginning of the game where you and your rival go to the lab and get your Pokémon from the Gen I rival and then battle each other. But there are no teams set up in the game other than the Trainers made specifically for the demo, so your rival's team will be some selection of bytes from somewhere in the ROM. On one hand, there are 251 Pokémon and 256 bytes, so your chance of encountering a glitch Pokémon is like 5/256. On the other, your chance of encountering a Pokémon above level 5, the same as your starter, is 250/256, and encountering a level 1 or 0 will crash the game. The game will typically crash around this point, and even if you get past it, there's nothing really to do. You can't talk to anyone past the tutorial area Shizuka Oka (Silent Hill, but not the starting town which is Silent Hill in English).
The ROM is a novelty, and you can learn more about production from interviews, being familiar with Japan, and just piecing together what you can of the overworld. The map is clearly meant to represent Japan in its entirety. Most GYM buildings say LEAGUE and start off with a classroom followed by a room with four Trainers and the leader, making it apparent that you're challenging each region's League Champion, hence why Red (or Satoshi as he would have likely been known) is present in the Kanto one. Every locale name is wordplay on a real life Japanese locale
Silent Hill = Shizuoka
Old = Nagoya
Blue Forest = Aomori
Prince = Fuji
Stand = Sendai
Niigata = Newtype
North = Hokkaido
South = Kyushu
West = Kinki/Kansai
Kanto would have been East if it didn't have a name already
etc.
But "completing the ROM" is like that whole Red and Green prototype fiasco where they added fanmade sprites. Anything they do is speculation.
