Replace most name with index.
So model_cache will not be freed unless the forced memory clean up is called or the game shuts down.

Ooops... missed ramblock

gp2x fix for memoryAvailable()

Sprite rotate works now, might be slow but it works with scaling.

Not good with alpha blending because some pixels are drawn in the same positions.

Don't try knife again if stars are spawned.

Check custpshotno Or custknife instead of And in throwframe check section.

Scriptengine: bgspeed, bgdir can be accessed by changelevelproperty.

spritef.c: add a rotate method, not completed.

Change in sprite scaling code, now the y offset seems OK, it used to shift up or down by 1 pixel if the scale-y value is not divided by 256.

Hard coded star and knife section, it should not crash now instead it will check between the 2 and find the valid one.

Landframe and dropframe should be applied only once or frames behind them will be ignored.
