Terraria 1 3 5
Well, theres no longer going to be a need for RomTerraria in its current form.
The core piece of RomTerraria (resolution unlocking) is now fully integrated into Terraria proper. Specifically, the code I wrote to unlock higher resolutions is literally inside Terraria 1.3.5s Terraria.Main.TrySupporting8K() method.
With that, my job is done and RomTerraria is going to be going on hiatus while I figure out what, if anything, I can do with the game.
