	You just cannot simply reset randSeed in C by :

		randSeed = TickCount();

	because LSC thinks that randSeed is a DA global offset by A4 and
	not A5 (which is what u want).

	What you need to do is use some assembly to access randSeed. Sorry
	but i dont have my notes and docs here so i cant show it to you
	from memory.

	Why dont you use your own random number generator ?
