I can copy and paste too hurr.... 

You are a complete fool. The rpg_rt I included is the ENGINE FILE for the maker, and its been hacked to show 120 pictures. You are supposed to take that engine file, and put it in to your games folder and obviously, overwrite the one that already exists. There is no simpler explanation. There is no need to overwrite any .dat files and absolutely no need to rename my engine file to .dat
The last thing I want to do is insult someone in my own thread which is meant to help people, but moronic statements like yours bandito just tip the scales of patience I have.
1) copy rpg_rt from my zipfile
2) paste into your games folder. (you DO have a game made already right?)
Just 2 simple steps bandito.
EDIT:
looking back, look at yourself bandito, you are proving
yourself wrong. In my picture, I'm clearly showing you to replace the rpg_rt.exe in the PROJECT FOLDER, and yet in your picture, you are trying to replace the one in the RM2K3 folder.
