This is some data I identified today while messing with Batman 1 (NES). Format is simple:

[hexadecimal] (Address) - [hexadecimal] length of data - Description

Updated 8/17/03.
Updated 8/25/03.

Batman.nes : 262,160 bytes : CRC32 / $395569EC or $CECEAA31*

*description of the difference between the two CRC32's:

One byte in the iNES header is changed (the seventh byte) from $40 to $41. All this does is change the PPU's default mirroring scheme (between horizontal and vertical). This has no effect on the actual game performance or output because it uses the mapper (MMC3) to set the mode it wants to use before doing the PPU work.

$00000 - #$10 - iNES header
$00010 - #$03 - ASM
$00016 - #$3F6B - Music
$04110 - #$06 - ASM
$04591 - #$31 - ASM
$045DA - #$29 - ASM
$04722 - #$13 - ASM
$047B8 - #$18 - ASM
$0483E - #$14 - ASM
$048B1 - #$41 - ASM
$048F9 - #$0C - ASM
$04915 - #$0A - ASM
$049A0 - #$19 - ASM
$04C62 - #$1E - ASM
$06B40 - #$17 - ASM
$06B63 - #$0A - ASM
$15D38 - #$2B - ASM
$1C450 - #$20 - ASM
$1C487 - #$05 - ASM
$1C492 - #$0B - ASM
$1C4C3 - #$07 - ASM
$1C4F5 - #$0E - ASM
$1C5FD - #$35 - ASM
$1C632 - #$0F - ASM
$1C7B2 - #$07 - ASM
$1C87E - #$2D - ASM
$1C8AE - #$22 - ASM
$1DD38 - #$2B - ASM
$1ED3A - #$8C - ASM
$1EE05 - #$57 - ASM
$1EE73 - #$06 - ASM
$1EE93 - #$17 - ASM
$1EF11 - #$11 - ASM
$20010 - #$20000 - Graphics

Nearly all of those marked ASM are really part of a much larger section of 6502 code.

Credits to the NSF ripper for making finding the Music data far easier. Credits to SnowBro for making Tile Layer Pro. But most of all, credits to Sunsoft for making the Music and Graphics so easy to find (at the beginning and end of the rom, respectively).
