Title: GBC Mobile trainer unused graphics
Post by: Lain_Iwakura on May 29, 2018, 09:54:08 pm
Hi first time here. In amidst all the hype surround the multitude of unused Pokemon materials I decide to look for the unused sprites of Pokemon referenced by this passage "In the internal data of the Mobile Trainer ROM, graphics for Pokémon such as Pikachu, Porygon2 and Tyranitar have been found." of this article https://bulbapedia.bulbagarden.net/wiki/Mobile_Game_Boy_Adapter (https://bulbapedia.bulbagarden.net/wiki/Mobile_Game_Boy_Adapter).

I didn't see any documentation online so I took into my own hands and found them in the rom starting around offset 00101A00 and scattered througth the ROM from that point on.

Here are some samples, although in the wrong palette

As i'm new to this could I please get some help with properly arranging coloring and documenting these sprites? Thanks :D

Interesting good job that's a nice find! How did you go about locating these?

IIRC graphics are stored uncompressed, and there are programs that allow viewing the ROM as images. You then have to splice the tiles together.
But maybe you did differently?

Yeah, I found them by looking at the ROM in tile layer pro starting at 00101A00 about 50% through the ROM.
