heres how sprites are set up:
Byte 1 xxxxxxxx x: X coordinate
Byte 2 yyyyyyyy y: Y coordinate
Byte 3 cccccccc c: starting character (tile) number p: palette number
Byte 4 vhoopppc v: vertical flip h: horizontal flip o: priority bits
Note: the 'c' in byte 4 is the MOST significant bit in the 9-bit char #.
the 4 writes into the $0200 area represent these 4 sprite config bytes.
everytime the above routine is executed, one sprite is drawn.
that means this one here controls the y position of all sprites in the logo:
$00/93A4 A9 70 LDA #$70
and that one controls the palette:
$00/93AF A9 30 LDA #$30

thanks. 
however, i think that this is only a minor thing.
when i was done with the new intro for icemans hack, i just wanted to remove the original nintendo logo and the bling-sound asap.
a quick search for accesses to the apu ports and for writes to the oam data buffer in wram and i was done with it.
so this logo thingy was actually just a small side-effect of another hack.
btw, i dont like sprites pretending to be background layers that much. :>
unless i have no choice (mode7), i avoid it at all costs.

WTF? I see the code, it's right before my eyes, but I can't see what bytes to edit in the hex editor to change the palettes! And if I were to edit them in a hex editor, how would I go about doing that? Is it 3 bytes, for Red, Blue, and Green? BTW... If you open level C7, would you Enable Custom Palette? I'm guessing yes, but that does not do it for me... |

Hey, neat. I believe that's the same code I hooked to add sprites to my intro way back when. I couldn't remember where it was located, and I wanted to change a few things...

It's as simple as that. You can't use anymore than the first 8 colors, which sucks, but until some smart guy comes along and fixes that we're stuck.
the sprites and palette number selection occurs here:
$00:939A
$00/939A A0 0C LDY #$0C A:0000 X:00FF Y:00FF P:eNvMXdizc
$00/939C A2 03 LDX #$03 A:0000 X:00FF Y:000C P:envMXdizc
$00/939E BD 89 93 LDA $9389,x[$00:938C] A:0000 X:0003 Y:000C P:envMXdizc
$00/93A1 99 00 02 STA $0200,y[$00:020C] A:0090 X:0003 Y:000C P:eNvMXdizc
$00/93A4 A9 70 LDA #$70 A:0090 X:0003 Y:000C P:eNvMXdizc
$00/93A6 99 01 02 STA $0201,y[$00:020D] A:0070 X:0003 Y:000C P:envMXdizc
$00/93A9 BD 8D 93 LDA $938D,x[$00:9390] A:0070 X:0003 Y:000C P:envMXdizc
$00/93AC 99 02 02 STA $0202,y[$00:020E] A:0008 X:0003 Y:000C P:envMXdizc
$00/93AF A9 30 LDA #$30 A:0008 X:0003 Y:000C P:envMXdizc
$00/93B1 99 03 02 STA $0203,y[$00:020F] A:0030 X:0003 Y:000C P:envMXdizc
$00/93B4 88 DEY A:0030 X:0003 Y:000C P:envMXdizc
$00/93B5 88 DEY A:0030 X:0003 Y:000B P:envMXdizc
$00/93B6 88 DEY A:0030 X:0003 Y:000A P:envMXdizc
$00/93B7 88 DEY A:0030 X:0003 Y:0009 P:envMXdizc
$00/93B8 CA DEX A:0030 X:0003 Y:0008 P:envMXdizc
$00/93B9 10 E3 BPL $E3 [$939E] A:0030 X:0002 Y:0008 P:envMXdizc
see where it fetches the sprite config data from?
now you can edit the palette number and tile numbers of the nintendo logo right away with a hexeditor.
have fun! |

For the record, don't try to fix the tags in your own posts, that only super complicates matters when we're trying to clean up the mess. If you need a mod right away, just PM me or another SMW mod (or if a Full Mod or Admin is the only one on, PM them). I'll probably get to it fairly soon after you send it. I've got no life, you see. |
