Pokemon Emerald Imperium is a QoL / difficulty emerald hack with a slightly altered story that is fully beatable through the Champion battle (and has a little post-game). I’ve also added some characters from Gen 4, namely Dawn as an additional rival throughout the game, all the Gym Leaders as optional trainers to fight (except Roark, he’s mandatory), and more!
Other notable features and additions include a built-in randomizer, a couple of difficulty options (just Easy and Normal for now, maybe I’ll add a Hard mode in the future or something), several new Mega evolutions, including all the Sinnoh starters, and a whole lot of balance changes to various mons. It’s also got every QoL / feature branch under the sun in there somewhere, so I won’t list them all here.
I’ll probably come back and edit this message at some point to include links to the docs and other things that I’m still polishing up, which will list everything in excruciating detail. I’m sure this game won’t be many folks’ cup of tea around these parts, but I still wanted to post it because I am happy with myself for sticking with this for so long, making the game that I wanted to make, and getting it to a place where I am comfortable sharing it with others.
Also as you will see in the credits, many of your guys’ assets, features, and ideas are in the game somewhere, and I definitely would not have stuck with this project for so long if it weren’t for the homies here, so it is definitely a community hack in that sense.
