Lack of time, motivation, and having a lot of different ideas and projects in mind (not related to Pokémon). Also one of the biggest factors is that I started my Emerald rom hack in spring of 2018. Since then, a whole new pillar of 3rd gen rom-hacking had emerged - dissasembly. Though I completely understand it's importance and convenience, I have nor time nor desire for learning how to use it. In turn, my rom-hack becomes outdated. Still, I'm planning on finishing that thing in some form or another sometime in early 2020s and move on to something else. Don't wanna leave my little hack in the dust on my hard drive.
