Tileset Differences

Hex	Proto	Final	Status
0x04			The small flowerpot and lower-left side of the tombstone have their assigned palette swapped around, which can be seen in the Soul House in the prototype.
0x06			The sprite for the PC doesn’t have its unique design yet, instead reusing the one used in tilesets 0x04 and 0x07. The 16×8 tile below it was also redrawn.
0x07			The shading on the green corner tiles is darker than in the final game.
0x08			The tileset for the ports showcases quite a few differences. Indeed, the shading on the stairs and tiled floor is different, and parts of the S.S. Anne (as well as the walkway leading to it) were also touched up. The water tile and "pillars" are more akin to the ones used in Generation I. Moreover, some of the placeholder tiles were also replaced in the final version.
0x0A			The horizontal cables are brown in the prototype, but pink in the final game.
0x0B			The tileset for the Poké Marts also features some interesting differences, with cash registers facing the opposite way and the tiles for the shelves having either different shading or a slightly different design.
0x0C			The tileset for the Celadon Condominiums shows a few differences here and there, namely with the shading being different in a few spots and the door tiles being more akin to the ones used on the S.S. Anne. Worth noting is that the early tileset lacks the tile used for the floor pattern, instead using one resembling the tile used to denote sand/beaten paths in the overworld. Interestingly, both Generation I and the Spaceworld '97 demo used a similar floor tile, suggesting that this change happened rather late in development.
0x0D			The tileset for the Game Corners and the Olivine Café/Celadon Restaurant features a different design for the floor pattern, slot machines, tables, and plates. Interestingly, the early tileset also features tiles for descending stairs, which may imply that the Team Rocket Hideout could have been planned to make a return, as in Generation I a set of descending stairs leading to the Hideout spawns after defeating the Rocket Grunt defending the poster. In the final game, Celadon City's Team Rocket Hideout doesn't exist, and the descending stairs tiles were overwritten with extra object graphics. Strangely enough, some tiles for the ascending stairs can also be found in the early tileset despite there being no reason for them to be here, and regardless of the reason they were also overwritten in the final game.
0x0E			The tileset for the Gyms and Elite Four rooms features quite a few missing tiles, while a few others, such as the one used used for the back wall in Goldenrod's Gym, were overwritten with different ones in the final game.
0x0F			The two halves of the fence sprite are assigned a grey palette in the prototype, while in the final game they are assigned a brown one.
0x10			The tile for the train's lit up window is missing in the prototype. Meanwhile, a lot of other tiles (seats, flowerpots, machine parts, floor, etc.) have a different design or were replaced with totally different ones in the final game (the pillars with the green "N&B Blocks", for example).
0x11			The tileset for the Goldenrod Bike Shop shows some very minor shading differences on the bikes, as well as the back wall being green instead of grey.
0x12			The tileset mainly used for the S.S. Aqua features a few tiles with missing shading (shelves) or a different palette (PC and stone walls). Some of the placeholder tiles were also replaced in the final game, while the bed tiles were redrawn.
0x14			The tiles for the floor and Bellsprout statues were improved in the final version, and so did the ascending stairs as well as how the fence sprites are handled. Moreover, an error on the left side of the rug sprite was fixed in the final game.
0x19			The Persian statues are brown in the prototype, but yellow in the final game.
0x1A			The TV screen of the Hall of Fame machine is brown in the prototype, but blue like the rest of the machine in the final game. The corner sides of the machine were also touched up slightly, and so did the back wall, which uses a rather odd-looking green tile. In the final game, two of the placeholder tiles were replaced by the tiles used for the final wall design, and while the green wall tile one was removed the placeholder tile in its spot still uses its green palette.
0x1C	N/A		This tileset, which is used for Ilex Forest in the final game, is missing entirely in the prototype. As such, Ilex Forest instead uses the standard tileset 0x00, which in turn causes the map to look much more bland (due to it lacking the special large tree). Interestingly, the sign tiles used in the 0x00 tileset are also present in the 0x1C one, albeit unused.
