Make Register Access Consistent about cosmic

[clbx]

The given example is wrong. The issue is actually between two MOV functions.

[clbx]

0x39 and 0x33 use registers differently

[clbx]

Should check the following

Cosmic/src/cosproc.cpp

Lines 353 to 362 in 4c5f7c7

	/* 0x17 ADDXR */
	void cosproc::ADDXR(uint16_t src){
	uint16_t data;
	if(src % 2 == 0){
	data = ((r[src] << 8) | r[src+1]);
	}else{
	data = ((r[src-1] << 8) | r[src]);
	}

And all similar uses

Cosmic/src/cosproc.cpp

Lines 728 to 732 in 4c5f7c7

	void cosproc::MOVXAR(uint16_t src){
	uint16_t dst = ((Read(pc+2) << 8 | Read(pc+3))); //Get the 16bit destination
	Write(dst, r[src]);
	Write(dst+1, r[src+1]);
	}

and all similar uses
