Pokémon Blue - 151 had a few simple goals:

1) To make it so that all 151 Pokémon could be obtained in a single-player playthrough, without the need for a guide, or any new special new items or evolution methods. All updates were seriously considered to make the most sense without affecting lore, story, or mechanics.

2) To replace any direct, real-world, location references with updated and relevant Pokémon-world references (Example: Lt.Surge the Lightning American is now The Lightning Unovan, as newer games reveal that he is a native born Unovan.)

3) To NOT go overboard with edits! The project does not add new sprites, new music, new regions, new characters, new moves, higher difficulties, etc… It doesn’t even “fix” attacks. It does, however, slightly edit Fuchsia City so movement is easier (does not introduce any game skips, whatsoever - just a Quality of Life change.)

This is supposed to be as vanilla as it gets, but also to feel as official as it can be. All re-introduced Pokémon are not simply dumped into easy locations, but they are also not impossibly rare - NONE are at 1% spawn rate. - Everything was thought-out for balance and to fit into the already established story (in some cases, improving the story). The entire game should be doable without a guide. Newcomers should be able to playthrough and succeed simply by talking to NPCs and doing battles and exploring. Older fans will be able to do most of this game from memory - It is not supposed to feel like a rom hack.

Update 1.2: Changed one trade so that NPC dialogue post trade makes sense.

Update 1.2.1: Added an optional “MissingNo Patch” so players can re-enable MissingNo encounters.
