Left/Right Arrows for next/back. I apologize for leaving everyone in the dark about this project for the last few years. If you haven't guessed yet, Pokemon Fusion is not going to release. I tried making it on Scratch, but I kept hitting roadblocks with both Scratch and my programming abilities. Later on, I restarted development and began making the game as a ROM Hack of Pokemon Emerald. I was just going to insert my Pokemon Fusions into the game over the old Pokemon and change the movesets and such. Pokemon Emerald hs over 200 Pokemon though, which meant I had to make over 600 sprites. Eventually I just lost motivation for the project. Additionally, I was experience a lot of technical difficulties with conflicting file formats and color palettes. The sprites in this project are the results of development as a hack of Emerald. Some do not have back sprites and some are unfinished.
