Requisites:
All files needed (can't put it here anymore): Mod files on github.
Here's how to make ir work:
You need Amy unlocked:
-You just need a full save file. Take care to not replace your previous one. I attached it on that github repo.
-You can the normal way too: "Collect 5 Emblems, to unlock Frozen Hillside (if you haven't already), go to Extras, go to Frozen Hillside, and complete the Zone."
-Ami texture: Ami texture.
-Go to models/PLAY and backup AMY.png and then replace it with this one I linked
-Custom Color addon, you need to activate that every time you boot the game: L_CustomColor-v1.pk3.
-Put that on addons folder and enable that in the addons menu in the game eveytime you open it.
Sumary: after those stepes were done, open the game, addons open L_CustomColor-v1 then new game and select Amy. It should be all fine from there.
