I upload here a script to start sketch from KSM.
- extract the folder sketch from the archive you can find here into .adds of your device
- extract the script start_sketch.sh from the archive uploaded to this post into .adds/kbmenu_user/scripts
- start sketch by selecting (ksm home) "user scripts" > "start sketch.sh"
On some Touch devices you will have to set the variables SKETCH_UNSWAP_XY and SKETCH_UNMIRROR_X in start_sketch.sh to the value 1.
