if you run tmodloader on an _old_ computer with an equally old video card, and try to run Elemental Unleash, then you recognize the follow;
Microsoft.Xna.Framework.Content.ContentLoadException: Error loading "tmod:Bluemagic\Effects\WorldReaver". This file was compiled for the HiDef profile, and cannot be loaded into a Reach GraphicsDevice.
i figured out a "kludge", and will try to explain how i got it to mostly work.
this guide assumes some things, notably that you are on a windows 7 computer. if you are not on windows, you can adjust as needed. if on windows, but not 7, i cannot guarantee anything. unfortunately, access to installed terraria 1.3.5.3 is required, but steam or gog should both work.
edit; if Blushie tells me to remove this, i will do so asap. all original code, etc, is not mine.
reedit, file has errors, will try again in a moment
rereedit one more try! i assume its the right revision this time lol
rerereedit nope, wrong another revision, sorry to the one person who downloaded it, and now cant get it to work
