To overcome the emulator enhancer's message box, a simple applescript can be run:
delay 5 activate application "KiGB" tell application "System Events" tell process "KiGB" click button "Maybe Later" of window 1 end tell end tell
This script must be saved as an application bundle, and without a start dialog. Otherwise it won't run on the AppleTV - at least on (my) ATV 2.3.
Obviously the name of the application and the process has to be adapted to the desired emu.
My hope is, that this script can be run automatically by the plugin. First the plugin should load the emu, then launch the script. To make applescripts run on ATV, you just have to use the nitoTV smart installer.
Today I downgraded from 2.3 to 2.1 and I found out that AppleScript doesnot work after NitoTV's smart intaller. As I have a 1.0 recovery partition i simply copied all missing files from that volume to my OSBoot. After that AppleScript works fine. But be carefully. After that "update" the latest softwaremenu doesn't work anymore.
