It seams, that I have tracked down the problem with v1.1.3 to the handover via kbook.autoRunRoot.xyz in the starter script.

By avoiding any references to Core I am able to have Fiverow on my PRS-505

Spoiler:

var getSoValue, newEvent, hasNumericButtons;
..
..
target.init = function () {
/* Core workaround  */

      	if(!kbook || !kbook.autoRunRoot || !kbook.autoRunRoot.getSoValue){ 
      	  		if (kbook.simEnviro) {
      	  			//	this.bubble("tracelog","505 branch - SimEnviro");
	      	  		getSoValue = _Core.system.getSoValue;
				hasNumericButtons = _Core.config.compat.hasNumericButtons;
      	  		} else {/* PRS-505 */
      	  			//	this.bubble("tracelog","505 branch - Device");
        	  		getSoValue = function (obj, propName) {
        			return FskCache.mediaMaster.getInstance.call(obj, propName);};
 				hasNumericButtons = true;
      			}
			var compile = getSoValue(prsp,"compile");
			newEvent = compile("param", "return new Event(param)");
	 }else { /* code is ok with PRS-600 */
		//	this.bubble("tracelog","600 branch");
		getSoValue = kbook.autoRunRoot.getSoValue;
		//	this.bubble("tracelog","getSoValue "+getSoValue);
		newEvent = prsp.compile("param", "return new Event(param)");
		hasNumericButtons = kbook.autoRunRoot.hasNumericButtons;
		//	this.bubble("tracelog","hasNumericButtons "+hasNumericButtons);
	}

There are still problems:

1. "MENU to quit" is overlayed by the (blank) Volumebar (see screenshot)
2. buttons 1+2: there is no action at the moment !?
3. I tried the same workaround in my latest sudoku-code but the game refuses to accept button-input

After sorting out the Num-button problem, I will post a complete package.

Furthermore, I just converted FiveBalls to Touch using the Test Environment, and then incorporated it into my custom-build of PRS+ and loaded it onto my PRS-600. Everything works fine

If you will try Mahjong too, there is a non obfuscated version in clemenseken's thread here.
