I ran the app on my patched KRP. I did not use the Change button since I already have ISF enabled. The software works very well. However, I did find a few bugs:
1. The Gamma selection (for non-ISF modes) has Off, Low, Mid, High. "Off" returns an error, and low, mid, high are Gamma 1,2, and 3 respectively. Gamma 4 and 5 are not selectable. Also, the control is not updated correctly when Refreshed - note that the returned gamma value has 2 additional digits appended to it, which is probably the problem.
2. The Film Mode (Pure Cinema) is missing the Smooth mode selection.
3. The Intelligent Mode setting is not available.
The good news is all of these can be entered manually as a workaround in the Command box. For example, sending GMMS04 or S05 for gamma 4 and 5, PUCS03 for Smooth Pure Cinema, and ITMS00, S01, S02 for Intel mode Off, 1, and 2 respectively.
