IR-GTS-BW Release in RAM - NDS Research & Development Posted March 23, 2011 Try opening a Terminal, then entering 'chmod +x ' then dragging ir-gts-bw.py into the window. That should allow you to execute the file by double-clicking on it. Otherwise, you can run it straight from the command prompt, if you cd into the IR-GTS directory first. Now I'm getting the same syntax error as hockeyfan607's describing. At any rate, thank you for your help.
