Hi hi, this is I again ( the person that posted the last 3 posts, lol ).

I have a wierd problem... I have set no background pattern or anything, but it displays "A0BA" repeatedly over my background in my ROM...
The A0BA are just tiles from my first half of my CHROM... They aren't lined up in any logical way, so, I am guessing that the NES is picking four random tiles from my CHROM and repeating them... Its wierd!
Also, how do I specify the color palette I have defined in the palette ROM area for the background and the sprites and everything...
In the sprites, there is a lil thing you can set ( the color bits ) but, that doens't really tell me which palette I'm using or anything...

I made a simple algorithm for "clearing" the screen ( really, its just the background ) and it goes something like the following:

	;clear screen/background
	ldx #$00
	ldy #$00
ClearScreen:
	lda #$3F ;blank tile...
	sta $2007
	inx
	cpx #$3C
	bne ClearScreen

	ldx #$00
	iny
	cpy #$1F
	bne ClearScreen
