I'm compiling this now, maybe I can find the problem. So far, I noticed this in H2.c:
parts[i].temp = 999999999999999999999999999999;
pv[y/CELL][x/CELL] = 9999999999999999999999999999;
These are way too big, make them smaller. I can't compile a number that large. I'm going to change it to 99999

Edit: same in hlum.c
Also, I had to fix visual studio problems caused by an old source, not your fault though. If all you added was elements, maybe I can try porting it to a new version later. What did you change besides element files? I see the name on top and in the hud is different too.
Edit2: I'm trying to figure out how to compile TROL.c, maybe i'll remove the SING update function randomly pasted there, in the middle of something else

Edit3: get it here. I made the changes listed above, and I also made it able to load newer saves, but it doesn't work on saves that have tmp[3+4], because that's something added in a newer version. Also, I changed something minor to make the thumbnails from tpt++ look better. I never found why it didn't work, the source was fine.
