Just got hold of Myracer MF-101 that is a portable game device from South Korea (made in china) and somewhere play4u is a part of the action as well, looks like you can get a lot of new games from there (I don’t understand Korea).

The MF-101 comes with some built in applications as, Game, Movie, Music, E-book, Image Viewer and of course has some custom settings. At a first glance the device it seems very inspired from the PSP but it’s much smaller in all the ways and very light. It has 1gb inbuilt memory but has a SD-Card slot if you want to expand, must say that the USB plug is strangely placed. The whole cool thing about this portable game device is that it has a Flash Player.

Comparing some of the values it doesn’t match, take the screen resolution for e.g. The SLF engine automatically resize the SWF file so run 320×240 else it will be scaled. Another value that doesn’t match is the Player version, I’ve tried a couple of Flash 8 features and it crashes so go for Flash Player 7. In the documentation MyRacer speaks of their own Flash engine SLF (SCD Light Flash Engine).

I starting of by running a Flash Lite 2.0 320×240 swf to find out the controls.

The SLF Engine has a couple of features built-in, instead of the Flash Lite fscommand2() I found the functions in _global.WRTAmuse, so for example checking the battery level is done like this. It gives me 0-4 of the power strength and 5 if it’s recharging.

var battery: Number = _global.WRTAmuse.Common.getBatteryLevel(4);

There are as well a way to get hold of files in the system but I haven’t been able to get hold of all the methods due WRTAmuse doesn’t give any data back.

var fcount:Number;
fcount = _global.WRTAmuse.Common.GetFList("flashplayer");
if (fcount < 0)
{
	for (var i = 0; i < fcount; i++)
	{
		trace(_global.WRTAmuse.Common.GetFile(i));
	}
}

After created a couple of games I noticed that I got problems with the key controllers. Noticed that only two keys are registered and when using a third key will lock one of the first keys and not register the release. The key dispatcher doesn’t quite work as a ordinary desktop player. The desktop player sends the latest key pressed/released but the SLF engine sends all keys pressed but it can still miss the “lock” release.
