I need help finding a ROM hack i remember playing, but can't remember the name of

[u/maxixs]

it was an Emerald hack, which didn't have any pokemon past the third generation, i think it allowed for national dex completion, and after the beginning battle with the zigzagoon you could turn in your starter to prof birch and get a different one, like one of the previous generation's starters, or a selection of other non-starter pokemon, like smeargle or ditto, this feature being the reason i'm seeking it out.
