Re-Logic released Terraria 1.3.3 about an hour ago, after I had already left for work.
I do not know if 1.3.3 breaks RomTerraria or not. Ideally, it shouldn't.
If you patch 1.3.3 with RomTerraria and it crashes once, please try running it one more time. There appears to be a race condition on first launch with larger display sizes.
I'll check 1.3.3 out when I get home from work tonight. I'd love to do it sooner, but working on free mods doesn't pay the bills.
[Update 9/10/2016 10:46am: Working on a fix now.]
[Update 9/10/2016 11:02am: The main render target changed visibility, and a new render target was added. However, other variables changed. Still working on it.]
[Update 9/10/2016 11:26am: All variables updated. Working on updating a couple of method calls.]
[Update 9/10/2016 11:40am: New version uploaded. Read the instructions, as they have changed.]
