I have downloaded the Mars MIPS Simulator .jar file, and I have downloaded the java jdk file from oracle. Whenever I open the jar file, the IDE is there, but everything is greyed-out. I can't even edit the text in the window. When you select "Execute", three cut off windows appear in the box below, one titled "Text Segment", one "Data Segment", and one "Labels". I am thinking it is a failed installation, but I have no idea what else to do. Thank you for any help!
Here is a screenshot:
Hey I had the same problem! Just use the toolbar on the top and click paste and the edit window should work. And after you hit assemble, go to settings->Show labels window. Hope it helps!
