I've had these questions regarding modding this game lingering around me for a while, since AT7View was out and the Rumble Weekend mod:
1. Will there be a model importer and/or a proper recompressor for the arc.cx files? (I don't know which one is causing me to have the most issues, but either one is not letting me do the model importing)
2. Is it possible to add Pokémon data entries to the game?
3. Is it a possibility to add new moves in the game?
These might be really hard to do, but its something I really want to see happen in the future, and I'd love to see progress of it as well if I'm allowed to. I'd already be happy enough with the first two questions, but the third would make it better.
